my car starts great but when it gets to operating temp. i shut it off and will not turn over. once it cools down, then it starts right up. i have new battery cables, fully charged battery,new alt,new starter relay,new voltage regulator,new mini starter,new timing chain and gear, the timing is set at 12*btdc, it is a stock 302. i added headers and a 4bbl. im stumped, any ideas?
Sounds like heat soak at the starter or high resistance in cables. What size battery cables? Did you try mor than one starter?
Ed, I too use the mini-starter. I bought it at Vato Zone (application: '92 Mustang 5.0). When I was having trouble with the starter/flexplate engagement, I took the starter back for an exchange. I told what was going on and they gave me a replacement without hesitating. The starter is one of the easier items we can R&R on 302's. I'd try talking to the Parts Counter guy (where you bought the starter) into exchanging starters - for starters. (I just made a funny!). Good luck and keep us posted.
Does your Ground cable go to the engine or frame? You have to be sure the engine has a good ground - At least #2 wire. The cables to the starter and solenoid should be#2 as well. #4 or #6 iscommon but they have more resistance than you should have, especially with the reduction starter.

Sorry. I didn't mean to imply your starter wasn't engaging - just that it might be getting weak. Replacing it (for freebie) would eliminate that variable.
i would say starter , my dads truck was just doin the same thing, it would fire up on the coldest of days then , driving it for a while then it would warm up and it would not start , sounds just like what your problem is , but just my .02 but
i had my stock starter checked at auto zone.they ran it through 5 cycles checked fine every time. remounted it still did the same thing. funny thing is it didnt do this untill i added headers. i figured i would get a new starter anyway.got a mini starter(e-bay) still does the same thing. do i have to have a ground from the engine to the body or frame?
If headers brought about your problem, then it is heat soak to some degree. Did you make sure you had 2ga or better cable? Is your battery in the trunk? Do you have some header wrap laying around that you could shield the starter with? Does retarding your timing a bit help? (I know you have it right at the moment, but I was wondering) Dave
If they check it like most places, there is no load put on it and certainly no heat involved. Its not really a valid check under those conditions. I'd agree with grounding and cable size issues.
Yes you should have at least the neagtive cable and another ground wire of similiar size from motor to body.
fixed after all of this work.it turned out to just be the battery.saturday morning i warmed the car up,then turned it off. would not start.hooked up the battery charger for about 10 min. started right up. turned it off again,again it did not start. my neighbor brought over a new battery,fired right up. so i bought a new battery saturday morning been working fine since. this morning i drove it around the neighborhood shut it off started right up. never thought about the battery before because it always started the first time. boy do i feel like a dope.
Rick, I have been looking to get a mini-starter for my 250 Maverick to help with header to starter clearances, and I'm pretty sure that the 250 and the 302 take the same stock replacement starter. That would mean that the mini-starter you are using should fit my application with a C-4 tranny. Did you really mean Auto Zone? Do you happen to have the part number handy? Thanks.
