The car will crank, but will not start. Sometimes it *might* sputter,
but that is about it. If I open the hood and let it sit for 10-30
minutes, it will start just fine and run all day long again (until stuck
in traffic)
I have confirmed and can duplicate the problem. I can drive around, come
back home, and let it sit in the street idling. After just a short
while it will die every time. It will not start until it has cooled.
So, if I try a 'supposed' fix, I can verify if it is truly a fix or not.
Any thoughts?
The intermittent electrical possibility was my first thought; especially
in this day of semiconductor ignition. I had thought about a vapor
lock, but then why did it start happening and also happening with
consistancy.
I was concerned about the "let's try this" type of solution. That is
why I tried to see if I could duplicate the problem every time. If
something is changed, it is very quick to discover if the change was the
solution.
Try changing out the ignition coil.

In both cases, in my 280S and in my power boat, the problem was resolved
with a new ignition coil.

Afterwards we also found out that one of the engine fans had been
incorrectly wired and was spinning in reverse, not cooling the engine
at all.

That must have been a bad connector. Wires don't go bad unless broken or
the insulation is damaged.

My engine is not overheating. The temp gage is in the normal area. The
problem is heat buildup in the engine compartment that is causing some
component to overheat.
