Haha! Okay.... an automatic ranking system. I'm honestly not familiar with those. No biggie. I was just curious.
I found the schematic. I just didn't figure it would be under chassis electricals. I would've thought engine electricals.
Anyway, from what I gather there are two fused inline of each other on the pink wire circuit; one 10amp and one 20amp. No relays. It'd be nice and simple if it were just a problem with one of those fuses. So, I'll just need to locate them on the vehicle to test/inspect. My experience with fuses, though, is that when they burn out they just go altogether and nothing happens. IOW'*, I would think if a fuse went out, I wouldn't even get an intermittent function. Just one minute it works and the next it doesn't....ever. Until you replace the fuse that is.
Thank you, gentlemen. I'll post my results later tonight.

if it blows the fuse then something on the circuit is shorted. if the fuse is not blown but no longer supplies the power to the circuit could be loose socket or corroded connections
"Oh, what'* this switch do?". Um....it'* an alarm. It' cuts off the ignition!
Man, I feel like a complete idiot. I kinda forgot that alarm was there. When my wife was given the vehicle to her by her dad, he told us it was there. But, he didn't tell us it cut off the ignition. Well, I thought I'd disabled it because the horn didn't go off anymore. I don't know anything about alarm systems, so I never suspected it did this. Well, I saw the switch was on when I was under the dash trying to get to the fuses and it got me to thinking. So, I tested the pink wire with the switch on and also off. With it off, .5v'*. With it on, of course, 12v'*. Man....I want to scream....lol!
Verdict'* not 100% out, though. I'll call it fixed when the battery'* been recharged and it actually fires up.

This is the same reason why I persist that people have their alarm/remote starter systems installed by a competent shop or dealer. Too many things can go wrong down the road and end up interfering with diagnostics.
Many thanks for the support, guys. The car is indeed running. I'm laughing about it now! I must have kicked the switch with my foot climbing in the car that fateful morning trying to get to work and it wouldn't start. For now I will leave it realizing it is there and what it does. Ultimately, I need to pull it out of the circuit, though. It'* a simple toggle switch design, but I don't know what wires go to what and don't want to fry something by nutting wires together even though they appear to match.
So, yeah....short visit here at the gmforum, but it'* a car. I'll probably back! Ha! Later, gents!

glad you got her figured out.
mike- the "pro" installers are the ones who haphazardly install crap with those junk crimp on connectors, just throw crap together, etc. they are a bunch of kids who could care less if you get stranded on the side of the road
