Engine Mechanical problem
1976 Chevy Monte Carlo V8 Two Wheel Drive Automatic

The car cranks fine when cold, first turn, no hisitation.
After running and heating up, the car will not restart. It will turn over and seems like it wants to start, but just will not start. I tried leaving it for an hour and it still would not crank. Left overnight, then it cranked without problem.

When this happens do below and see what's causing it -fuel or spark issue ( ICM or Fuel Pump )

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it
