Nuetral safety switch is easy to get to. Pull the side panel off the console on the passenger side, unplug it, put a wire with some alligator clips on the ends to jump it. When you get just nothing from the key on but the gauges and stuff come to life then I would think that it'd be neutral safety switch. If your gauges are all dead start checking the battery.

well.. here's what I checked.

starter connections are all good and tight.

went to the battery connections, they're all tight.

tried starting the car again, volt meter read 0

so it leads me to believe its the battery. I'll throw it on the slow charge

If you have a multi meter check the voltage at the battery. The nwork your way down the line. If your volt meter reads zero it does sound like the battery but it went pretty quick from the garage to the driveway.

At least 3 maybe 4 times I had problems starting and thought it was the starter, alt, or other, and every time it was the battery (Or connections to the battery). You'd think I would learn, right?

I would bet that the fuseable link took a crap. The flex coating might be intact, but the link blown within.

Worst case you can jump the posts on the starter, and check for crank that way.

In the meantme just run a jumper across the two purple ones to see if it is the problem. If you want to check and see if you are getting 12 volts at the starter when you hit the key. You will need two people for this. Check the purple wire when you hit the key. This is the one tha tgives juice to the selonoid. If no juice probably the NSS

Take the connections loose at the battery and reinstall. Every time I've had or heard of a sudden no-crank, it's been the connections at the battery. Sometimes they seem tight and aren't sometime they look clean and they aren't. I'd bet my hat on connections.

Jump it! That switch also controls the backup lights. That is what the other 2 wires are for. I would not figure any one local would have it.

i just checked everything out with my dad, the nss does have power

same with the battery..

and one side of the solenoid (outside, orange wire) reads 15v

the inside reads ZERO. so...
I'm not sure if both wires should be giving juice, or if only one should

On the solenoid the three terminals are
1 the large terminal with power from the battery
2 The small terminal 'R' with the power from the ignition switch (key in start position)
3 The small terminal 'S' with the yellow wire that goes to the coil, bypasses the resistor wire when starting

The yellow wire R should have 12 volts with the key in the ON position the purple wire S should have zero. With the key in the start they both should have 12 volts.

On the NSS you should have 12 volts in and 12 volts out when you are in park or neutral. In other gears you will have 12 in but nothing out.

If the yellow wire has 12 volts in the ON position then the resistor wire to the coil would be always bypassed. The yellow wire should only have 12 volts during starting.
I had the 'R' & 'S' backwards in the above post now corrected
