Whatcani do no power to fuel pump

Is the relay sending power out to the pump? Is the ECU sending the signal to the relay?

Does it have battery voltage from the fuel pump relay ? Do you know how to check automotive electrical circuits ? Viewing a wiring diagram an using a DVOM - digital volt ohmmeter to test is the proper way to see why it doesn't work . Your best bet mite be to have a qualified repair shop check it out . The fuel pump relay is controlled by the PCM - engine computer .

One guy I know traced it to his in-tank fuel pump. The computer reads that all of the electronic components of the pump are running at optimal, but a pressure gauge connected to the fuel rail on the intake showed the pressure was 58 psi at an idle and it dropped to 45@ 2000 rpm's. 58 psi is minimal for a big block, 60 is optimal. The book shows the small block should be around 50 to 55 psi for optimal pressure. The drop in fuel pressure causes the engine to lean out under a load such as accelerating and pulling and could cause the engine to burn a piston from the increased cylinder temp. I am not certain how this would cause ignition power loss though, unless that fuel pump has a safety cut out for electrical shorts, real or perceived by the computer.... Have to talk to some friends about that.

You need to buy or borrow a voltohm meter and check fuses for voltage and trace the voltage to the fuel pump.

Has the fuel pump relay been tested? Be aware the pump only runs when the engine is being cranked over with the starter.

check the crankshaft position sensor

Have you checked the fuse/relay or the reset button (if equipped)?

he was hooking a hot wire to the fuel pump. hes right your loosing power somewhere in the power supply to the fuel pump. it needs to be traced down to see where the power loss is. the short or loss of power could be anywhere in the line. hope this helps

Please this is a fuel system related problem.

Check the fuel pump located in the fuel tank beneath the back seat.

The fuel pump has dropped in pressure.

Good luck dear.

check your trunk for an emergency shut off button for fuel pump its usually a black littile box on the side with a red reset button in it
