My First start is so close I can taste it but the engine won’t fire. I’m using a dieted EFI harness on my 347. I have fuel cycling and returning to the tank each time I turn the key. I tested the coil and have spark. I pulled the distributor turned it by hand with spark plug off the coil and I have spark there completing circuit. What I don’t hear is the injectors firing. I’m going to get a code reader tomorrow any ideas ?
