Maybe you need to get a new fuel pump.
prob have a bad ignition switch
The fuel pump reset switch is on the driver's side kick panel.
If you hear the fuel pump run that is a good sign it is working however, a fuel pump pressure test would tell you if the pump is meeting the required pressure.
I have the exact same problem. After replacing the fuel pump everything was fine. Now the fuel pump does not always kick on and you have to turn the ignition on and off until you hear the fuel pump kick in. Went to start this morning and fuel pump did not kick in, still wont. So I checked the relays, all good. Now the fuel pump kicks on but it still wont start. Did the computer on this thing die?
AnswerTells the fuel pump when to kick on and off. The relay has a coil and contacts, when energized, it holds the contact closed, thus the fuel pump operates.
FOR TESTING PURPOSES ONLY you can jump the fuel pump relay to operate the fuel pump. If the pump is not running, knowing GM fuel pumps, it is probably a faulty fuel pump.
Check the fuses and relays.
Can't say for sure that this is your problem.....but a lot of the GM vehicles run the electric fuel pump through the oil pressure sending unit. If it doesn't sense any oil pressure it won't allow the fuel pump to kick on. This might be one area to check.
The fuel pump relay is located on the driver side, under dash mounted behind kick panel. Fuel pump is mounted on top and inside the fuel tank.
Check the fuel pump relay.
No. The fuel pump is what pushes the fuel into the cylinders. If you have no fuel coming into the engine, it won't run no matter what you do.
The fuel pump inertia switch is in the right front passenger footwell , by the kick panel
