OK HERES THE DEAL. I WAS DRIVING HOME FROM WORK AND I LOKK DOWN JUST IN TIME TO WATCH MY TEMP GAUGE SPIKE ALL THE WAY TO ABOUT 250. SO I STOP ON THE SIDE OF THE ROAD TO FIND THERE IS A CRACK IN MY RADIATOR, IT SEEMS THAT THE THERMOSTAT LOCKED UP. SO I GET IT HOME JUST AS IT PEGS OUT AGAIN... THE TRUCK WAS STILL RUNNING WHEN I GOT HOME. BUT THIS MORNING IT WOULDNT CRANK IT JUST KEEPS TRYING TO TURN OVER LIKE IT WAS FLOODED. NO RESULTS FROM ANYTHING I TRIED. ANY IDEAS AS TO WHAT THE PROBLEM MIGHT BE? PLEASE DONT TELL ME I BURNED A PISTON OR SOMETHING THATS GOING TO TOTTALY RUIN MY DAY!! LOL ANY HELP WOULD BE GREAT. THX

 

Get a compression test to check for fried rings.

 

UMM i think you got REAL PROBLEM, try reseting the PCM and if you get REALLY LUCKY it might start. sounds like you cooked the motor. DOnt you wish you would have called a tow truck

 

reset the pcm (disconnect the battery for 10 mins) and try again. if that doesnt work, pull the head and check for burned rings or pistons. how far of a drive was it when it was pegged out? these motors are pretty tough, it shouldnt be tooo bad of damage.

 

Check your coil also.
