How many miles are on the truck? If it is high mileage, then you most likely are looking at a fuel pump change. The pump is in the tank, and dropping the fuel tank can be a daunting task for the uninitiated DIY'er. Take heart though, because it is not an impossible job. Depending on the engine code (look at the air cleaner: round and on top of throttle body=Z code, rectangular and in front of engine on top of radiator=W code) the hose connections between the fuel pump module and the truck plumbing are different in that the Z has simple fuel hose jumpers (relatively low pressure) and the W has plumbing connectors more suitable for high pressure, and thus require special tools to disconnect ( look in the tool section of your local auto parts store for a set of the different sizes) Raise the truck at least 8 to 10" off the ground. Jack stands under the frame at all four points, or you can use 4 concrete blocks, one under each wheel. Insure that both the transmission is in Park, and the Emergency Brake is set. DISCONNECT THE BATTERY. Remove as much fuel from the tank as possible. Remove the stone guard (plastic covering), from around the tank. disconnect the fuel filler assembly/plumbing.
Loosen the tank strap bolts on the outboard side of the truck. At this point either have help, or a floor jack to take the weight of the tank/remaining fuel. Disconnect the fuel pump electrical connector, and when the tank is lowered enough the pressure, return, and vapor fuel lines which are just above the middle of the tank. Remove the tank from under the truck. R & R the fuel pump and filter sock, or the entire module as necessary. Reverse the above steps and drive away! . While you are at the auto store, look into spending $20 for a Hayes manual for your truck. It is usually a wise investment to have some technical assistance on the job site. Hope this helps. Bob

No check engine light fuel pump dont work

That is a very involved answer. First I would disconnect the fuel pump and apply 12v directly to the wires to the fuel pump to rule out whether or not it is toasted. If it runs when you supply power to it, you'll need to isolate which wires are grounding to blow the fuse. Think about recent work done on the van as this may give you a clue where to start. Good Luck!

My 95 Astro Van won't start, i think the fuel pump is the problem, since i don't hear a humming sound. Is there anything that could be causing the pump not to operate besides it the pump being no good?...

this is what happens, somtimes you dont get a warning, and sometimes you do,hears a trick, have someone try to start the van while you beat on the bottom of feul tank see if it starts if so then replace the pump, many times the bad pump will start if itsw jared around enough to make contact, hope this is helpful.

1993 Chevy Astro Mini Van not starting

if your mini van has a 4.3 litre engine v6, when you turn the key on you should be able to hear the electric fuel pump start. the fuel pump is inside the gas tank,if you hear the pump you might want to change the fuel filter. The thing about computerized engines and a throttlebody is that you need a fully charged battery to start work with.
