04 GMC Yukon won't start on less than 1/4 tank of gas

It is not necessarily the flow of gas that is important. You need at least 40 pounds of pressure for the injectors to operate correctly.

I HAVE THIS EXACT PROBLEM. If you got this repaired, what was the fix??

the fuel pump is cooled by gas so if u run it low alot or {OUT} it can burn it up
keep that tank at 1/4 or u will pay!!!

it sounds like the fuel pump might have died, or blew fuse or relay see if it gets fuel at the motor

hi, the banging on the tank is a typical fuel pump scenario , but to last for years is not very likely , i think it needs to be diagnosed to see what's missing when it wont start .

sending unit for gas gauge is not correct

I had the same problem. I had a few different mechanics tell me that the fuel pump is starting to go out when it does that. The fuel pump is located in the fuel tank, and the gasoline keeps the pump cool and lubricated. When the fuel tank is less than a 1/4 full, the pump is not submerged anymore, and can have trouble sending gas to the engine. My emergency fix was to get underneath the car on the driver's side and bang on the gas tank about three times. It will start up, and will run great unless you turn your engine off. But eventually you're going to need a new fuel pump. Once I replaced it, the problem went away.

check fuel filter could be blocked,if it s ok check fuel pressure if its low ,fuel pump

i would try to get it jump started first it should give it enough power to turn over
