Anybody have any advice? I got a 2002 Ford F250 Diesel 7.3 Automatic. I drove to store, parked, turned it off. Returned 5 min later, tried to start it. Nothing?! Wont crank..nothing. Batteries are good, lights on dash are fine. I think it's an ignition thing? I checked all fuses under the dash, all good. Please reply with any similar experiences/advice, etc. Thanks!
