Mystery Wiring Issue on my 2008 gmc canyon

went to start it, all electric power on ( radio, dash etc) but no start, no solenoid click, nothing.. Lifted hood, after a few look arounds, noticed left signal light assembly mounting prong was out of its socket. pushed it in and all was normal again.? There are no wires involved with that mounting thing. Must have something to do with start interlock system? Any ideas? Weird.

Welcome to the forums.

Usually the anti theft on GM's affects the gas flow so it will crank but not start.
Not sure on your vehicle. Make sure it's not in anti theft mode.

Instead of starting in park.... try neutral.

So that means the clutch needs to be down for the engine to be started. Check the clutch switch.

Clutch switch is ok, so what else can it be, tied to that signal light assembly?

I wouldn't think a disconnected signal light connector would prevent engine starting but you can't argue against success. You need to get a factory wiring diagram (not a schematic) for your vehicle to see how a disconnected signal light connector affects power distribution, especially to the start circuit.
