SOURCE: Fuel pump
Not a simple problem, the fuel pump has most likely burned up. The pump uses the gas to keep it cool, and will continue to run until it has built up the correct pressure.

just because injector test ok electricly that doesnt mean its working right if the tip is plugged instead of sprayying a fine ignitable mist of gas it just drips out if this happens the gas wont ignite and you get a wet plug. you can switch injectors from one cylinder to anther or you can just replace #7 let me know how you make out with this

The fuel pressure should be 60 to 65psi in your system with the engine not running and fuel line primed, (ignition key's to the run position). Once engine is running the fuel pressure should drop by 5psi, change the fuel filter and recheck the fuel pressure at the shredder valve. it's known for the fuel pump to fail when the gas tank runs low or out of gas, the pump will end up burning it self out since the gas is what keeps the electric fuel pump cooled. The other thing to is putting gas through the top of the throttle body to start the engine on the SEFI is a NO NO, well a BIG NO NO. it's been know for the gas in the intake to catch fire and burn up the poppet valve in the injection system causing the replacement of the fuel injection system. Keep me posted and good luck, be gald to help you get your truck running again for the july 4th. OH and it was not mentioned but did the fuel filter get replaced???

there should be 2 power and 2 grounds. gray is for the gas gauge, power all the time. purple is fuel pump power, you need another person to cycle the key while you test it with a voltmeter. it will show battery volt and then drop to zero. that means that the relay is working. make sure that the black is on the black lead of the volt meter. test both blacks to see if your losing a ground. the main ground for the pump is on the frame near the tank. test these first and let us know what happens. best of luck

Car not starting or turning over indicates towards multiple possibilities.
It can be issue with battery or weak battery. But if battery checks out ok, then
it can be starter issue or faulty alternator or problem with low fuel pressure
or no spark at spark plugs due to dirty spark plugs or faulty
ignition coil or injectors getting cracked or dirty and needs to be cleaned.
To confirm the problem, the basic troubleshooting is required.
