Also posted in the tech help section. If I stop the car for a few minutes, the starter won't spin until the car has cooled down somewhat.

I'm sure someone here posted about this a year ago or so, but can't remember the outcome.

And don't get me started on the "search" function here...

 

pretty sure its a knackered starter/solenoid. When the car is cold, it has less compression than when fully warmed, so its harder for the starter to spin over. i think

 

Yep been doing lots of reading, looks like solenoid sticking when hot. Luckily I have a spare starter kicking around, just hadn't planned on lying on the dirt fixing my car today!

 

Just put a hammer in the car mate

 

LoL, don't worry, I've gotta go out in a bit, gonna take the spare starter, and a hammer, as a survival kit. Just really really don't want to get mucky today, life is too short!

 

Volt drop it all and you will find the problem!!!

 

had exactly this problem with an old astra years ago.changed the starter motor. when it had the problem if you rocked it to & fro in gear, it would start every time.

 

I'd check the wiring to the solenoid first - I bet there's a corroded/dodgy joint in there
