Need step by step to determine if fuel pump bad

[trailblazr81]

Is there a write up, prefer with pics, of the step by step process of determining if its my fuel pump thats not working. I get it to crank but wont start. I know to check fuse, fuel at schrader valve. Then how do I check the IFS in the trunk? Which wires am I checking at the IFS, and CCRM?

Have you tried starter fluid? Listen for the pump to prime in the back of the car.

I dont hear the pump, and theres nothing coming out of schrader valve on fuel rail.

to best determine if the pump is turning on would be to have a friend stand with his/her ear at the fuel cap while u turn the car to ACC...u should here the pump kick on. If not, its definitely the pump.

If this makes sense, on the Fuel Pump Driver Module I only see power on #7 light blue/orange and #10 Brown/Pink.
