Check "main" relay under dash by fuse box. Easy test (in quiet environment)... (1) turn key on til dash warning lights illuminate (2) watch 'check engine light', should here a click when light goes off . when the car doesn't start would be when you don't here a click when the light goes off. DON'T crank while watching light. Main relay is for fuel pump and can be 'heat sensitive'.many a fine distributor have been replaced because of this $#$^%^#% relay.
