STARTS FINE COLD. RUNS GREAT. AFTER WARMED UP AND SHUT OFF IF YOU LEAVE TRUCK SIT FOR 10 MINS IT WILL NOT RESTART. IT WILL FIRE FIRST TRY AND DIES OFF RIGHT AWAY LIKE IT RUNS OUT OF FUEL. YOU CAN THEN CRANK ON IT LIKE CRAZY BUT IT WILL NOT START. IT DOES THIS FOR 20 MINS OR SO AND THEN FIRES UP AND RUNS PERFECT. NO CODES OF ANY KIND. FUEL PRESSURE IS GOOD. HAVE INJECTOR PULSE AND SPARK WHILE NO START. CRANK SIGNAL AND CAM SIGNAL BOTH LOOK GOOD ON THE SCOPE. CAN SHOOT ALTERNATIVE FUEL IN IT AND IT REALLY DOESNT AFFECT IT. IT WILL FIRE RANDOMLY BUT NEVER START. IM AT A LOSS. UNPLUGGING THE MAF MAKES NO DIFFERENCE. ONCE IT STARTS YOUR GOOD AGAIN UNTIL YOU TRY STARTING HOT. NO MISFIRE ON START UP. DOESNT SEEM TO BE FLOODED. EVRYTHING I CAN THINK OF LOOKS GOOD WHEN IT DOESNT START.
