Okay, the auto TGP I bought last February is finally getting some attention.  The first thing on the list is to get the starter situation resolved.  I'm going to pretend that the p/o didn't try anything.  (He used j/y parts N such to test w/, I don't believe in that  :D )  So, here goes.  The car has a hot start problem.  I should say had, because as of recent it will do it upon 1st startup as well.  No click, nothing.  So, the p/o wired up a jumper wire for the sol.  You used to be able to start it w/ the key no problem, until it got hot.  Now, you have to use the wire on first start, then you can use the key until it gets hot.  Follow me?  So, where should I start?  Here's what I'm thinking:
1) Neutral safety switch 2) Ignition switch 3) Harness

Now, if the ignition switch were bad, or the NSS would it not allow it to start, do to the nature of the switch?  Or would it still ALLOW it, just not request it when it's supposed to?

Jud, I saw your post on how you fixed yours, but didn't really understand it.  Could you elaborate please?  Obviously the first thing to get replaced is the starter.  I want to go w/ a 3100 Mini High torque anyhow, so that's where I'll start.  Then go from there.  

A side note that may or maynot help.  The p/o's conclusion is that there was a voltage drop in the harness somewhere, and when it got hot, it opened the circuit.  He thought that maybe a sol. w/ less drag would be easier on the circuit, but I think it's just engine heat and not current heat defeating the system.  

Okay, guys, any help would be appreciated.  I plan on getting my switches this weekend, and getting this puppy fixed.  My laptop will be here next Wednesday, so I would like to get her ready for the track next weekend.  I've got a few other situations to fix, but those will be easier w/ the laptop and my ALDL cable.  TIA.

I had the same problem with my car. You'll turn the key over and nothing...I would have to go under the  hood and tap the starter wire for it to turn over. The all of a sudden it wouln't do it with the wire eather. So I started it on the starter selinoid. Turned out to be a bad contact with the selinoid wires and ground.

I'd test the swtiches with a small blower motor (witout the blades) or use the rad fan by unpluging the pos wire and running it to the selenoid wire. I'd disconect the starter selinoid wire and put the fan motor there. Then crank it. The fan should start. Both in P and N.  If it does..your starter is bad or had bad contact.

If not..bypass the safty switch on the trans and plug the fan to the thick Yellow wire (or the purple?)on the safty switch harness. Crank it and it should start. If it doesn't..then your Ign swithc is bad. If it does start...then your safty switch is bad.

I hope that atleast helps.
