78skylark

Just put an ls1 from a 98-02 Camaro in my 78 skylark engine has ls6 heads and a bigger cam bought off ebay a few years ago and ecm was supposedly set up for a swap in an older car, also has a new wiring harness from painless. The engine fired the first couple times but died as quick as it fired pulled a plug from each side and they had spark while cranking also were a little wet with fuel, got 60 psi fuel pressure while cranking, also maybe sounds like its backfiring through the intake, not sure if its sensors or what just looking for suggestions.
