I drive a 1993 F250, well I drove a F250 till last saturday when a small amount of smoke came from under the dash. The truck was running and suddenly quit running. I first tried to swap to the rear fuel tank, cranking away to no prevail. I then noticed the fuel pumps werent humming. though some deductive reasoning and a haynes manual the fuel pumps work when the test port is grounded. the inerta switch is only getting 6volts, I dont know if that is the correct voltage or not. Having trouble locating the EEC IV computer, also the dash seems to be stuck above the collum if any one has any helpful suggestions I would love to here them.
