If youare looking for fuel at the throttle body, you will not find any unless there is something TERRIBLY WRONG with your truck. Depending on which engine you have (there are 3 possible engines for the 1996 model year) your truck is equipped with Multiport Fuel Injection (MFI) or Sequential Multiport Fuel Injection (SMFI)
You need to test the fuel pressure by connecting a fuel pressure gauge to the service port on the fuel rail. If the pump is running, there is no need to mess with the relay because it is obviously working. If the pressure is OK, then there is no problem with your fuel delivery system. The next thing to check is the fuel injection system. Also, have you checked to see if you have spark at the spark plugs? It could be that your truck is not starting because of ignition system problems.

fuel filter or a fuel pump could also be plugs, wires, cap and rotor I would try fuel filter first then take a plug off a cylinder and hold it close to screw driver or something(dont hold unless have rubber to grip to please dont get shocked) if it doesnt spark your not getting spark and try plugs wires cap and rotor if it does spark then open gas lid have someone turn ignition switch on and listen if you here the fuel pump is still good if not replace it. It does sound like a fuel pump

My 2000 kia sportage is having fuel pump problems sometimes the fuel pump doesnt pump at all. ive checked the ground on the fuel pump, the fuse is good, and i dont know if theres a fuel cut off switch....

it sounds like the problem is the pump will probably have to have the pump replaced to correct the problem.this is how a bad pump acts when its worn out and needs replacing.replace the fuel filter at the same time

The engine rotates but will not start

You may have gotten a defective replacement fuel pump. I would check the ground for the fuel pump, but it seems there's not much left to check.

This is a fuel system related problem.

Check the fuel pump and I bet you will need to replace it.

The fuel pump is located in the fuel tank and can be reached by removing the back seat.

Be careful when you are disconnecting all connectors and watch out for the pressure of the fuel pump.

Good luck.

98 GMC starting problems

Take off your gas cap and have someone stand there with thier ear at the hole, (no smoking), turn the key to on just before start and they should hear the fuel pump humming. if they dont then try to start. if it doesnt start turn key off and at that instant the pump should be heard again. What i think is happening is your pump is not energizing . Its supposed to energize when turning your key on and off. This can be caused by a bad fuel pump or pump relay switch. Hope this helps. please rate me
