Ok, figured I would get some other opinions on this.
1997 Chevy pickup 5.7 Vortec 350 no start..
I could not hear the fuel pump when I turned the key. I checked the fuse and it was good. Can hear the fuel pump relay click when turning the key. Everything points to a bad fuel pump which is common in these trucks. I then tilted the bed and got underneath to the top of the fuel tank and put a test light on the harness coming from the front to the pump. I had power to the pump but the pump was not running so I pulled the pump out of the tank and installed a new one.
So, new fuel pump in the tank and it does not work. I have no fuel pressure, cant hear the pump run when I first turn the key and I again tested the power coming to the pump and my test light lights up when I turn the key on at the fuel pump. I wire brushed the bolt that holds the ground wire on the frame, and wire brushed the frame where that connects.
It again seems like my pump is bad but its brand new. What am I missing? I have power to the pump but it is not working.
I attached a picture to show the wires. The middle wire that is going to the pump is the one I get power from when I turn the key on.
I’m
stumped

Success!!
Just took a couple times to get pressure back and air out of lines as I put new filter in also.
New fuel pump was not working out of box (even when I jumped it)
The next new pump worked when I jumped it but would not run due to the new relay that I put in. When back to my old relay and she runs like a champ!!
