Fuel Pump Specs


Recommended Posts

Posted

As mentioned before,my truck has been hard starting the last few days. I put a fuel pressure gauge on it, and when I turn the ignition to ON, the pump brings it up to 60 but as soon as the pump shuts off, the pressure drops down below 40 and continues to drop. If the truck actually starts, it runs at about 52 psi. I believe the spec is 60-66psi all the time, so the pump must need replacement. This is all after the fuel pressure regulator has been changed, so it must be the pump, correct?
