I HAVE AN 02 GMC DURAMAX 60,000 MILES. LAST WEEK AFTER AN 800 MILE 1 DAY DRIVE I STOPPED ENGINE UNHOOKED 5TH WHEEL. RESTARTED AND PULLED INTO MY DRIVEWAY AND STOPPED. AFTER ABOUT 1 HOUR WENT BACK TO TRUCK TO LEAVE. ENGINE INITIALLY JUST SPUN OVER AND OVER WITHOUT EVER FIRING . AFTER SOME TIME TRYING IT FINALLY FIRED AND CRANKED. DROVE TRUCK ABOUT 5 MILES AND PARKED IT. AFTER 1 1/2 HOURS CAME BACK AND TRIED TO CRANK . IT WOULD ONLY SPIN OVER ENGINE WITHOUT FIRING. THIS TIME I COULDNT GET IT TO CRANK. AFTER SITTING OVERNIGHT CALLED DEALER WHO SENT TOW TRUCK AND TOOK TO DEALER. DEALER KEPT TRUCK OVERNIGHT 2 DAYS AND COULD FIND NOTHING WRONG. IT CRANKED EVERYTIME THEY TRIED IT. I WENT AND PICKED UP TRUCK AND AHVE DRIVEN FOR 2 DAYS NOW. 1 TIME DURING THIS PERIOD IT ALMOST DIDNT FIRE BUT FINALLY DID. I DO NOT THINK MY PROBLEM IS OVER. AM LEAVING IN 2 DAYS ON ANOTHER LONG TRIP. ANYONE HAVE ANY IDEAS OR SUGGESTIONS? HELP WOULD BE MUCH APPRECIATED. HOWARD (hupton@bellsouth.net)

This sounds really similar to another member's recent problem about not
starting. IIRC, it was suggested that there was a faulty check
valve in the fuel system. Hopefully someone else will be able to
provide a better answer before your trip.
