Question

I have a 1969 Camaro with a 327, 4 barrel carb, electronic points, new voltage regulator, new Delco starter, battery was checked and is in good shape, had the alternator bench checked and is ok. The car starts real good when the engine is cold. But after driving for some time and the engine is good and hot, she just won't turn over. When I turn the ignition I can here the starter click like it's getting fire but it wont even spin. After the engine cools it starts up fine. I've checked the ground and connections and everything looks fine.
I can't figure this one out. Any ideas would be appreciated.

It sounds like it's the starter that is overheating. I could be wrong though. If it is the starter, you can put some sort a heat sheild on it and see if that helps. Any one else know for sure?

I had a simular problem with my 67. I have a powerglide transmission. Sometimes to start the car I had to put the car in neutral and shift to drive a couple of times to get my neutral safety switch to engage my starter. If this works for ya replace the neutral safety switch.

it could be your starter soleniod or the contacts in the soleniod,when it gets hot it does make contact.

check the contacts in the starter soleniod, they may be shot. check the soleniod out also while it's apart

SB327,

You don't say wheather or not you have header's? If you do you are expierencing what is known a "heat soak" (very common in chevy's with headers or exhaust pipes close to the starter). The heat from the exhaust is causeing the windings in the starter to get hot and create a lot of resistance there for you solenoid cannot flow enough current to turn the motor over.

There are two different fixes for this.
1. You can install a heat shield around the starter to protect it some.
2. Or like I have, you can install a Heavy Duty FORD starter soleniod (MAD Enterprises sells a good,complete kit with a very good explanation of the cause, Mark Hamilton is a great guy to deal with) on you car.

This will cure the problem for ever.

Cool

i have a 79 camaro that has the same problem. the starter is new. it also has headers on it. i found that to be the problem. i will be putting manifolds on it soon. the headers are just too close to the starter and other sensitive parts. like it was stated on a previous reply, could be heat soak. hope that helps.

Thumbs up

Thanks for all the advice. I ordered a starter solenoid heat shield first this morning. I'll try that first.

Not starting when hot is being solved different ways. The Neutral Safety Switch somtimes will send current to the starter, but aparently not enough to crank the car.

A heat shield my eliminate the problem, but
my similar problem was fixed by replacing the
neurtal safety switch attached to the shifter
in the console. My car has an automatic.

Good Luck,

Make sure the battery cables are really,really,really clean,and the + cable at the starter is clean and tight.Chrck the ground cable.Just take the cables off and clean them,both ends.Never know,and it's free.
