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.

this is an oil pressure problem, either a sensor is not sensing enough oil pressure, or the high pressure pump is not building enough pressure(possibly leaking or head is leaking). this engine requires 450 psi minimum oil pressure at the injectors to actuate the injectors.

You have to replace the defective glow plug. You can test the glow plug without the test light. Just put a wire on the bolted end of the glow plug and connect this to the battery (+) terminal. Then, put a wire around the body of the glow plug and connect this to the battery (-) negative terminal. Hold at this position for a minute or less. Good glow plug will heat up.
As far as the wiring schematics, I will just describe
it. Your ignition switch is connected to the positive
terminal of the battery by way of the fuse in the fuse
box. From the switch it goes to a timing relay before
going to the glow plug terminals. The glow plug body
is screw mounted to the engine block which serves
as the negative terminal. So, as you switch your
ignition, it heats up the glow plug enough to give a
combustion of the atomized fuel in the cylinder piston
of your car causing it to run.

check the ecu of your , it may control your plugs,
or check also your spill valve in the injection pump and the timing control valve also in the injection pump.
