not sure what the stereo has to do with it...but maybe your temp wire grounded (somewhere other than the sending unit)and blew a fuse or fuses? the light should come on when it gets a ground..

unless...did you install a stereo and security recently?, did the security have a start disable? did those 2 wires get put back together. search online for a wiring schematic, and follow it.. it is pretty easy to follow. get a voltmeter and start tracing...even if starter tested good...was the main large cableconnected? what about the small ign. wire on the starter solenoid stud? is it hot (12v) when key is turned?.., follow it back through the firewall to the fusebox, hot on both side of ign. fuse, then follow to the switch on the steering column, or through the neutral safety switch, on te shifter.. see? easy....just follow it.

1st check and make sure your fuses are good

I'd start by touching a screwdriver to the lg lug on the starter to the "I" terminal on the starter, basically bypassing the key. If it turns over, you have a disrupt of the wire connected to the "I" terminal (wire should be purple).

To test the purple wire, use a volt meter and see if you are getting 12v on the "I" terminal when the key is turned to start. If you get 12v, you have a bad solenoid.

If you don't get 12v, check your Neutral Safety Switch (NSS) depending on your setup...... Automatic column shift= lower end of the steering column..... Automatic floor shift =bolted to the shifter/under the console......... Standard shift = located somewhere on the upper end of the clutch pedal........ unplug the two wires from the NSS and jumper them and see if it starts. if it does, you have a bad NSS

If it doesn't check the ing side of the NSS for 12v when the key is turned to start, if no 12v...... trace that wire to the ing switch (ing switch should be located on the lower end of the steering column)

Mark the location of the switch as it sits on the column, remove the ing switch (it's not the key part) the switch should have a bunch of wires connected to it and two bolts holding it to the column. As you remove it there will be a sm dia rod leading up the the key portion and sitting in the slotted portion of the switch. Place a small screwdriver in the slot and it should cycle thru the Accy, Run and Start. If it cranks using the screwdriver………. You need to adjust the switch when you bolt it back to the column, there should be slots to allow you to slide it up or down as you bolt it back on.

If it doesn’t crank using the screw driver……… likely a bad ing switch.
