I had a 91 firebird with a 305 and a camaro body that had a 2.8L in it. I swapped the motor and engine wiring harness and ecm from the firebird into the camaro body. This is the trouble. The car will Crank, but the injectors will not fire. There is fuel getting to them, just no pulse. There is power at the injectors on the hot side with the key on. I put the v6 ecm in it to see what would work, the injectors fired but the car wouldnt run. Im not sure if with the 5.0L ecm the passkey is an issue, if there is a way to bypass this or some other issue. Please help me out here. I wanna get this thing running. I will respond back to the thread when I can get back to the computer. Thanks in advance for any help.

 

Please Help me ... I am opening this up in the Electronic Wiring Forum Too.
