Seems like a low injector control pressure situation. You may see plenty of oil pressure on the gauge but the high pressure oil that opens the injectors is probably passing through a blown STC fitting at the back of the high pressure pump or something of that nature. Check for smoke out the tail pipe, if there's smoke, I could be wrong. If you checked the glow plugs (make sure you have 12 comming and going through the relay, just because it clicks does not mean it's working) than you more than likely have compression, the last thing you need is fuel. To get fuel you need high pressure oil. Your truck should have an ICP sensor on the right valve cover toward the front. You can back probe or make a breakout harness to pins... ok I don't know what two pins but there is only three. Anyway backprobe the sensor and see if you have more than .82V while cranking. If you do not, go to the IPR (injection pressure regulator) which is behind and below the turbo. It is a round solenoid valve sticking out of the high pressure oil pump. This valve will have the connector pointing down and toward the back of the motor in it's "weather protecting" position. You can rotate this valve by hand so the connector is easier to get to but don't force it and break it. You will then need to apply 12V and a ground to this valve. Do not supply the voltage for more than 120 seconds though or you could burn the valve up. with 12V to the valve see if it will start. If it will you may have a power supply problem to the valve. If none of this helps let me know, the rest of the troubleshooting is pretty involved.

I would like to clarify, and somewhat solve this issue. First of all the dealer is right about the regen. If the truck is going into regen and did not finish, then it will do the regen again and again and this excessive regen will cause fuel in the oil. Unfortunatly Ford did not add a parked Regen switch (too complicated for some users) so you will have to drive untill the regen light goes out. I know it's inconventant but that's part of the hassel you need to go through because Al Gore invented the internet and then warned us all about global warming. Anyway there are some other causes including porous cylander heads (this will show up in low mileage vehicles only), HP Fuel pumps, fuel sensors, injectors, lines, etc. etc. Since you both seem to have low mileage ask the Ford Dealer about the porous cyl heads and watch his face go blank. Is smoke comes out of his ears make sure his DPF isn't clogged and ask him if he needs to Regen. then tell him he has to run 30 mintues weither he likes it or not or he will get fuel in his oil. By the way you may also need to ask about an updated ECM reflash which could help this issue. Have a nice day.
