Ford focus 2 cranks but won't start. Effective troubleshooting methods ford focus starter

IN THE SUMMER (2.0 liter sedan 2006) six months ago a problem arose - on the go the arrows jumped (jumped) to 0 on the dashboard, the display showed errors: CHECK ENGINE, MALFUNCTION OF POWER STEERING, LIMITED SPEED MODE, FAULT OF THE ESP SYSTEM, ENGINE SYSTEM MALFUNCTION.
After reading the forums, I removed the dashboard, soldered it, cleaned all the connectors with a spray, dried it. Collected…
1-2 days everything was fine ... And again ... Pip pip
It all ended up not starting at all. When the ignition was turned on, the immobilizer often blinked and the starter did not respond to turning the key. After 2 minutes without turning off the ignition, the immobilizer counted error 16 (1 long beep and 6 short beeps). If all this happened on the move, after 10 minutes the power steering turned off in the direction of travel. On the go, he turned on the ignition, and started the engine with a gear (without a gur, a foreign car becomes an uncontrollable piece of metal on the road). If the engine did not start in this way, the starter relay was manually closed on the hot engine, and the other person oiled the gas pedal. On a cold engine, by closing the starter relay, it refused to start.
By such methods, I drove to the officials. Showed and told everything. Found a cable break on the CAN BUS (CAN). Restored. The engine started, the errors disappeared. COOKING.
After 3 months, the same again ... The officials said that they pulled the connector out of the ECU and put it back in - this is the whole repair.
I rode for another 3 months until November, and DAMN, as soon as the cold set in at night (-8 and below), I WOULD NOT START AGAIN. I was ready to sell the car. Decided to finish off this cant, because the rest of the car is completely satisfied. He deduced a pattern - at low temperatures, he put a home heater with a fan under the hood and warmed it for 5-10 minutes. And the car started. Then it began to start after warming up and slamming the hood. Through any time and it did not help. It seemed like the end of the world was near...
All these 6 months, if the car started in the morning, then the day rolled back normally (the arrows jump, and figs). Since it is useless to go to the officials with a warm engine, they are also warm in boxing. Floating fault, which is manifested by current from -10 and below. Not every diagnostician will want to do repairs in the cold. I understood it.
Armed with the information obtained by experience, I went to the officers. The errors in the memory were the same as the first time U1900, etc.. Diagnostics showed a malfunction of the dashboard (15 thousand panel and 3 thousand programming).
Picked up a broken car. Get on the Internet. I read everything I can if anyone has had a similar experience. After reading, I disconnected the battery, removed the air filter, cut the corrugation of the bundle of wires leading from the ECU to the GEM (fuse box). I warmed up the wires using the above method, and I start the engine. With the engine running, I start to feel the wires, iiii YAAAAAAAA errors appeared. He repeated with bated breath. YEAH BABY. Problem found. Then it’s a matter of technology, armed with a multimeter, I call the CAN bus. The wires are intact. I pull the GEM connector - I remember the officials and the richness of the Russian language ... It took me half an hour to find the fault. I press the contacts in the connector, I collect everything back, and my swallow is again on a SURE move.

Ford Focus 2 didn't start in the morning? Well, nothing, breakdowns happen to every car. You need to figure out why you got into your car, but it did not start and fix this problem. The most important thing is that if the engine does not start, but the starter turns, then this problem is solvable. To do this, you need to divide the cases into 3 categories:

However, at the very beginning of your attempts to start the second generation Ford Focus, you need to try the following method. You need to squeeze the gas all the way and start the starter. So, gasoline will not flow into the cylinders and the candles must dry out. Feel free to turn the key and try to start the engine.

If the Ford Focus 2 does not start, then the most common problem lies in the starting system. As a rule, the starter does not turn and various clicks are heard.

Starter does not turn

This is due to a violation of the contact of the wires, the loss of contact, the short circuit of the starter, the failure of the traction relay or the burned-out fuse insert F13.

If you hear clicks, then this is a problem with a weak battery, poor contact, or a damaged traction relay winding.

Starter keeps spinning after engine starts

This is already a serious problem and you need to immediately turn off the engine, then look at the contacts of the traction relay and if they do not stick together, then the problem is in the crankcase clutch. This problem is solved by specialists at the service station.

Starter works flywheel does not turn

The starter works, the armature works, but the flywheel does not turn. Such a problem occurs when the flywheel, buffer spring, drive six, or a loose connection between the clutch housing and the starter itself are damaged.

Ignition

Pay special attention to safety) Use rubber gloves and rubber-handled tools. If the Ford Focus 2 does not start and this is due to the ignition system, then you need to check the operation of the ignition coil and the wiring itself. How to check the ignition coil, see the video.

Today we will find out why the starter turns, but the engine does not start and we will find ways to solve this problem. Let's get right down to business!

The engine does not start due to the ignition, power and start system. If in the morning you cannot start the car, then try to squeeze the gas pedal all the way, activate the starter and only then start the engine. If the spark plugs are flooded, then this method will cause fuel to flow out of the combustion chambers, new fuel will not enter the cylinders and the candles can dry out a little.

Engine won't start due to ignition system

Attention! It can be dangerous) The Ford Focus 2 ignition system is made with high-voltage wires and can be damn dangerous. Therefore, when repairing breakdowns, you need to use rubber gloves and a rubberized tool. We put the car on the handbrake, turn on the neutral and check the integrity of the wires on the ignition coil. If everything is in order, then you need to check the spark in the spark plugs.

Engine won't start due to starting system

Starter does not turn

The most common problem when starting an engine is when the starter does not turn. This occurs when the integrity of the wire contacts is violated, the fuse blows, the traction relay breaks and a short circuit occurs.

If the starter turns, but clicks are heard, then this problem may be due to a low battery charge, poor contact, and problems with the traction relay winding.

If the starter relay is stuck / jammed, but you need to start it, then the starter needs to be closed to a straight line!

There is a situation when the starter turns, the armature works, but the flywheel does not respond. In this situation, you need to look at the flywheel. Most likely it is damaged or the breakdown concerns the crankcase clutch.

The starter turns, but there are problems with the anchor. It may work slowly or intermittently. In this case, look at the battery charge, traction relay contacts and all connections.

When the starter turns after starting the engine, then you need to immediately turn off the engine and change the fuse. The problem may not go away and you will have to contact the minders.

The engine will not start due to the power system

If the Ford Focus 2 engine does not start and the problem is pumping the power system, then you need to check the air filter. If everything is fine with him, then we check the contacts of the injection system. Next, you need to inspect the pump and finish with this, because. if the contacts are in order and the pump is working, then a good minder is already needed.

MALFUNCTIONS ON THE WAY

THE ENGINE WILL NOT START

General engine starting techniques

The methods of starting an injection engine are the same at any temperature of the outside air and liquid in the engine cooling system.

To start, just turn on the starter without touching the accelerator pedal. The engine management system will independently set the fuel supply and ignition timing parameters necessary for starting.

1. Open the hood by unlocking it with the key.

2. Measure the oil level with a dipstick. It should be between the top and bottom marks.

3. Check the coolant level.

4. Carefully inspect the engine and engine compartment. Pay attention to drips of gasoline, oil, brake and coolant fluids. Make sure the electrical wiring is intact. Check the fit of the high-voltage wires in the sockets of the ignition coil, on the candles.

5. Without closing the hood (cover it in case of rain or snow), get behind the wheel. Turn on the ignition by turning the key in the ignition switch (lock) to position "II". This will turn on the electric fuel pump. Start the engine by turning the key in the ignition switch to position "III".

_Helpful Hints

It is better to close the hood after the engine starts to work. Before this, it is advisable to once again inspect the engine, make sure that there are no leaks of fuel, oil, coolant, extraneous sounds in its operation. If, for any reason, during an unsuccessful start attempt, the spark plugs are “flooded”, use the cylinder purge mode. To do this, press the accelerator pedal all the way and turn on the starter. There is no fuel supply in this mode. And excess gasoline is removed from the cylinders by a stream of fresh air, while the spark plugs are dried. After purging, try starting again in the normal way.

If the engine does not start, there are three main reasons:

The start system does not work;

The ignition system does not work;

The power system is not working.

_Note

In addition to the main reasons listed, the engine may not start if the canister purge valve malfunctions or if air is sucked through the hose connections of the fuel vapor recovery system.

Faults in the starting system

Malfunctions in the starting system are manifested in the abnormal operation of the starter. The following five main starter malfunctions can be distinguished.

1. The starter does not turn on. The reasons are the burnout of the F13 fusible link in the fuse and relay box installed in the engine compartment, broken contact connections, an open or short circuit in the starter switching circuits, and a malfunction of the traction relay.

2. When the starter is turned on, multiple clicks are heard. The reasons are a malfunction of the holding winding of the traction relay, the battery is very discharged, the contact connections in the starter circuit are loose.

3. The starter turns on, but its armature either does not rotate or rotates slowly. Causes - the battery is discharged, the contact connections are broken, the contacts of the traction relay are burnt, the collector is dirty or the brushes are worn out, the interturn or short circuit in the windings.

4. The starter turns on, its armature rotates, but the flywheel remains stationary. The reasons are loosening of the starter attachment to the clutch housing, damage to the teeth of the flywheel or drive gear, slipping of the drive freewheel, breakage of the lever, drive ring or buffer spring of the starter drive.

The Ford Focus 2 car is very reliable, but breakdowns still happen. For example, in the morning you get into your car and try to start the engine, but it won't start. Repeated attempts do not bring results. However, you should not be upset, because nothing bad has happened yet, and the problem can be easily solved.

An engine that is in good condition should be easy to start in any weather without the help of the gas pedal, and the electronic engine management systems independently set and determine the necessary operating parameters. In our article, we will talk about why the engine does not start, the starter turns, but there is no result, and how to deal with it. In most cases, the problem is:

  1. Launch system.
  2. Ignition system.
  3. Supply system.

Launch system

It should be noted that before climbing under the hood and looking for a malfunction, you need to try to start the engine using the method described below. So, squeeze the gas all the way and activate the starter. In this case, gasoline will not enter the cylinders, excess fuel will pour out of the combustion chambers, and the candles will dry out. After that, we are trying to start the Ford Focus 2 engine in the usual way. The fact is that in case of unsuccessful attempts to start the engine, the candles can be filled with gasoline, and this method can be a way out of the situation. If it doesn't help, we'll look further.

As a rule, the most common cause of starting problems lies precisely in the starting system when the starter does not work properly. The following breakdowns are distinguished:

  1. The starter is not turning. This may be due to the combustion of the F-13 insert in the fuse and relay system, which is located under the hood. Also, the problem may lie in a violation of the contact of the wires, a short circuit in the starter activation circuit or loss of contact, breakdowns of the traction relay.
  2. The starter spins, but is accompanied by strange clicks. Such a malfunction may occur due to problems with the winding of the traction relay, low battery, weak contacts in the wiring.
  3. The starter turns, the armature works, but the flywheel does not function. This can happen due to damage to the flywheel itself, breakage of the drive ring, lever, buffer spring or drive gear, in a weak connection between the clutch housing and the starter.
  4. The starter turns, but the anchor works poorly, that is, slowly. In this case, you should pay attention to the condition of the battery, to the connections, the contacts of the traction relay, the collector, etc.
  5. The starter continues to turn after starting the engine, because the crankcase freewheel is faulty or the traction relay contacts are stuck together. If you encounter such a problem, immediately turn off the Ford Focus 2 engine.

If such problems occur, you can change the insert in the fuse system, check the battery and tighten the contacts in the starter wiring. However, if the problem has not disappeared, then you need to seek help from specialists and understand more deeply.

Ignition system

Before proceeding to check the ignition system on the Ford Focus 2, it is necessary to say a few words about safety measures. The fact is that the car has an ignition system with high-voltage (HV) wires, the voltage in which reaches 40 thousand V. In general, a small current will not cause serious harm, but it can still be dangerous. Therefore, when working with high-voltage wires, always wear rubber gloves or pliers with rubber handles.

Also, before turning on the ignition, be sure to put the Ford Focus 2 in neutral and raise the handbrake. After that, it is necessary to check the integrity of the explosive wires at the points of connection to the ignition coil, as well as its performance in general. The following situations may occur:

  • The ignition coil circuit is OK - you need to check if there is a spark in the spark plugs. To do this, remove the BB wire, insert a working spark plug into it and bring it to the car body (to ground), while turning the crankshaft. (The candle and the ground must have good contact, because with an increase in the spark gap, when it becomes wider than the distance between the electrodes, the motor control unit or the coil BB circuit may break). Such a check should be carried out no more than 5 s, otherwise the exhaust gas converter can be damaged.
  • Lack of spark - we replace the BB wires with new or just working ones.
  • No spark after installing new explosive wires - replace the ignition coil. If now a spark appears, but the Ford Focus 2 does not start, the problem may be in the candles that need to be replaced.
  • The lack of results after all the actions taken is a problem in the power supply and engine control system.

Supply system

If there is pressure in the fuel rail, then this means that the engine power system on the Ford Focus 2 is working properly. However, you first need to check the air filter and its condition, as this is done quickly and easily. If the air filter is in order, then it is necessary to check the connection of the electrical contacts in the wiring harnesses of the injection system units, which are responsible for supplying fuel.

The next step is to check the pressure in the fuel rail of the motor. However, in order to carry it out on your own, you need to have a special pressure gauge that can be connected to the fuel pipeline. To do this, we do the following:

  • We turn the ignition key and listen: if there is a slight noise, then the electric fuel pump is functioning. If it does not work, then you need to look at the power supply circuit of the gasoline pump.
  • We check the fuel pressure, which should be at the level of 3 kg / cm2. In this case, the engine must run at idle speed.

It should be noted that the petrol pump may not work if there is pressure in the fuel supply system. That is, if you activated the ignition in advance and tried to start the engine, then the pump should create pressure in the fuel supply system. Therefore, if in such a situation it does not work, then this is not considered a breakdown.

The lack of pressure, as a rule, occurs for the following reasons:

  1. Problems with .
  2. Damage to the fuel pressure regulator.
  3. Dirty fuel filter.
  4. Damage to the fuel pressure pulsation compensator.

You can find out the reasons why the engine does not start, either on your own or by contacting a service station for help. However, remember that if you do not have the necessary knowledge and skills, then you should not get into the Ford Focus 2 engine, as this can worsen the situation and aggravate the problem. In this case, it is better to trust specialists who will identify and fix the problem as soon as possible. Good luck!
