Hot cranking issues.

Hello everyone of the forums, I seem to be running into a hot start issue with my truck, if i go out and do some driving and get her up to temp and say pull off to a gas station it will sometimes start fine but I have been finding that some days she does not want to spin at a reasonable speed to let the engine light off. Last time it did this I floored it until it started to crank at a decent speed, stopped, then put the throttle in a bit and go it to finally fire up and come back to service.
As stated it is rare but if there are any tips or ideas on what I can do to help avoid this issue so it doesn't leave me stuck at a bad time I'd greatly appreciate it.
Thanks in advance, Shadow.

Mine has a similar issue go drive it like a teenager who doesn't pay for gas for a bit and park it somewhere (preferably home) and see if it will start up if not it has an overheating starter mine is caused by having exhaust manifolds that are meant for a car with a 157 tooth flywheel due to a motor swap

I have the same problem with my 88 F150 with a 302. I have never figured it out but Willz might be on to something. I'll have to check the starter temp the next time it happens.

What size flywheels do you guys have and do you have headers or different exhaust manifolds

And do you have a stick or automatic

Haven't had the chance to drive it yet but Mine is a 302 5speed Mazda tranny and has a set of flow-tech headers.

To shadow it seems like your headers are the cause and the manuals all came with the big flywheel in the trucks as far as I know. I got a set of truck exhaust manifolds to put on so it should fix it all I can say to 88xltlariat is check the exhaust manifolds for casting numbers see if they're off a car

Yeah the starter overheating due to the header is the issue, my fix to it is to let my E-fan run with the truck at idle not for about 15 seconds prior to shutting the engine down, that has helped it considerable.

I got my exhaust manifolds swapped to truck ones i expected them to be wider but they weren't so I don't have high hopes for it

Crawled under the truck yesterday to find that there was no heat shield surrounding the starter. The current exhaust setup is not stock, therefore, I think the previous owner discarded the shield when changing the exhaust. This truck (1988 F150 with 302) did have a shield from the factory, did it not? Well, I have a sheet of titanium and I'm going to fabricate some shields to reflect any heat and see if that resolves my issues. Thanks for all of the input.
