Thanks.

check for voltage at the pump. If it has 12v there, (and a good ground) then pump is bad. there may be a pump fuse on the fuse block (can't remember) but if you find it has blown, the pump may be getting ready to fail. If fuse fixes the problem, replace it and carry an extra with you, then change the pump.

Your ECU is what acctivates your fuel pump realy. Put the key on the run possition and pull the ecu fuse for a few seconds and reinstall it ans it should accivate your realy for 5 seconds, Good luck.

Sounds like the Vehicle is POSESTED LoL ,
I would Hardwire a Key on wire around the origanal wires. Fuel Pump IS NOT going to set a Trouble Code at all ever, as it is an electrical component like headlights, as for the missfiring & guage reading above full I see nothing in commen with the 2 as long as the Supply and return hoses are
not swaped witch they cant be because it wouldnt run (thinking on keyboard) LoL-- Also check Fuel presure regulator. Hope this Helps you.
SOURCE: we have 03 avalanche,no power to fuel pump,checked
there is a wire harness above the tank and are known to go bad they give you a new one when you buy a pump from napa maybe its corroded
