93 lt1 into 94 3.4 wiring issues

I have a 93 six speed LT1 TA (wrecked) that I bought to transplant the driveline into my 94 3.4l auto Camaro. What do I have to do to get it to run and work with the 94 wiring inside the car? I don't care about nuetral safety switches or clutch switches so if there is a need or a way to bypass them that would be fine. Also , is there any other changes as far as fuel pumps or speedos are concerned that will have to be made? I can get the car to roll over but not run. I have fuel at the rails and 12 volts to the coil. If I put gas down the intake it will run off that but then dies. I have power to the injectors but no pulse signal to fire them, any ideas would be a big help

Re: 93 lt1 into 94 3.4

I am lost on this one so any help would really be appreciated. Is it possible that the six cylinder fuel pump isn't enough for the injectors, or is there a wire on the ecm that needs to be hot that maybe isn't do to the 94 wiring?

Re: 93 lt1 into 94 3.4

Come on guys someone has got to have some idea why I don't have any injector pulse from this car. I changed the pump still no pulse. I know it is fuel because it will run on fuel poured down the intake so it has spark. And check for power at the injector, it is there just no signalto fire them?
