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.

Could be the Camshaft Position Sensor (CPS) again. Did you have it replaced by the dealer on the Ford unlimited recall ? It's easy to check...get under the front end of the truck and look up by the harmonic balancer (sits behind the main pulley) on the passenger side and you'll see a sensor (could be brown but I believe that one was the recall color, most likely it will be black) with two wires coming out. Is it secured onto it's mounting bracket ? Is the wiring plug snug into it's socket ? If so...it could very well be a defective CPS. It's not unusual. Any possibility your batteries drained to a point where it's not cranking out enough ? Also consider, you may have originally had a different issue besides the CPS.
SOURCE: where and how do you put a cam sensor on a Ford
Camshaft Position Sensor located above front crankshaft pulley. Use 10mm socket on 1/4" drive ratchet. Crawl under front of vehicle, disconnect electrical lead, remove bolt, clean timing chain cover area, install new CPS. About $27 at Ford dealer. On some years this is covered under a recent RECALL by Ford...after years of litigation.

Some of the Ford transmissions actually have an aluminum gear which will go out somewhere around 150 to 200 thousand miles. OR it could be really low on transmission fluid.

The first thing i would check is the Glow Plug Relay. Depending on your engine there should be (2 solenoids, or just one) sitting on the top front a little to the right of center. (right bank of engine that is) If you have 2 of them one should be smaller and it is the one furthest to the rear of the engine. It controls power to your glow plugs for cold start up. When you turn the key to the on position the 2 larger wires should both have power. When the ignition is off only one wire should have power. Check this if you do both these tests and only one wire has power with key on or off then you need to make sure that the key switch is sending power to the solenoid. Do this by checking the smaller wire with key off. It should not have power and then with key on it should have power. If this is good and test one is bad then the relay is bad. Note This is not true for the larger realy that sits furthest foward on the engine. The bigger one. This test will not work for it but it controls your intake heater. On another note: This is a timed circut and will "kick out" after about 1-2 minutes. In otherwords it does not stay on all the time that key switch is on it will for for about 1-2 minutes then shut off! Next would be your injectors are getting weak or bad and even your HPOP could be getting weak. or glow plugs in engine are out, In otherwords there are alot of possibilities causing your problems If you are getting a misfire code for your injectors then you may have some weak or inop injectors. Any way this will give you a pretty easy test for the most common failure which is the Glow plug relay. About 35-40 bucks at your local auto parts house.
