Question about 1998 Chevrolet K3500
A few suggestions:
Check the air intake and see if it is dirty, plugged air filter. you can clean with a good air intake cleaner...follow instructions on the can.Those years were noted for problems in the dist cap. check it for cracks.
Check the pressure regulator it is on the left side fuel rail on the engine.
I would for sure test it before just replacing it. Test it with a fuel pressure tester.
Dirty injectors could do the same thing.
Low pressure could also be from a worn pump.
