In the past I have seen fuel pumps that would run on the bench but wouldn't work in the gas tank. Sometimes you can bang on the gas tank and get the pump to start working, the problem is usually bad brushes. In the past I have cut open an electric fuel pump, those little brushes were wore down to the nub.
If you have good voltage and ground at the fuel pump and no pump action, suspect the fuel pump. Fuel filter is good, I didn't look to see if inline fuel filter? Fuel lines aren't clogged? Don't disconnect any fuel lines unless your sure, no fuel pressure.
next time u go to start it in the am get in the truck and turn
the key to on and listen for the fuel pump turning on
for about 2 seconds if not before u go to replace the fuel
pump replace the fuel pump relay in the underhood fuse
panel common problem good luck lets hope for a cheep fix
Replace the fuel filter to help the fuel pump, but it sounds like the fuel pump check valve has gone bad and your losing your fuel pressure to start the engine. Your going to have to keep priming the fuel system by turning the ignition key to the run position for 5 seconds 3 times before you try to start the engine. The only fix for this is to replace the fuel pump, and that is costly. Good luck and take note: the fuel pump has a life time of around 150,000 miles and anything past that is borrowed time.
Time to replace the fuel filter. It's not a hard job actually. And it's a VERY common thing to go wrong. I'd change the fuel filter and then run some fuel treatment through the tank afterwards. Believe it or not, I've noticed that a nice bottle of fuel treatment really conditions a fuel filter well.
