Re: problem with fuel pump
I'm not very familiar with these vehicles, but usually the relay box is near the battery at the hood compartment. Worst case scenario, the car has a short and the fuel pump is not receiving the adequate current to function properly. You will then need to run a test in order to find the short, if any and repair as needed.

are you shure the pump is working,? Take the fuel line off,To see if there is fuel comeing up to the engine, When you have it off kick it over quicky to see if fuel is comeing out of the line, If not the fuel pump regulator might be at falt, Or the fuel pump it self has gave up the (Goat) end quit working,
Do this test first. With the drivers door opened in a nice quite area turn the ignition key to the ON position without starting the engine. You should hear the fuel pump operating for 5 seconds which is priming fuel to the engine. If not heard the engines oil pressure sensor is at fault. The third wire from this sensor links to the fuel pump to prime. When the engine reaches normal operation oil pressure range the computer shuts off that circuit and turns on the fuel pump relay for the pump to run. That relay stays on until you shut the engine off
Jim; have you confirm the fuel pum[ is working? If it is, you should get something out of the fuel rail. Sadly. Pump is a dealer recommended repair cause the pump is more than likely in the fuel tank. Thry should changre you filter at the same time.
Was there fuel pressure before you changed everything? It could also be the pressure regulator sticking or bad. When you crank it over and let off the key you should hear the fuel pump run for a couple seconds and then shut off. If it is doing that then I would be looking to see if you have likes hooked up wrong at the back of the engine or try replacing the pressure regulator.
Try the ignition control module located under the distributor cap $30 - $60. This is one of two parts on this truck that will cause it to not run or shut down after running for only a short time. The other is the fuel pump I think it is safe to rule that out as your problem
