Hey guys/gals, my first post! I had my engine rebuilt a couple years back and I still have a nagging hot start problem even with the rebuilt starter. My cables and wiring look fine and I have the heat shields on starter and solenoid. Thinking of buying a High torque starter. Will this do it?
Thanks Ed (newbie)

I've had the same problem on a couple engines of mine. It never seems to be the same thing twice.

You have done most of the preliminary checks, but don't forget that the ground connection to the starter needs to be good also. Most people will check the positive cables and then forget the negative side.

A high torque starter will help if not solve the problem. Be carefull what type of starter you buy. I bought one from Summit and because I was using the HO manifolds it would not fit, it did fit with headers. Some allow for this by letting you rotate the motor/solenoid on the mounting block. You can even buy some that look stock.

I had a similar problem with my 389 tri-power.
It would always start cold, when hot it wouldn't
even turn over. After new battery, rebuilt starter,heat shield and then a high torque starter,I still had the problem. It was a wire going to the alternator that was almost broken in two.I replaced the wire and Voila, it starts fine now.
Hope this helps.

Don't forget your main grounding straps. You can fry a lot of electricals when the engine/frame/body grounds are worn out, dirty, or gone. Most people think the bolts that hold everything together are enough, but those grounding straps and wires are there for a reason. Without them, the flow of juice is changed and all that hot amperage ends up in other parts of your starting/charging system. Sometimes it can mean frying starters, alternators, distributors, and other stuff.

dallas, very good point. I saw a young man with an RX-7 fry two temp guages because he had no engine to body ground. Electricity will find a way to get where it wants to go. He's just lucky it wasn't something more expen$ive.

This is what worked for me in regards to the hot starting problem:

New battery cables
Delco 1000 CCA battery (installed in 1995)
Heavy duty solenoid (part# GME100C, from PY, $35, installed a few weeks ago)
Solenoid heat shield

I have an otherwise stock Delco starter, with a NAPA starter drive that I installed a few years ago. This is the same starter that was on my car when I bought it 7 years ago. The car starts fine (stock 400, 350 horse, stock exhaust manifolds, '68 GTO), hot or cold, with the above equipment.

Try the heavy duty solenoid and spring; I'm sure that'll solve the problem.

I solved my hot start problem with a kit from Mad Enterprises, called "Startem up kit" it consists of an additional solenoid to be installed in the start circuit. Once installed I have not had any problems.

Is your car sitting too high?

Sometimes if the car sits too high, the thinner air will prevent the starter from turning over when its hot.

Ed,
I had the same problem when I first got my car. When that temp gauge hit 200 or better you could bet the house she wouldn't start until it dropped below that.

My "former" mechanic couldn't believe his rebuilt starters wouldn't kick it over but after FIVE I had enough and bought a Powermaster high torque mini starter. Beautiful unit, almost too pretty to put in, but I did. Anyway the problem stopped immediately. You could hear the difference in the way the engine turned over. Before it dragged, like the starter was pulling it. With the new one it was almost instantaneous, like it was shot out of a rocket or poked with a cattle prod [img]smile.gif[/img]

As others have pointed out a lot of things could cause this but in my case there was no doubt. It was money well spent. It's embarassing not to be able to start your car especially when 3 or 4 admirers are standing by. I would have paid anything to fix it.
Good luck,
Bob G.
