1953 Ford F100 6cyl will start and run fine but won't start hot

Possible the old starter is going. When it gets hot next to the engine the springs in side swell up with heat and it won't turn over the engine. That what happen to me with and old Cadillac I had.

That is very possible if it does not turn over.

Without knowing more how can anyone tell? Does it turn over and not start or is it dead until it cools off?

My old 68 Caddy would just sound like it is drawing power and very slow crank almost like the battery had very little juice then bind up and wouldn't move. After a few hours of cooling the car would crank over like it was new. Changed the starter and it was great. Cranked over every time after the new starter was installed.

Now you can get modern, gear reduction starters for older cars that draw a lot less power but turn the engine over faster. They also save a lot of weight.

solenoid on the starter that could be bad.

Thanks for all the responses, sorry to not include more detai,l its my first time ever posting, but when i use the pickup around town and turn it off when i try to turn it on again (still hot) it will crank but not turn on, sometimes i try it so much i drain the battery.... the condenser/coil answer is good and the Caddy answer also makes sense since it's the original starter... THANKS GUYS!

Full_of_Regrets I will definately look for one of those modernized starters the truck is 6V though, any suggestions where to buy? Thanks!

You would have to install a 12V system on there, which can be done.

-Marlino, i changed the condenser under the distributor cap and the coil, that seemed to fix the problem but thanks for your answer, definately worth trying if it happens again.
