Best place to get a diagram is the dealership, if that doesn't work go to parts store for chilton or haynes manual

Neutral start switch

No, the starter is grounded to the engine block, . The neutral safety switch, Or gear select switch, is the midpoint for the 12v crank signal from ignition switch to the starter solenoid.

Under the glove box. There is the motor and a cover. There is 8 or 10 screws, size 9/32 maybe? And three wires. Unplug the wires and take the screws out. Then it will fall into your arms. Oh yea, it probably has black insulated padding on it. That should unsnap in some places, and unscrew in others??? Mine is a 95

1998 silverardo brake lights won't work we are trying to replace the brake moducle but we can't remove the old one.

before you start changing things buy you a test light and check your brake switch at the top of your brake pedal, 2 wires power should be on 1 and when you mash the brakes power should be on 2nd wire ? also check fuses

Where did you check for spark? Unplug the coil wire from the distributer cap and check there by placing the end of the wire near something like a ground wire or head bolt while cranking the engine. Don't hold it in your hand. If you have spark comming from the coil wire but not from the cylinder wires then I agree with stevevpb. Very possibly the cap and rotor. A word of advice. If you decide to replace the cap and rotor and/or possibly the iginition wire set as well, use only OEM parts. Yes they are more expensive but many aftermarket ignition parts wind up costing you a lot more in the long run. I've learned that the hard way. An OEM cap will probably run you about 50 bucks; rotor, 20 bucks; wire set, 150 bucks. What a rip but hey, it is what it is.

I had this same problem & cause was an aftermarket security system that was disabled by previous owner but never removed & therefore backfed 14.5volts into ignition system over time & destroyed it.Fix is replace ignition control module,computer control module & ignition wiring harness,also I must add that reprogramming is also required for modules & both keys.Unless you know a GOOD GM mechanic who will do this on the side & get you the parts at his cost,this is a COSTLY fix at dealer $900-$1200,about 6-8hrs labor.
