I need help I have completed my first LS1 swap to a 69 firebird. Had it fired up and running smooth.
All grounds are installed. I went out to start it up for a buddy and it ran for a few seconds then coughed, backfired, and died. I checked fuses and found bad fuse at 12V to pcm. So I replaced fuse but it still wont start. Fuel pump is fine and I replaced crank position sensor. still no start and Im not getting spark. Anybody have any ideas? thanks
