Tom,
Coolant temperature sensor, located near the waterneck on the intake manifold, 2-wire harness. Tells the computer how warm or cold the engine is and adjusts the A/F mixture accordingly. This might be it IF by saying "won't start" you means it's cranking just not turning over. IF it's not even cranking while hot, starter & wires are likely heat soaked.
