What is a GEM? I did park it overnight on Sunday but I started it Monday morning without issue to put it back in the carport. After sitting in the carport over night...the next day is when I had the no start issue. No I don't have anything wired into that circuit.I thought I heard that the 4x4 module was up infront of the glovebox - I know there is something up there, but never really looked at it too hard.
Not sure about the security.
But the GEM might be suspect. If you have had rain, then that is sometimes where the water goes and causes some weird issues. Do you have anything else wired into your true aftermarket?
