I am having problems starting my truck. We have tried to change the fuel filter but it is still not starting. It will start for a few seconds if we add gas directly to the carburetor. The fuse is not blown, we checked that, the next thing we can think is the fuel pump, but we know neither where it would be or how to tell if it is working. Please Help!!!! Thank you.

The fuel pump is in the tank. On the 1996 model, it is required 50 p.s.i. to start the engine. even if you hear a "buzzing noise", the pump may still be bad. if it is not producing enough volume, or pressure. also check the fuel pump relay. it is located under the hood in a fuse/relay panel. look at the fuse/relay legend to find the relay. have someone turn the key on if the relay "clicks" it is generally good. second find the wiring harness that goes to the tank, under the truck, on the frame rail, thee will be a gray wire in that harness. probe that wire with a test light and have someone switch the key on again, the test light should burn for about 3 seconds, that will tell you that the fuel pump is getting power and the fuel pump is bad. drop the tank and replace the pump. all though, quite costly, as it only comes as a complete unit, it is the only way to fix your truck.

The fuel pump assembly is located inside of the fuel tank. The tank will have to be removed for service of the pump. A way to check for low fuel pressure is to turn the ignition key on and off 2 to 3 times to prime the fuel rail then see if it will start. You should here a buzzing every time you turn the key on. If not then either the pump has failed completely or more likely has a broken wire in the harness on top of the tank.

The fuel pump is in the gas tank. The entire tank will have to be removed and then the fuel pump assembly can be removed. But before you do that: The easiest test is to put a fuel pressure guage on the fuel rail and see if the fuel pump can achieve about 45 PSI of pressure, that is what is required to start these vehicles.

it's at the front on which ever side the gas cap is. outside the tank before you get to the rear or front seat. (Dual Or Single Cab.)
raise up from the bottom of the vehicle about 6 inches.
When You Fill Up, The Fuel Should Be Alot Colder that the fuel already going throught the line, just after you fill, go to the side and have the car idling and if the fuel line is getting colder rather quickly, and/or the pump is gently wibrating, then it should be working fine.

You are correct if spray starting fluid into the throttle body and is running 9 times out of ten it is the fuel pump it is located in the fuel tank and will take you about an 11/2 hrs to fix drop the tank and it is on the top

It is in the gas tank your truck needs 50 pounds of pressure in the fuel system to start. The fuel pump is a common problem on that model truck so I would bet that is the problem. I hope you don't have the tank to full it is a pain to drop the tank when it's full.
PS don't even think about smoking while you are replacing the pump.

It is probably inside the gas tank, to see if it is working merely take the fuel line off the injector(I'm assuming it's fuel injected) and turn the motor over while someone holds the line over a bucket, if it shoots gas into it then your fuel pump is fine

Probably mounted on the tank.
Take of the fuel line and see if fuel comes out, also check for a clogged filter.
