Misfire
« on: 03 February 2018, 17:08:51 »

Over the last couple of weeks our 2.2 diesel omega (2002) has become un-driveable and the exhaust emission light has come on. This is only when my wife has been driving it so she has lost confidence in the car she called the AA the first time it played up she said it would not start at all I got to the car before the AA and was able to drive it the mile home but the AA still came to our home  and checked for fault codes which there were done.

It ran fine when I was driving blamed her driving but it finally did it when I was driving it misfired a couple of time the warning light came on for a few seconds then it seemed to settle down again drove fine.

What could be causing the problem?

This may be a silly question, but where do you buy your Derv?

If EML comes on, there should be a code...

It finally died with me driving the car left home it hesitated a couple of time then died then would not restart it then restarted went a couple of hundred yards then dies again and got it restarted did that 3 times until it completely wont start at all. Left for about 20 minutes while waiting for AA before they came got it to start and took it the 400 yards back home. When it was playing up it was very smokey.

Think it sorted now this is the report from the AA.

Patrol found the following fault code/s:System : Engine control - 73L / Diesel EDC 15C4P1220 - Unknown fault. Error Message : .P1345 - Unknown fault. Error Message : .find crank sensor multiplug had water ingress, clean, ok.

Water in the multiplug for the crankshaft sensor hope it fixed now.

Sorry to hear about your bad luck.  I hope you manage to sort it.  My 2.2 petrol kept missfiring and playing up, I changed cam and crankshaft sensors, coil pack and new plugs. It ran great for a while but started playing up again, my error code again was for the camshaft sensor. I lost all confidence in it as unknown when it would play up, so have bit the bullet and scrapped it, got a 2.6 now.

Not necessarily.

Something in the back of my memory says fuel flow problem which is caused by a blockage due to crud at the tank pick up. You can disconnect the pipes to the fuel chamber under the back seat and blow back down them. You should hear the air bubbling in the tank. As these pipes are prone to rust there's a source for blockage along with any sediment that might have been picked up if the tank ran a little low.

Is there a pump in the fuel tank or does it rely on the pump on the engine to draw fuel from the tank.

Taken up the cover in the boot to expose the fuel tank 2 pipes going to it but will look again the daylight.

Its a shame to scrap the car but not going a spend a grand on it nor worth for a car that 16 years old.

There is a pump there, and I think there may be an additional strainer to stop bigger bits of crud from passing through the pump. Not certain about this second bit as I've never had to take mine apart.

I'm pretty sure the Dti does not have an intank fuel pump,fuel is drawn by the main pump at the engine :y

Sorry, my mistake, I was working off the parts catalogue - mine is currently not in a position to be dismantled to check. 2.5 DTi has a pump, 2.2 DTi does not. but there should still be a strainer assembly to get blocked and pipes to and from the tank as well.

Tried to start it this morning just turned over came home from work mid afternoon and got it to start left it ticking over when we rang a garage we have used in the past drove it the 2 miles to them with no problem they are now going to see if they think its the pump has gone as well.

Will scrap it if it is the pump, only cost us 240 5 years ago 16 years old now with 140,000 on the clock. :'(
