Do you have to drop your tank to change fuel pump on 2002 gmc yukon xl

Fuel pressure may drop due to a leaking injector or bad check valve in the fuel pump itself. The regulator does not come into effect until the engine is running and a vacuum supply is produced to it. If the regulator is leaking internally, it could send fuel back to the tank as well. Prime the fuel line and pinch off the return line ( if possible ) to eliminate a regulator problem. If the fuel pressure drops with the return line pinched off, suspect a leaking injector or fuel pump. If injector is leaking, the vehicle should run rich and cause a hard start/rough run condition

You have to drop the gas tank if that is your question.

have you checked to see if engine is firing? ignition module can go bad and you would loose fire and fuel at the same time. i replaced one on a chevy truck last week and it was located beside the ignition coil.

you have to remove the fuel tank and remove fuel pump module assembly.first before you can replace fuel level sending unit.

yes, No way out of it

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

change your fuel filter when you get low on gas if there is trash in the tank it will wind up in your filter i would start there

sounds like the fuel pump you should change the fuel filter
