Hi everybody,

I just finished to pull out a turbo and NO2 setup as its going back to stock, and the car wont start on Oem computer.
It will start with starting fluid. Checked fuel pressure and i have fuel at the rail. Tried 2 oem computers with matching immobilizers so bad computer its excluded. The car runs on the aem.
I know its something electrical but im running out of ideas.
I assume the oem might use some sensors the aem doesnt. Please chime in

 

do you have access to scan tool.. check for codes.

 

No codes. Scanned all the computers

 

Yes. And we dint just take the turbo setup off, we swapped in a stock engine that was running fine off another s2k. Both ap1 one 2002 the other 2003.

 

Nobody?

 

Not sure how you expect people to diagnose your problem over the interwebs. It sounds like a lot of things changed.. Does the car have spark/fuel? Did you crank the engine and verify? That's step #1. If you want some more help you probably want to provide people with some more info. Was the harness modified at all, maybe a wire got cut? Could be a million different things..

 

do you have the aftermarket injectors still installed?

 

The car is STOCK at this point guys. No harness modification is needed with the Aem. Plug n play.
It starts on starting fluid, have 2 pulses at injectors when 1st cranking than nothing.
I know its hard to diagnostic but i know its electrical and there cant be too many things cutting the injectors, only need a lead

 

Immobilizer? Is it the original ECU that came with the car or the one from the swap car?

 

Ecu was reprogrammed by dealer to match immobilizer. By the dealer it is not the problem.
I am going to replace the crankshaft sensor see if that might do any change.

Thanks for the input
