I had hot start problem once. It started great when cold, but would not
when hot. My VW guy did not find out why. That's when I turned into a VW
mechanic for Vanagons.
Turned out to be the same reason what the fuel pump did the other day when
it worked for twenty minutes and then stopped working. And it should be
expected after this many years of service.
Or the same reason why the alternator did not charge the other day.
It is the Length of the BRUSHES that supplies the power to the motor. Or
the lack of it, rather. It has gotten to the end of it's length where the
spring is not able to press it down anymore. Thus there will be
intermittent starting for a while then nothing.
I bought brushes for a few bucks and installed, and now it works for the
last ten years.
Lots of money has been spent on new alternators, new starters, new fuel
pumps (not that you can change the brushes in there), when the little carbon
brushes had to be changed only. And the money is made on the consumer again
when the old starters and alternators come back painted with new brushes and
sold for good dollars.
