I replaced the pump and am getting fuel all the way to the throttle body but truck wont start. if i add fuel directrly in throttle body will crank right up.

Throttle body injection? replace the injectors. First check for power to them. 12 volts from one of the wires with key on

when carb is wide open ????? No carb ,fuel injection ???? Are the injectors being controlled by the PCM / ECM ??? Have replaced fuel pump, fuel filter and fuel pump relay.???? Did you test first ?

Will it continue to run aftre you manually prime it? If so, you are lossing fuel pressure over time which may indicate a leak in a line and or a faulty fuel pump. (low pressure) Could also be a restriction in fuel line (filter) Frozen water in the line is not unheard of in cold climates.

I would check to see if you are getting power to the fuel pump. I would check the fuel pump fuse and relay if you aren't getting power to the pump. You may have got a defective fuel pump.

start with cleaning the injectors, check your secondary fuel filter, and vaccum lines

The fuel pump might be working but it is not priming. When you turn on the vehicle, the pump sends fuel under pressure to the injectors, to "prime" or have fuel present to be able to start engine. Without it there will no fuel available to start it. You are manually priming the engine, and the fuel pump is taking over from there. Check connections to fuel pump and replace if necessary. It is not an inexpensive repair

No, the fuel regulator from a 96 will not fit a 98. The 98 is a vortec and i believe the 96 is TBI. You are on the right track though, but the fuel regulator is attached to the fuel injector spider and is one unit inside the upper intake. It is relative easy to replace just takes some time.

ive got the same problem in my 87 chevy r10 from what ive read its the fuel pump i tried changing the throttle body, and the fuel injectors and it doesnt seem to be the problem im getting gas to the line but i dont think its enough pressure ill be changing the fuel pump and ill let you know.

There is an Idler valve near the intake that can be adjusted. that valve may be worn out and need replacing.
