Engine won't restart
Engine won't restart
Help! I put an new engine in my exa and had it running but really rough... I tried a spare computer that I had and the thing wouldn't start, I put the old computer back in but it still won't start.
I checked fuel out of the FPR it was fine, checked spark leads and they were firing, checked injector plugs and they were firing too! I don't know what to do next?
Could it be whole water temp sensor thing? Bad fuel/over fueling? Do I have to reset the computer?
Anything will help guys...

cheers Michael,
have you checked for spark and fuel?
My old exa I created from granny spec to a neat little BRIGHT car: http://forum.n12turbo.com/viewtopic.php?t=3903

Baz... Yes!
Blue I checked the AFM and changed it with a spare and no difference. I literally had the car running 30 seconds before I swapped the computer and then it just wouldn't start...
Is it because I didn't disconnect the battery when I swapped the computer? could the be a problem?
E won't happen cause I had it running and I've numbered my leads too. I'm sure it's something so simple that I just can't figure out... but what...

was the ignition on? (still very unlikely...)txateu wrote:Is it because I didn't disconnect the battery when I swapped the computer? could the be a problem?
did you run a self-diag test?
its quite a stretch, but happened to me once:
take out the spark plugs (look for abnormalities on them) and give them a good clean or put new ones in....
good luck

Re: Engine won't restart
Thats why I suggested the plug leads. You didnt say you had it running smooth. See above.txateu wrote:Help! I put an new engine in my exa and had it running but really rough... ...

I bought a new set of plugs so I'll fit them and let you know. Nah the leads are fine... it was pretty smooth on idle but it rev'd up really rough like it was running on 3 cylinders
Boosted I don't want to sound like an idiot but how do I self diagnose the comp? It's my first exa if you can tell...

Update I haven't had a chance to do the diagnostics but I tried a new set of spark plugs and a little startyabastard and the car started first shot...
I ran the car for about 10 minutes and gave it a light rev then turned it off and tried to start it and it was no good... I could smell petrol (no exhaust on the car) so I'm thinking that it's running way too rich and has flooded the cylinders at least I hope so... I don't have an oxy sensor on the car so I'm assuming that this could help but I really have no idea
I'll try the diagnostics when the rains stop

Sounds like what I'm going through at the moment. Mine is rich and won't start when engine has some temperature in it. It starts when cold. It's probably going to turn out to be temp sensor or wiring or AFM.
Does anyone know whether there is any form of temp sensor in the AFM itself?

Hmm well I don't have a log on this engine so I don't know what to do it its the temp sensor, I have a spare AFM so I'll try that firstPaul Smith wrote:Sounds like what I'm going through at the moment.
