Usually you can hear the pump running. If you can not hear it run for a few seconds when you first turn the key to the run position, check the fuse/relay/wiring first.

Check your TPS Sensor. My 1995 Chevy Astro Van did the same thing and I thought it was the fuel pump but I was wrong.

yes you have to drop the tank. you will also need a fuel line tool to unhook the fuel lines. before you drop the tank see if tou can reach and wiggle the electrical connection on the top of the tank. these pumps have a pigtail issue. please rate

Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

SOURCE: my 2002 chevy silverado struggles when idling

I had the same truck and it had lean codes.
The intake gaskets go bad causing too much air to enter the chambers. ITs the same gasket for the 4.8 and 5.3 litre motors.

upon tear down i found the fuel pressure regulator had fuel in it indicating the diaphram went bad.

Fixed and everythings all right.

BUT check your codes first I don't want to you to do a tear down with out knowing what the computer is doing first. Auto zone does free diagnostics and tell you what the codes are. Let me know I can guide you from there.

SOURCE: I have a 2002 chevy blazer 4.3L that wont start

are you using the original key ?? sounds wear but in the key switch there is a sensor that detects if the right key is in use otherwise it will kill the power to the fuel pump or it can be a fuse look under the left rear passanger seat there is another set of fuses and the other set of fuses are on the driver side near the door and there is another set of fuses and relays inside the hook next to the battery

SOURCE: 2000 Chevy Astro Van while driving just stops running

Hey I had my rotor and all that stuff replaced on my 2000 astro van, Intermittently it would not run, The problem was I hit a puddle one day and water flew up on top of the roter like 3 drops, it created a trace( it was arching) Thats why it was intermittent.Take a look at the cap look for like a discoloration on it clean it and put it back on.Sounds too easy but remember I had all new parts too.

99 chevy astro van fuel pump what other vehicle Parts Interchange


You don't want a used fuel pump. GM fuel pumps are just not dependable. You can order one from eBay or amazon for less than a used one will run you.

1992 Chevy Astro won't run, will start up great with starting fluid, or let it sit overnight.


You need to check the fuel pump pressure and I would change the fuel filter in the process. Sounds like you may have a bad fuel pump.

The fuel pump might be working but it is not priming. When you turn on the vehicle, the pump sends fuel under pressure to the injectors, to "prime" or have fuel present to be able to start engine. Without it there will no fuel available to start it. You are manually priming the engine, and the fuel pump is taking over from there. Check connections to fuel pump and replace if necessary. It is not an inexpensive repair

I have a 1990 Chevy Astro van that stopped running on me while I was driving it. I towed it home. I replaced the fuel pump and it ran for a little while and started running very rough. So I bought another...


You say you replaced the fuel pump, what about the filter? If the filter is clogged it can cause this as can ignition. Since the car started for you after the fuel pump was changed the original problem was the fuel pump. But you should never change the pump without installing a new filter.
