Vehicle suddenly quit running while driving
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.

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.

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

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.
