Hello All -
I got a question the local Ford dealers can't answer, three different dealers = three different answers.
1995 Explorer Question. If you don't crank the engine the but leave the switch on, the fuel pump will stop after 2-3 seconds (normal condition). What terminates pump? Is it a timed event controlled by the PCM or is the PCM responding to a pressure transducer or some other event? This is not a relay question, I realize the relay starts and stops the pump, but under what condition does the PCM send the off command to the relay?thanks don
