Fule injectors not working right and no spark

[Kurtmarshall]

Hey guys I have a 1994 vr commodore and I have removed the 3.8 L Buick and put in a 3.8L ecotec I am using the loom and ecu of the Buick on the ecotec witch run the same crank angle sensor but it has no spark and the injectors were not working when I first tried to start it but after I put a test light in the plug there was no power but after I put the plug back on they started working when I only had the ignition on not trying to start the motor anyone know why??

Conversions are tricky at the best of times. You'll have to check over your wiring to ensure everything is connected properly. Sounds like you need to compare wiring diagrams for possibly a missing sensor.

Use a manual for the diagnosic process for testing.
