1993 Ford Tempo 4 cyl Front Wheel Drive Automatic
changed ccrm (fuel pump relay), engine computer, check coolant temp sensor and in specs range. The fuel pump will have a great chance to prime (2-3 sec) when the key is on when engine is cold but when it`s hot, I can't hear the fuel pump buzzing at all.
What are the diagnostic steps I can do to isolate the issu?
Is there a way to provide 12 volt to the fuel pump to test it out and not having to remove it in the tank?
have the same problem?
