will not turn engine over when hot Sign In

my car will start straight away when cold, but when it gets warm it will hardly crank engine over. if i leave it for 15mins it will spin engine, no problem. i have fitted a new starter motor and cleaned all leads, had battery tested and thats ok. this problem seems to have started since i had new head gasket fitted. i have only limited knowledge of engines and was wondering if timing could be out although car runs ok. any suggestions please.

this sounds like a frayed wire from batt. to starter, batt. terminals? look around, maybe it was rubbing on something, with less wire to run through the current heats it up making resistance , the hotter it gets the more resistance, you need clean, top notch connections

Have you ruled out an ignition switch issue or starter relay issue? Especially the starter relay. It's common for the bridge in the relay to get hung up or fail altogether in these vehicles.
