Starter or solenoid?
My 79 F250 has developed a rather annoying problem. When it's hot and I shut it off, it has a hard time restarting. This left me stranded on the scales once and jumping didn't help the issue. I think it's the starter binding up, but I haven't tried jumping across the firewall-mounted solenoid either. If the truck's cold or has a chance to cool off for a while it starts fine. Guess I could just start at the top and begin replacing parts til it works, but don't like the possible consequences of being wrong and stranded again. So what's the likely culprit here?

Thanks for the suggestions. I'll get the starter bench-tested tomorrow. And no, 79f2506.6l, it doesn't have headers. It's a pretty stock 460, or maybe 429--the sticker seems to have the code for a 360/390 so I'll look at the block when I pull the starter and see if I can at least find out what year the motor is...

Okay.* Got starter out over the wkend, parts store managed to test it, they say it's fine, after a long consultation with a parts book to find the right part #. This starter has a solenoid on it, and the s terminal has been jumped to the main terminal.* This thing sits really close to the exhaust manifold--couple inches max with the solenoid up toward the major heat.** I assume a stock starter for a 79 460 has no solenoid since its got one mounted on the fender...is it likely that the problem is heat affecting the starter-mounted solenoid?* When it stops working, it's like it's completely frozen--I get a click, but no turning of the starter motor.* Could I remove the solenoid from the starter motor and bolt the main lead from the starter motor to the lead from the fender-mount solenoid and not damage the starter?

When it won't start, check for voltage at the relay from the ignition switch. Could be the neutral safety swicth. Had a car one time same symptoms went though everything like you and discovered that was the problem. When they get hot there is too much resistance in the circut and the vlotage doesn't make it to the relay.
