1991 240 hot start problem

I think that I'm having a starter problem (again!!). On hot days
(mid-90's and above) after the car sits for 20 minutes or longer, it
won't crank. If I leave the key on and jump the connections on the
solenoid and starter motor, it will spin the starter. Then I can start
it with the ignition key. It's got a new neutral switch and the starter
is less than one year old. Is there any other possibility or should I
just drag out my wallet and buy another rebuilt starter? It's a high
dollar enough item that I'd hate to replace it and discover that it
wasn't really the source of the problem Thanks.

 

Have you tried swapping a different battery into the car? I realize hot
starter problems are more often the starter itself, but I think the symptom
you have of working after you bypass the switch stuff suggests the battery
can't get the motor out of stall. Anyway, swapping is cheap and easy enough.

I would say if the starter spins when the connections on the starter are
jumped (Assuming that the "jump" is from the big wire to the little wire
on the solenoid) then both it and the battery are OK. The problem would
be in the neutral switch, ignition switch, or the associated wiring.
