My 2004 Yukon XL keeps shutting shutting ​ off while driving I'll let it sit for a minute or two or tap on the gas tank and it starts back up it only does this in the heat of the day at night when it's cool it doesn't do this is it my fuel pump going bad

You need a new sending unit

Hey guys. I have a 2004 gmc yukon xl "t" series i already replaced. Spark plugs, cables, ignition coils,o2 sensors, evap valves and intake gaskets but still the random misfire still there now i was going to replace the fuel filter but i can't find it oh and the knocking sensors with a motor flush. I saw a video where it says that only the z series (flexfuel) truck has it so what do i need to do now? Oh and on the code reader it says: take to a technician to verify fix.
