Could be the fuel filter that is clogged or the injector rails that are clogged to!!

See if you have fuel pressure at the injector rails.

If yes that clean all of the injectors and injector rails .

Check for spark to the spark plugs, while cranking the engine. If no spark, you could have a bad ignition module, or a bad crankshaft position sensor. The crank sensor sends a signal to the computer, to start the fuel pump and signals the ignition module to start firing the spark plugs. It also drives the tachometer through the computer (PCM) Powertrain control module. The ignition module can be removed and taken to a parts store to have it tested. The crank position sensor is not as easy to test. Easier to just replace it. Good Luck. But wait, I have seen people replace the fuel pump, checked the fuel pump harness for power, and all was good. However, if the fuel pump does not have a GROUND, it will still not operate. Might want to check that. Have fun.

SOURCE: I cant get the drop the fuel tank on my 2002 chev avalanche

There are to straps and the filler hose and the vent hose and a wiring harness. You may have to lower the rear first. Also that model may have the EVAP canister mounted to the tank.

SOURCE: Fuel pump issue, 2004 chevy avalanche

1s the fuel pump should not be that noisy, and the problem u are describing is a defective/worn out fuel pump, it is taking time to built pressure, replace the fuel pump and don't forget to replace the in line fuel filter as well.

SOURCE: 2002 Chevy Avalanche. Truck will not

Do a bench test on the starter. Remove starter, hook up a ground cable to starter, and positive to two prongs on starter and it should spin. You can do this in vechile too but not suggested due to risk of injury. If it doesn't spin, probally a solenoid or the starter it self. Unlikely but possible.

SOURCE: How do you change a fuel pump in a 2003 chevy

drop the fuel tank. (hopefully it is just about empty) on top of tank unplug power plug disconnect fuel lines and remove locking ring on top of pump unit, lift pump up out of tank. replace in opposite order. It really is that easy if the tank is empty as you can do it all with no jack . I did my yukon xl in about a hour but i had a friend handing me whatever i yelled for. I also removed the rear driveshaft so i would have plenty of room to sit up under the truck and god was that nice. Make sure you support the rear axle up with jackstands, yes jack rear of truck off the ground.

Ran out of gas, car wouldn't crank replaced fuel pump, fuel relay, and in line fuel filter and still won't crank on 2002 chevy avalanche


still won't crank ? how's your battery ? starter ? starter solonoid ? if your engine does'nt crank , its dead ! would'nt you check the battery first ? then move on with checking the starter circuit ? seems like your putting the cart before the horse ! first of all, when you run out of gas, you need to replace the FUEL FILTER, your engine just sucked the dirt, garbage, etc., out of the tank. there's plenty of sediment in the tank, don't know how it gets there, but, you'd be surprized ! talking threw experience !!! I operate heavy equipment, its a cardinal sin to run out of fuel !!! you say you replaced the inline filter, which one, up by the engine or the main filter, under vehicle along frame ? are we talking about the same animal, PLEASE CLARIFY !

2002 chevy avalanche died at a stop light and now wont start back up. it just cranks.


Those are known for having the fuel pump go out. Take the gas cap off, open the little steel door with a screwdriver and have someone turn the key forward, not cranking it over, just turn it until all the dash lights come on and see if you can hear the fuel pump kick on for about 2 seconds. You definitely need 2 people to do this. If you can hear the fuel pump then its probally not getting spark.
