Question about Chevrolet Avalanche
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.

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.

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.

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.

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.

i replaced the fuel pump on my chevy avalanche last year there is really only one way to replace it ,you have to take the braces down that holds the fuel tank up, unhook fuel lines, and rubber filler hoses, drop the gas tank to be able to get to the fuel pump. i bought a book at auto parts store that takes you step by step on how to do it.
