Would not start... or even click

[kjhansen]

Hot day here in Missouri--about 90.  Just tooled around town with a/c on.  Coolant temp didn't go over 190.  Stopped at a body shop to see if they could adjust the driver's side window.  Then car wouldn't start.  It wouldn't click or make any noise.  Scanmaster said there was 12v from the battery.  Tried jumping across the starter, which spun the motor but didn't engage the bendix.  Poked around under the hood checking for loose wires... none.  Looked under the dash for bad fuses, lose wires, etc., and no problems seen. Tried both Park and Neutral, wouldn't start in either one. Worked on it for 30-40 minutes.  Finally gave up and called my wife to come and get me.  Got in the car and tried to start it one more time and it fired right up. 
I've owned another TR before and took it to San Antonio, TX with me for 3 years.  It gets hotter in San Antonio than it does here and I never had a heat-soak problem there, and it was my every-day driver and Friday night drag racer.  Of course this is a different car and I don't know how old the starter/bendix combo is.  I do know that it's got a 3" downpipe that goes fairly close to the starter, but so did my old car.
Anybody have any problems like this?  Won't start when it's really hot?

Also, different topic, I put a new regulator and motor in the DS window a while ago.  The old one rolled up and down with jerks and bumps and wouldn't close all the way if the door was closed. Now the new one rolls up and down jerkily and won't shut all the way if the door is closed--which was why I was at the body shop in the first place. They lubricated the rubber seals, but that didn't help.  Any thoughts?

sounds like you jumped between the wrong two posts.  Should be between the small nut with the purple wire attached to it and the big post that the battery cable hooked to it...but if that is where you tried..then it sounds like the solenoid was hot and refused to do its job.

It never happens when you are at home and can get to it...a volt meter connected to the purple wire terminal and ground should go to 12 volts when you turn the key to start.

I'm guess it's time for a new starter without other input.

It was actually a mechanic at the body shop (they do mechanical work too) that jumped the starter motor.  Put a jack under the frame and slid right under with no jack stand.  Braver man than I am. 
At 71 I don't crawl around under cars anymore.  
Anyway, I went out to the barn just now where I parked the car, and it cranked right up. 
Hmm. 
I'm ok with a new starter motor, but does anybody sell a heat shield to go on our cars?

I don't crawl much...  I mainly just lay there and wish someone would come by and pull me out LOL

I ordered a heat shield from Jegs.  We'll see if that helps.

Steve is hilarious!! LMAO. 

In regards to the heat, I stay in MO as well and I have never had that issue. As long as I've had my car, I've never changed the starter. It's the original for sure.

It's not normal. I love in a much hotter area. I guess a tired solenoid

Phil, when you get older, you will appreciate the feel of cold concrete under your back on a hot day.  It's also a lot easier on your back than standing up under a lift and reaching up.  I would like to say I wiggle out like a snake, but, it's more like a bowl of jello shaking in an earthquake...I move, but pretty darned slow as I emerge and I look for something to grab on to in order facilitate getting vertical.

Yo!!!! Lmao, the detail you provided was very in depth. I watched it all play out. Lol. The snake and jello did it
