Ok, I've narrowed my intermittent compressor to the speed sensor on the starter gear ring. I get twice the resistance and half the voltage as the thread suggests. I just can't believe it's bad since the compressor does work sometimes. Can anyone give me their thoughts. Otherwise, I'll just replace it. I just hate replacing parts if I'm not sure.

I do have a fuel leak between the #5 hard injection line and the injector pump I've been working on trying to stop but so far haven't been successful.

Could dirt and fuel grime cause this sensor to read incorrectly?
