Title: start problems
Post by: vladcaravan on 04 November 2010, 14:35:41

Hy i have a 2003 omega 2.2 dti,and i have a problem starting the engine:at the first start of the day(morning)sometimes after it fires it will not accelerate and die.After this i have to crank the engine for about 10-20 seconds,after it will start and black smoke comes out the exhaust,and it will not stay at idle without me pressing a little on the accelerator.I found that if i park the car with it's front down(rear up on a hill) it will start with no problems.I forgot to say that i went to a dealer where they checked the car on a TESTER and no codes appeared.Please help.

Bad starting on a deisel usually points to Glow plugs, but once started should run. I would be checking fuel pump, has car been serviced recently, dirty oil can cause black smoke, fuel cleaner sometimes helps, keep us posted and someone will help you more than I can.

Sounds like you have a leak in one of the fuel pipes, fuel bleed off pipes or fuel filter which is allowing the diesel to run back to the tank which is a common problem on the desmond diesel due to it only having an injector pump. Have a look at the injectors there will be pipes linking each one, if the pipe is covered in like a cloth its probably original and I would start by replacing that ;)

i agree with elite pete,
i have a 2.2dti saloon elite and suffer from the same problem,
check leak off pipes and injector seals as they wear, air is definately entering the system some where, i have pondered on how to remedy the problem myself and after changing the above am considering putting a non return valve in the fuel line  next to injector pump to STOP the fuel from returning to the tank, i thought to myself and tried parking on a hill nose down and the fuel still drained to the tank and could only start it with easy start, the 2.2dti engine can be a complete bar steward belive me! get codes read by a tech 2 and see if there are any problems with the pump , a   word of warning the pump can be VERY expensive to replace or even fix. :o
