<VV> Maybe the starter.

[Jim Becker]

You asked a question on a subject that you admittedly know nothing about "I 
would like to know why this happens - all I know is it DOES happen." 
Several people replied with reasonable, well thought out explanations and 
proven fixes based on their first hand experience.  You have chosen to argue 
with everyone's explanations.  This is in spite of your initial claim and 
subsequent demonstration of no knowledge on the subject.

Do you ask questions just so you can find someone to argue with?

Too bad our Delco starters aren't made in England.  Then, rather than 
failing when hot, they would fail at random and you could fix them with a 
hammer.

Are you saying a hot engine is harder to crank than a cold one? Thats a
novel concept. Unless it's on the point of seizing of course!
