Hey guys, I need help ASAP. When cleaning my truck yesterday, I degreased underhood and the full undercarriage. I hadn't driven it in almost a week, so I went to start it and it stalled. It runs for a few seconds, 1-2, then stalls. Here's whats weird, sometimes the key sticks and doesnt fall all the way back to the 'on' position. Well, when I restarted it, it indeed stuck between cranking and 'on' and would run just fine. None of the accessories worked obviously, but it would run and even rev. As soon as I kicked the key back to the 'on' position so it would be driveable (truck will stall if you try to put it in gear when its in this in-between position) and boom, stalled again.

Checked fuel pressure, its consistent at 45psi pre/during/post starting and after stalling.

I need the truck up ASAP as I use it for towing around my kids during the weekends. Could it be a fuse? TPS? MAF? Someone said the key cylinder might be bad but wouldnt that make my radio and climate control fail also? Because that all stays on.

Thanks for all help/suggestions

Ill also add, there is no bog, misfire, studder, or anything. 1-2 second idle, then boom, complete shutdown motor wise. No check engine light either

Sounds like you need a new ignition switch either way, so I'd start there
