I have a 1993 Chevy 1500 Silverado 5.7 worked. I changed the feul pump and feul filter. When you turn the ignition to the on position you do not hear the feul pump engage and there is no feul pressure at the filter. I checked the feul pump fuse it is good was wondering if it could be the feul pump relay on the firewall or any other ideas you may have. I am begining to get frustrated. Thanks

Place a piece of black electrical tape over it ,problem solved .you know the oil is good

This sounds llike weak feul pressure, the fuelpump may need replacing, the first thing to do is have the fuel pressure tested and if the pressure is low then have the pump replaced. the pump is located inside the fuel tank and the tank will need to be dropped to replace the pump, good luck ,

It sounds like your injectors are not firing which could be a crank signal problem or wiring,distributor pickup coil problem or a computer problem.One wire to your injector should be pink this is the power wire it should have around 11.5-12 volts with the key on. The other wire is ground that the computer uses to fire the injector which you can check with a good test light hooked to voltage. and work back from that point if you have neither at the injector.

It sounds like the fuel pressure check valve on the fuel pump has gone bad and your losing fuel pressure when engine is turned off. Try priming the fuel pressure twice, that's when you turn the ignition keys to the run position with out starting the engine for 10 seconds and then turning the key's to the off position and on again for 5 seconds. After the second prim the engine should start, to check this you can lone out a fuel pressure gauge and check the fuel pressure at the shredder valve. You should have 62 to 65 PSI during prim and once the engine is running, it should drop by 5 psi. As for your the accuracy on reading the right amount of fuel in your gas tank, the sensor is apart of the fuel pump sending unit and the float may have gotten bent and nothing you can do to fix it unless you take the fuel pump out again and replace the sending unit. Good luck and keep me posted.

Check the fuel pump relay. Refer to the owners manual for it's location.

Turn the ignition key to the RUN position. Fully push and release the accelerator pedal 3 times within 5 seconds. If the CHANGE OIL SOON light flashes 2 times, the system is reset. However if the light comes on and stays on for 5 seconds, the system did not reset. Repeat the procedure if the system does not reset.
Best of luck.

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

are you getting a rotten egg smell? try disconnecting the exhaust and see if it stays running. if it does replace the cat. convertor

I put a new fuel pump, fuel filter, and a fuel pump relay and the fuel pump is still not coming on. I am not getting any fuel. Can you please tell me what it might be.

Turn the ignition key to the run position and pump the accelerator 3 times within 5 seconds.
