I have a 91 jeep cherokee 6cyl 4.0l,
it stalled when the car warmed up. I replace the fuel filter, blew out the lines, and cleaned the fuel injectors and fuel rail. It ran, but would stall after it warmed up. So I replaced the fuel pump, then I didn't get any fuel to the engine or in the lines, so I exchanged the fuel pump. II re installed foe the third time and still nothing. If the pump wires were wrong would you hear the pump? What did I do wrong or is it something I'm not thinking of?

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
