SOURCE: 1999 chevy silverado won't start.

You need to test the fuel pressure with a special gauge, the pressure should be greater then 35PSI. The Vortec set up has more to it but what you seem to be discribing is a faulty fuel pump. Im assuming that the fuel filter was changed too. But you need to have a special tool that will allow you to isolate the fuel flow from the tank to the engine. popular reasons for fuel system failiers are filter, pump, fuel pressure reg. valve(located underneath the plenum) and not common but maybe fuel pump relay.

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.

After you dump the fuel in the throttle body it will continue to run on its own or die as soon as it burns up all the fuel you dump in? Do you have access to (Noid lights)? Are both plugs attached to the distributor?

The last pieces in the chain are the fuel regulator and the injectors. The regulator is inside the throttle body, but it sounds that maybe the injectors are not firing. For nothing else, check out the connections to the injectors. Possibly they are clogged. Try a few treatments of injector cleaner.

85 chevy 2500 5.7L fuel gauge stopped working and truck died. Fuel pump was replaced 3 months ago


Make sure battery has a full charge and battery connections all good. Have a helper crank it while you visually check for spark at the spark plugs. Does distributor turn when you crank it? If spark everywhere, check fuel. If you have a carb, mechanical fuel pump, sometimes you can take fuel supply line loose from carb, aim into container, bump the engine, see if gas comes out, if no gas have to back track. If there is gas, take the air horn off carb, depending on the carb, you may be able to remove air horn w/o removing carb, see if any gas in float bowl, if no gas, maybe you need a carb kit?
Any vehicle needs fuel--spark--compression, right amount at the right time.

Changed fuel filter in 2001 Chevy SIlverado 4.3L v6, pump is working but no fuel to throttle body. Will start and run if sprayed with Carb cleaner, but stop after spray stops.


It is possible for pump to run but not put out pressure. Sounds like you need a pump. There is a valve on the fuel rail where you can test fuel pressure. Its just like a tire valve. Just push in on the center pin to see if you get a spray of fuel. It requires around 55 pounds to run. You will need to connect a gauge to the valve to check for proper pressure.

I just put a fuel pump in my 2000 chevy silverado 2 weeks ago and now it wont run and all the fuel pump will do is click when you turn the key on but it only clicks once?


spray gasoline or carb cleaner into intake. If engine starts, it's a fuel problem. You have a bad (new) fuel pump or relay. Either no power to pump or pump is bad (unlikely but possible).

Process to change fuel pump on 2001 chevy silverado 1500


take the six bed bolt loose and then take three buddies slide the bed back put in the new pump slide it back n place and put the bed bolts back in. if u drop the tank u can easily break the hard plastis lines that go to the fuel tank. u only have to take the fill lines and taillight wires loose this way its alot quicker, and easier.

NEED DIAGRAM OF 2003 CHEVY SILVERADO TRUCK EXT CAB, 4.3 LITRE V6 ENGINE. SO WE CAN CHANGE OUT FUEL PUMP


fuel pump is on the engine or either in the gastank follow the fuel line chevys are the easiest auto to work on a new i think yours is in your tank remove both straps and remove hose to filler neck. the fuel **** is in the center of th tank removed by a lock washer system holding the pump in also be careful that you follow the fuel lines though and that you remove bolts that hold the fuel ine to the frame and up to the engine or fuel filter then engine an up to the carb that way you can lower tank without bending fuel line any way however you took it off put it back if a human put this thing together then a human can fix it
