The number one cylinder isn't firing. I swapped ignition coils with a working one and it still didn't fire. I swapped a spark plug with a working one and it still doesn't fire.
I unplugged the coil and with the engine running I probed the electrical connector and got 14 volts to the red wire and 14 volts to the black wire, I don't know what the middle wire is for or what it's suppose to read for voltage.
So I think the coil is good and it's getting power and I think the spark plug is good. What else do I check for???
