I have a 2002 GMC Yukon that will not start if the gas is below 1/4 tank. I add some gas, go to a station and fill it up. I can fill it with 20 gallons, it holds 26 gallons so I assume the gauge is correct. What’s going on? ---

As a guess I would say there is a problem with the inlet to the pump. Perhaps the inlet is sticking up somehow so that the last 1/4 tank of fuel is below that level. The only solution to this problem that I see is to remove the pump and possibly the tank to check things out. ---

Or the pump is getting weak. ---

You mention adding gas before going to the station. How much gas are you adding?
