The connector with the gray wire and the black wire is for the pump-gray wire is power wire, black wire is ground. Check the gray wire for power, when the engine is cranking. If the gray wire has power then, and no pump, check the black wire for a good ground. If ground is good, the pump has to come back out for inspection- it is not turning on as it should.
If no power on the gray wire when engine is cranking, check fuse #22-a blue 15amp fuse for the fuel pump circuit. If fuse is good, you will need the wiring checked for the fuel pump relay, because it is not turning the pump on as it should. The computer sends a signal to the relay to turn it on and send power to the pump.

Can see what the actual temp. of the engine is . GM had bad stepper motors inside the instrument cluster's 2003 to 2006 , these stepper motors control the gauge needles . Testing what the real temp is an not going by temp gauge . harbor freight tools sells a tool under $30 bucks that can check engine temp .
Infrared Laser Thermometer .. Point it at the thermostat housing . Can use it to tell what temp. the thermostat open .
But , testing is the key ! Not guessing .
