Got my swap running pretty good, except for a dead miss on cylinder 4. I checked and #4 injector isn't firing. So I thought I'd switch it and all would be well. That was not the case, still not firing. I checked it by taking the injector harness off and cycling injector #4 with a 9v battery and it will click. I've checked voltage on both sides of it when the key is in position 2 and get 12 v on both sides so I know the connection between the injector and harness is good. I've also checked the resistance of all of them and there all the same. ~16 ohms on a warm motor. Then I checked all of the injector signal wires to the computer connector and they are all good. So I'm at a loss, what can cause the computer to not fire the injector? I did have a missing ground on the ignition coils when I first got it wired up. I'm wondering if I fried the computer? I also had c104 miss wired not sure if that could have messed with it. Other than the injector not firing it runs great.
Any ideas?
