Hello everyone. New to the forum. I recently bought a 92 GMC Vandura 2500 (350 TBI) and it has a start stall/crank no start. If i give some throttle, it will start and idle. Intermittently, i can press the throttle, and the throttle body will make a harsh buzzing sound. I cannpt figure out what is causing it.

I also am showong 0psi of fuel pressure...with the engine running. I know, i thought it was a gauge too. Ive tried three... all show 0psi. Ive changed the pump, and the regulator. I can hear the pump running.

If anyone could help me with these two issues, id be very grateful.

Thanks,


-Tim
