I have 2006 f350 diesel it acts like it's not
wow....the sky is the limit here....i LOVE the 6.0, it pays my bills :)....with that said..there are many possiblities, almost too numerous to speak of...first, i assume you can hear the fuel pump?..try opening the upper fuel filter housing and turning on the ignition key, if filter bowl fills, good!...when you crank it, is it cranking above 500 rpm? thats the minimum needed to start, make sure batteries are strong. when cranking, can you see the oil presure guage rise? does it have the right oil in it? your fuel injectors are driven by high presure oil, without base pressure (what your dash guage would read) the high pressure system has no oil to drive injectors "power stroke". if you have base pressure you really need to have a computer on it to monitor high presure oil when cranking, will need 500 psi just to fier then would jump up from there...it is also possible the FICM, or fuel injection control module has failed..this too needs to be tested with computer, needs to read internal voltages to make sure has45 volts..now the ficm may be covered under emission waranties still...that truck did come with a 5 year 100,000 mile warranty on engine and some componetns are 6 years, based on state sold in...back to the high pressure oil system, in 06 the vehicle had awhat called a snap to connect fitting, or STC. that connects the high p[ressure oil pump to the branch tubes that supply oil to the injectors..that too can seperate with age and cause a no start...it would be in your best interest after chdecking the basics to see you dealer...in comparison the initial diagnosis would be cheap (in comparison) and effective if trying to repair on your own...it will save you much hair on your head!! good luck, hope this helps you...very hard if not impossible to diagnose these without compuiter on it!
