My '93 Ford Ranger died on the road three days ago. The motor simply stopped. Battery is good. the engine will crank but it will not engage. Had it towed to my Shade-tree mechanic he is puzzled. Says that trouble code 5931111111 indicates an air conditioning problem but that doesn’t make any sense. Does anyone have any Ideas? The truck is 4 cylinder 2WD.
