Default Won't start hot

1990 c4 manual trans, stock. When engine is cold, car starts right up. Drive until hot, stop, won't start. Battery light goes on along with check engine. After it cools, both lights go out and starts.

Any ideas?

Thanks!

Can you give some more information?

Does the engine spin? Does it catch at all? What does your temp gauge say on the engine?

BTW... CEL and BAT light are on normally as you are trying to start the engine and/or until it catches.

Sorry. Engine won't turn over. Battery shows 12.8 volts. Temp gauge in middle of range which is normal for car.

Thanks for info on lights; had no idea!

Found "heat soaked" starter under search. Sounds like the problem. Comments?

I do hear faint solenoid click when trying to start hot.

That,s where I'd start; You got to get her spinning before you can diagnose anything else.

I have the same problem. Have replaced the starter, no effect. How did you solve your problem?

Load test your battery clean connections both sides and behind the bolt check cables and clean jump box behind the battery if you have one.

Much better starter that you cannot find anymore and much cheaper.

Depends on what you are trying to achieve. If you want a high torque starter, probably have to buy a new one unless you can find an old core. If you get an Autozone one, well.... it is going to cost you less up front but maybe not cheap in the long run. If I was getting a stock one, I'd have it rebuilt so I have some control of what goes into it as opposed to something you put in and sell me shipped from the middle of BFE.

Did you have the starter taken apart and visually tested or how did you determine it was bad?

When I first installed the brand new AutoZone (lifetime warranty) starter, it worked cold, but not hot. Then it wouldn't even spin the engine cold. I tried everything else, assuming the new starter was good, but finally jumped across the battery lead / solenoid terminals, and nothing happened. Considered taking it apart, but since it was warranted, pulled it out and got another one. This fine red convertible is back on the road now........and looking good.

Lifetime warranty is so you can feel good about buying a store brand. In reality, I wouldn't get one since I don't think it will "go the distance". It just means you will pay to have someone install it again whether it is you (your own time) or someone else. Kinda like Wal*Mart. Sure, it is OK to buy Mobil 1 oil since it is a known quantity. I wouldn't buy their store brand of anything. For me, the aggravation isn't worth it. I'd pay more to get a known good company or have someone rebuild it that you can trust. Even if you paid for the labor and parts, it isn't fun getting stuck somewhere in the middle of BFE. Good luck. Next time it fails, forget the warranty and get something good.
