2003 6.0 4x4 6 speed 80k mls. Driving down the highway with the cc set the "check guages" light came on. The oil pressure was at zero. Coasted into a rest area, tried to start it, it spit and sputtered a bit then nothing. It'll crank all day but no fire. The first shop (after four hours and $250.00) said the high pressure oil pump was bad and for $2200.00 they would be obliged to replace it. I had it towed to the local dealer. They have been working on it for four days and still have no idea what the problem is, they have changed the oil pressure regulator with no results. Now they are going to look into the injectors. Any thoughts????

 

my 2003 6.0 towtruck did the same thing three days ago....they gave me the same speach and it is to be back today...i guess i will see ...will repost a reply when i see it running again

ok truck is back intake was pluged solid,new oil pump up top and a injector pump tootal bill was $3400.00 beans,seems when the oil pump fails the injectors go flat and it took the injector pump with it for a laugh :{ hope this helps
