engine not cranking over?

I was waiting for my wife to come out of the store and parked in the shade on a pretty steep incline facing downhill and accidentally fell asleep when she came out and woke me, I panicked and immediately shut the car off. Well, it would not start back and was starting to overheat so from where I tried to start it back, it just went further and further down this incline until I was stuck. Couldn't go anywhere. So, when I tried starting it again. It was only cranking would fire up . I checked the Shrader valve on the fuel rail and nothing was coming out. But I could hear my pump running. So I thought maybe it didn't have enough fuel. Went and got fuel ,I thought maybe it was the ignition switch, but I replaced it and didn't fix it. put it in, and now it's not even cranking. I tried to just bypass the starter solenoid just to get it home and I could get it to crank that way but will not start up. Oh, and the fuel is gushing out at the rails now so that problem is fixed. Why won't it start up ? I've been stuck here for 5 days now. Maybe the neutral safety switch? I just don't have any experience with those. Please help.

Okay, correction, the red wire going into the ignition switch has 13v.
The yellow only has 5 but the red w white stripe has 13v.
Now I'm going to check the green at the NSS.

Are you still with me Ken? I ran a separate wire strait from the battery to the dark green wire at the NSS connector and all sorts of things come of. All the gauges started working properly, the security light went off and u could feel the gear shifter sort of tighten up. But still no crank and no PRNDL indicator.
