97 Ford F150 4.2 Fuel Pump Primes but won't start.
I have a 97 F-150 4.2 V6. The trucks fuel pump will prime when key is turned
to on, but as soon as you turn the key to start the fuel pump stops. I have
replace the fuel pump, fuel pump strainer, fuel filter. I have also checked the
relays. The fuel rail pressurizes when in prime but stops during cranking. The
truck will start with starting fluid. I have also checked the interia switch.
