88Fuel Pump
Trying to fix my daughters truck. I'm not getting any fuel to the fuel rail. I've replaced the fuel pump relay. Does anyone know how to determine if the low pressure fuel pump in the gas tank is bad or if the high pressure pump attached to the frame is bad?

Welcome to FTE!!
You should be able to hear them run for a few seconds when you first turn the key on. If you have a problem hearing the intank pump because of the one on the frame disconnect it and listen again.
