 I posted awhile back about not getting fuel to the throttle body during start up. I can get it fired up with starting fluid. Ive replaced the fuel pump twice thinking I may of got a weak fuel pump. Also replaced fuel filter. When it fires up I get fuel to the throttle body and itll run forever. Its putting out a nice cone, but will also throw drops in middle of the cone here in there. Any guesses? And I dont have the extra $100 to "rent" a pressure gauge at Auto Zone.... Thanks fellas.

Fuel pump relay most likely- the fuel pump circuit feeds through the oil sending unit also. Once its running and builds oil pressure it completes the circuit to the fuel pump. The relay is mounted on the pass. side firewall behind the black cover. There is also a fuse there too. check that.

I don't have a whole lot of experience with the bow ties but if I was to venture a guess I doubt it would be the injectors since it seems to run ok when it gets started. Would lean more toward the f/p reg or solenoid fuel pump control. It certainly going to be more difficult to diagnos without a guage to test the fuel pressure prior to start with ignition on only. After it sets a couple of hours can you hear the fuel pump come on when you first turn on the ignition prior to attempting to start?

If I remember correctly, the harness connector on top of the fuel pump had issues. Seen them burnt, they sell the repair kit for it. Might want to check there.

Hmmm. Went to start mytruck a few minutes ago (2002 Chevy Silverado) and it started, but immediately started to idle rough, then died. It started a couple more times but almost died immediately, sounds like it is starving for fuel. Tow truck headed here now to take it in for repair. Hope this doesn't break the bank...
