2003 Tahoe z71 5.3 flex fuel pump issue
Hi all,
Wednesday night we had a cold front freezing weather. Thursday morning I went to start my Tahoe and it wouldn't crank. I replaced the fuel pump and filter but still no start. I have checked the fuel pump relay "good" I also tested the fuse "good" as well. Checked power to the pump "good" and grounds "good". But the fuel pump will not come on. I have replaced connection harness to the pump even went and bought another pump to see if that made a difference. Still not coming on. I currently have the truck on a lift with the fuel pump out trying to make it come on before reinstalling the pump!! Help , any ideas or suggestions thanks
