i have a 86 chevy k10 with a 4 speed manual. I will start the truck up in the morning with no problem. ill go for a drive to get it up to operatin temps and if i stop and turn it off but turn it back on with a couple minutes it will restart. BUT if i let it sit for 30 minutes or so and come back to start it up i dont get anything. NO CRANK !! the light willl dim though. if i let it sit for a little itll start right back up with no problems... i have run out of stuff to try. i have replaced the starter. heat wrap on the new starter, new positive wire to the starter and new ground from battery, cleaned ground strap from block. and cool tube around ignition wire to starter. i am gonna try the starter switch tomorrow. i am out of ideas please help. thanks.

 

Try to jump it and if that makes it start. If it does I would suspect the batt.

 

solenoid...sometimes they get sensitive to heat, i had it happen in my malibu when i first got it

 

I replaced the starter and the selonoid. And I put the heat wrap on the new starter because I thought it was gettin hott but the new starter had the exact same problem. I am gonna get a new battery today and there is a small part of the ignition wire to the selonoid that looks a little melted. I'm gonna solder a new piece on and try that.

 

be sure the pos. cable is away from heat also
