Q: No spark, no fuel pump until I jump the starter switch.

asked by on

Hello. I have a 2000 Chevy Silverado 4x4 2500, with the 6.0. Here a couple of months ago it started and died, then when I went to re-start it wouldn't start and I didn't hear the fuel pump so I assumed it went bad and replaced but truck still would not start. I then checked for spark and found no spark. I checked fuses, replaced relay and finally gave up and took it to a Chevy mechanic to just diagnose problem and I would fix. He called and said truck was running when jumped at ignition starter switch, that it needed a new one. So I went and got a new switch, installed it and the same thing still happens, thought maybe I got bad switch but after trying a different one I now know for sure it wasn't the switch. I can jump from the Red/White wire in my ignition starter switch, to the Red wire in switch and it runs fine until I remove jumper. Could this be the key cylinder or cylinder housing? My truck is the Work Truck so nothing power and no anti theft that I know of. Thank you
