93 940 turbo will not start when hot
I have a 1993 940 turbo. When it is cold, it starts fine and runs fine but once i start driving it around, especially on a hot day, it will not restart. The newest episode, it started to sputter and then would not crank or start. After a few hours and the engine completely cools down. It will restart and drive around fine like nothing happened.
I have recently changed the belts, spark plugs, wires, rotor and cap, oil change, and the fuel pump is about 3 yrs old.
Any help please. Can't have the wife getting stranded all the time, since we live in hot weather all the time.
Thanks

if it won't crank, then its a issue with the starter circuit, or the starter solenoid itself. If it cranks strongly but doesn't start, then you start looking at other stuff like what lev said, CPS, ignition power stage, etc.
Odd you say you've put 3 starters on it in 6 years, we're original owners of an 87, its still got its original starter, and I've never changed the starter on any of my other high mileage volvos either. Did you use A) real Volvo brand starter, B) OEM Bosch starter, or C) brand X from bigbox auto chain ?
the starter control circuit goes from the ignition key "S" pin ('start') to the park/neutral safety switch on the side of the transmission, then to the starter itself. next time it won't start, put your foot on the brake and put it in "N" (Neutral) and see if will crank over. if ir cranks in N but not in P, then odds are your park/neutral switch is conking out, and its just showing up when its hot.
