start problems

I recently put a 355 motor in my 95 formula. The car spins over but wont start. I looked for the cause and the injectors are not firing. I checked with a noid light to make sure. I checked all the grounds and they are all present and they are good and they are. I had the VATS deleted and thats the only thing else that i can think of that would make the injectors not fire. Bryan with pcmforless.com is trying to help me out but so far we havent come up with anything. Im stuck and I wanted to know if anyone has had the same problem and what to do to fix it. I dont think the fact of it being a 96 motor and A4 tranny make any difference. The pcm worked before and I even tried another computer and same thing. Please help. Thanks, Bill

Re: start problems

Have you scanned it for codes? Loss of low res pulse from the Opti will shut down the injectors and the fuel pump.

No I havent scanned it. The fuel pump turns on but would it for some reason not work if the case is what you said it could be? bill

Re: start problems

There is quite a bit of difference between a 95 harness and 96 engine. Just a stupid question here, is there 12 volts at the injectors?????? Did you check the 2 injector fuses?????
