Finishing wiring help ls1 swap Ok so my car is wired up its a 1987 notchback and i went to turn it over and only the first cyl is firing. All the injectors are working properly. The pcm has a start up tune that we put in it but it is just puzzling to me why this isnt working. It will crank and crank and crank then it will backfire. Every plug is fine but the number one. The number one is black. Any ideas?
