Post by: JoYneC on 19 May 2008, 22:28:51

hi all! i have a 96 omega that i hace swapped engine from x20xev to  x25xe.
when i had the engine out i changed the timing belt, headgaskets, dis pack, ht, spark plugs, crank sensor, maf sensor.

there is spark and the engine gets fuel but it just wont start  :-[

had it at vaushall dealer but they couldnt figure out whats wrong...

i may be way off here m8 but im assuming you changed the ecu and transponder and key chip so they all match

presumably, you changed the entire engine loom, too?

In these situations I think of "suck, squeeze, bang, blow"

For an engine to run, you need air, fuel, and spark on compression - you need to find which one you're lacking :D

I'll follow this with interest.

Have you any fault codes stored?

If you have compression, spark, fuel and "missfire" .. then its either igntion timing or valve timing.... I'd imagine the valve timing hasn't been touched .. so it's ignition timing .....

and the most common cause of problems there is wrong lead to wrong plug !!

so check from DIS pack to plugs to ensure you have the correct connections.... otherwise the spark is happening on an open cylinder !!

There might be a few that advise against this but a can of cold start from halfords will start just about anything.  I'd give it a try and see what happens, just spray a little in the air intake.

When you changed the cambelt did you use a locking kit?

I wonder if the cam timing is incorrect....bit of a long shot

didnt do it the first time.....but did it after i found out how sensitive a v6 was.....vauxhall checked it and said it was correct but i wonder if i have the cams 180degrees out så i will turn them this weekend an will see if it fires then ;)

I'd read the fault codes and see if the car will give you a clue...

Title: Re: Help needed!!
Post by: JoYneC on 22 May 2008, 17:00:43

tried turning the cams 180deegres but didnt help.....no faultcodes found  :-[

Title: Re: Help needed!!
Post by: rickyboy on 22 May 2008, 18:00:13

Any possibility it could be the crank sensor - doesn't the 6 pot need the engine running to log a fault?  

Title: Re: Help needed!!
Post by: JoYneC on 22 May 2008, 21:10:15

have changed the crank sensor so its brand new...

When you changed the timingbelt, was all the sprockets aligned with their marks? Sounds like the timing is incorrect.

I did the same once, just a few teeth wrong, and it would't start.
