i got my car running tonight but its only running on 3 cylinders, my 3rd injector is not working i tested the wires and all the primary wires which are yellow and black and they all have power when the cars on accessory and whens the cars on.

But the other wire that goes into each injector they have power only when the cars turned on, But the blue wire on injector 3 does not, i ran a new wire from the injector to the ecu and it still does not get power or work. Any ideas? Thanks

 

Bad ECU?

 

thats what im thinking, car starts and everything tho, im getting error 15: Ignition output signal

 

Do you have another that you can try? Have you checked the ECU harness plugs?

 

fixed, it was the pin pushed over on the injector, thanks Dogginator for helping tho
