Have you checked and triple checked the PCM's wiring harness plugs for bent pins?

I thought the car had to have the correct VIN on the PCM, so the BCM would agree and then the car could start... not sure though.

yea thats what i am worried about,what would happen if i put my stock computer back in with the bigger injectors? or can i send a computer to intense and get one back that will work? thanks spooner

You computer will handle the larger injectors ok, I drove for days like that. I'm not positive that's the case though, in terms of the PCM/BCM thing. Have to get that verified by someone like Wop or someone else that's tried. I could sware Rice told me he tried it on his car and it worked, so...

ok ill wait to see what u find out? should i put my computer back in it till then,there is no saturn dealer close to me,or i could have it flashed i guess.i really wanted to see how it would run scince i have a 04 that has never been touched at all till now and look what happend

I'm pretty sure you have to do that security relearn procedure in order to get it to work. This is what I was afraid of w/ the "write entire"

does the battery have a good connection?

not trying to be funny or anything sometimes we over look the smallest thing thats all.

yea every thing comes on like it is going to start but nothing happens,i put my computer back in and it cranked right up,whats the case re-learn thing

I tried a different PCM in my car once and didn't have any issues other than a few codes (which I cleared). Drove it around for awhile and it worked fine. I would guess that if you try a PCM from a different year car, than you would have problems. Especially if your car is a 2004 and you throw in a 2005 PCM with the Stage 2 calibration for an '05. Probably won't work very well.
