Your fuel level sending unit is bad. Replace your fuel pump.

SOURCE: 2004 Yukon XL Denali fuel gauge fluctuations

Your sending unit for the guage is part of your fuel pump in the tank. But first try your fuel pump relay, may be working intermittenly when you hit a bump or something. Or possibly a loose wire somewhere along the way. Much less expensive (worth a look).

How do you check the fuel pressure


First disconnect the fuel relay and start the engine and let it run until it cuts off.There is a fuel service port that is on the fuel rail.You will need a fuel pressure gauge then connect it to the service port and turn key on and read gauge.After reading gauge you can put the relay back in.

My GMC yukon XL 2001 engine runs after 4 times of cranking.


Try turning key to on only, not start, 2 or 3 times first then try to start. If it starts good first try, then I'd change my fuel filter & then have fuel pressure tested if fuel filter didn't help. You may be looking at a new pump, but lets do filter & test fuel pressure first.
