Thanks for the diagram and pic Jake. I was checking the right wire.G-spec, the crank pulley is fine...thought of that along with the timing belt, but it turns over fine.While waiting for the tow truck I tried the wire on the stop solenoid again and when I tried cranking it over, I noticed the glow plug light didn't come on. Turned the key off and back on again and no light. I waited and did not hear any glow plug relay click. I remember reading somewhere that the two are connected, but not sure how.
The bushbutton switch is a heavy duty switch that was used as a starter switch on my S10 (ran wire direct from the positive at the starter to the switch and back to the solenoid on the starter and there's a lot of juice in that circuit so I'm hoping it will work).
