Last weekend while I was driving all of my gauges started bouncing left and right, then it stopped and they settled down like the truck wasn’t running. I stopped at a gas station and made sure the battery terminals were tight and when I started the truck back up everything was working fine.

Today I went out to the truck and when I tried to start it I got nothing except the tach and speedo needle moved up maybe a quarter inch and stayed there. I rechecked the battery terminals, looked at the grounds under the hood and under the truck and they look ok, and I checked every fuse and didn’t find any blown. When I tried to start the truck again it started up and then died after a few seconds. Now every third or fourth time I turn the key it’ll start up and run for a few seconds and then stall. Any help would be greatly appreciated.

I took the cover off the steering column and made sure all the plugs in there were fully seated and it seems to be working again, but I guess we’ll see if it starts again.

How old is your battery?

Who do you know with a Tech-2 or other bi-directional scan tool? Need to pull the BCM codes and check condition of the battery as the truck sees it.

Ok it worked fine all day yesterday, today it started fine and then the gauge cluster died again. I parked it and when I tried to start it in the parking lot it was doing the same thing it did yesterday, nothing for a while then it would start and die after a few seconds.

Check those connectors for corrosion, but it may be the ignition switch.... Gave up looking because I thought you fixed it. Lol

How would I be able to tell if it’s the ignition switch?
Looking for a schematic to have you check the run side of the switch, or something that is energized while in run position under the hood. Like a relay or something..(non acc position) so the diagnostics will be easy. Kinda busy with my 5 year old right now though lol.
