This morning I started the truck and started jotting down time, odometer reading, etc for my work travel log. While I was doing that the truck suddenly just shut down as if I had turned off the ignition. I turned the key to off, then back to on and noticed that the fuel gauge was on E and the check gauges light came on, although I know I had a half tank in there. Also noticed the SES light didn't come on. Tried turning to start and had nothing. OK fine, since the cluster is acting wonky I guess my original ignition switch finally died after 10+ years. Thankfully I hadn't put away my summer car quite yet and it wasn't snowing.
On my way back this evening I dropped into Autozone and bought a new ignition switch. I just installed it and it does the exact same thing. Figures. I start digging more and found that fuse #10, labeled PCM B (20A) is blown. Fuse #28 is PCM 1 and it is OK. If a PCM fuse is blown that can't be a good thing... Swapped it with a new one, turned the ignition, and the SES light came on for the test as it should. Tried to start, nothing. Released the key, no SES. Checked the fuse, blown. Also I smelled an burnt electronic smell. Awesome.
It is dark and I can't really see much so I'll have to come back to this in the daylight, but does anyone have any ideas what I should be looking for? I looked at the PCM itself and the wiring and it all looks OK.
For what it is worth, I started having a slow coolant leak from somewhere, but I have no idea where. It is just dripping off the bellhousing underneath but I don't know the exact source. Maybe it leaked onto something important...
I hit 166k miles with this truck and all of a sudden it goes full retard on me and starts giving me fits
