if the engine turns over, but just doesn't start, you need to do some checking, check for spark from the coil, or coil packs, if that checks out ok, have the crank and cam shaft position sensors checked, timing belt, computor. I know it's a pain, but I have worked on cars for 40 years, something like this you have to use process of elimination, without testing, you could replace things you don't need. ( expensive) good luck).

If you remove the line just prior to the carberator or the fuel injection line then turn the key on you should get a flow of gas.
Any time you are working with open fuel and fumes it is dangerous so make sure the area you are working in is well ventilated.

Apollo, I would first pull all the plugs out and give a little squirt of something like seafoam or even just a bit of engine oil into each cylinder, you may have lost the seal between the rings and cylinder walls and this will help. You also need to confim for shure that you are not getting fuel before you worry about the pump. You can check this at the fuel rail, either by opening up the line, or in some cases you may even have a schrader vale(like a tire valve) on the line that you can press. I suspect that you do have fuel, but the injectors are not oppening due to the old fuel sitting in them for so long. These can be removed and taken to a shop that cleans injectors, and then reinstalled with new seals. And yes I do belive that there is a fuel pump relay in the fuse area, you need to do a search to find out wich one. These can be jumpered to activate, but untill you have done everything else i wouldn't worry about it. Oh, I asume that you have checked for spark? If not, you can pull a plug out and with the wire attached you can hold the base of the plug against the block, while wearing gloves, and see if you get a spark when some one cranks it over. Remember, you must have spark, compression and fuel at the right time in the proper ammount, and it will run.

Testimonial: " He knows what he is talking about. Great suggestions, thanks"
A FORD EQUIPED WITH DUAL TANKS THIS YEAR MODEL HAS CHECK VALVES IN THE FUEL PUMPS .THE FUEL RUNS FROM THE REAR TANK WHEN IT IS POWERED ON TO A TEE AND INTO THE SAME LINE AS THE FRONT PUMP . THE PROBLEM IS AT THE BOTTOM OF THE FRONT FUEL PUMP THERE IS A CHECK VALVE ON THE FOOT AND IT IS NOT WORKING.WHILE THE TRUCK IS RUNNING WITH THE REAR FUEL PUMP ON IT IS PUMPING FUEL INTO THE FRONT TANK . IT WILL RUN OUT OF THE NECK WHEN IT IS FULL.THE FIX IS SIMPLE REPLACE THE FRONT FUEL PUMP. THEY DONT MAKE A CHECK VALVE REPLACEMENT I CHECKED I HAD THE SAME PROBLEM AS YOU.

Unbolt the bed bolts, remove the tailgate, unplug the light harness, and unbolt the fuel filler where it bolts to the bedside and get a couple of buddies to lift off the bed. That way you don't have to drop or drain the tank. It's much faster, on my truck it's only four bolts and the bed is not that heavy.
