2002 Chevrolet Avalanche no fuel and no power to the fuel pump.

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

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

sounds like the check valve in the pump is letting the fuel drain back try just cycling key a few times before starting this will prime pump and lines. if cranks up this is most likely cause a fuel pressure gauge will confirm

Did you get new clips with the new fuel pump and directions,,,,,,,if not goto a chevy dealship at parts counter and they will tell ya

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.

check the crank positioning senor,that runs for about $50.00
hope that helps

the fuel pump relay is located in the underhood fuse box. but it is not required to replace if it is defective then was probably the problem all along

if no codes check fuses and connections 4 fuel pump , possible fuel pump going, turn on and listen for hum from tank if comes on than check fuel pressure if low or none fuel pump defective

fuel pump relay on the engine side fire wall passenger side. replace that and check fuses. I had the same issue and this fixed it. the ground for the pump is also located on the frame rail by the gas tank. make shure it didnt come loose

Gm has a real problem with fuel tank sending units. That is what is wrong. You need a fuel tank sending unit. You can only get them aftermarket with the whole fuel pump module, but you can buy them seperate if you buy it from the dealer.
