have you checked the fuse ?

Check fuel pump relay under hood and fuse.If they are good it is going to be the fuel pump.

While more of a comment than a solution, have you checked the computer for codes? If there is a issue with the ECM (Electronic Control Module) the On Board Diagnostic system should tell you exactly what the problem is. It almost sounds like you have a clogged air filter and it is choking the engine down. However, if it is not a clogged filter, you could have a defective O2 Sensor. The Avalanche has 4 sensors. One before and after the converter on each side. These sensors tell the computer how to adjust the air/fuel ratio. Good Luck!

probaly a broken rear/lower planetary set or ring gear is broke

Has the power supply been checked as constant and spike free?Have you opened up the pump to determine exactly why it failed as that would give you an area to explore.Also make sure the pressure relief valve is working at the fuel rail correctly.check that fuel return line is free and clear

door handle broke depends on what door handle it is.if door cant be open on out side out side door handle broke.if cant open door on inside inside door handle broke.door handle clip that connects to latch rod broken.when you try open door handle not engage to latch rod.door not going open.have to replace door handle with new clip holds latch rod in place.

anytime you change the filter in a diesel you have to bleed the air out of the fuel system. The pump won't auto bleed the fuel system for you. every place in the fuel system that has a flare type connection needs to be bleed, start at the connection closest to the tank, loosen the connection and then crank the engine until you see diesel fuel drips from that connection. Tighten the connection while the engine is still cranking. Move to the next connection that is going toward the engine. Continue on in that manner toward the engine until you reach the injector pump/injector. Once you reach the injector pump be VERY aware that the fuel is at VERY high pressure. Do NOT put your body parts in the stream of high pressure diesel fuel. It could kill or injure you! Once you bleed all the way to the injector pump/ injector, the truck SHOULD start. Do not bleed after the injector pump because of the pressure involved, it is WAY too dangerous.Good luck!

Crank position sensor if its an 8.1 liter 2500. Do the research. Big problem for them...I had it on mine bad. ... Good luck frank

any codes? check fuel pressure.

dealer only ,expensive repair

If a repair shop did the work, take it back,the job wasn't done correctly

Could be fuel filter, idle air control valve, or idle control sensor, or a vacuum leak.
