Car Hard to Start After it gets hot???

Hey guys I have another problem. I just finished building my 68 so I'm finding out all the kinks right now.

Question: When the car is cold it starts fine, but after it gets warm and I shut it off, it seems like the starter drags and doesnt want to start. But after it cools down it fires up easily? Something with the starter getting hot maybe??

Any input or suggestions would be greatly appreciated.

Thanks

Yep sounds like the starter needs rebuilding or replaced.

Or battery cables of a larger gauge. Ground cable on the engine should be on the block rather than the cyl head, if alum.

Re: Car Hard to Start After it gets hot???

I added a Ford relay and shorted out the starter. It is easy to do and eliminates hot start problems. The Ford relay is about $15. Your starter is probably fine. The Ford conversion will take a lot of load of the starter anyway.

Here is a link on the conversion.

How and why this Ford solenoid works is beyond me..... you still have to "pull in" the GM one in order to get the drive to engage the flywheel unlike the Ford starter that uses the magnetic pull of the field coils to engage it. I'm voting with the guy that says the starter needs rebuilt.

Are you running headers? Perhaps your just getting a "heat soak" on the starter motor.

My 67 RS 327...its a work in progress.

try a heat shield over the solenoid.

Re: Car Hard to Start After it gets hot???

I agree that it's probably a starter issue. I also like the suggestion about"heat soak", especially if you've got headers that are routed close to the starter.

You could try a heat shield, or perhaps wrap the headers in the area that's close to the starter.

it works becasue instead of using the small power wire that goes thru the ignition switch to kick the solenoid out, it uses the full battery power straight from thr + battery terminal to do it instead of the reduced voltage and amperage from all the losses from the battery, thru the firewall, thru the switch, back out thru the firewall, and out to the solenoid..
but this will only affect the way the solenoid kicks out- it won't help if the actual starter "drags" when hot. then you need a stronger starter motor.
but before throwing a starter and solenoid at it or converting to the Ford solenoid, i'd look at the battery cables, battery, and all connections. just adding bigger battery cables and making sure they have clean and solid connections can help a lot.

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?

Re: Car Hard to Start After it gets hot???

As i stated above bro have your starter rebuilt or go buy a new one. More than likely your starter is old/used and has been hot many times before and is now dragging when it gets hot resulting in hard/dragging starts.

My 427 was hard to start when warm. I replaced the starter & still had issues. I added a relay as well. Problem solved.

Re: Car Hard to Start After it gets hot???

Check your timing, make sure the headers are not heating the starter up too much, and check the CCA on the battery, I like at least 850, lots of cheapo batteries on the market with wimpy CCA's.

Mostly Camaros and FINALLY a Double Nickel
