Your problem is the Crankshaft sensor Ford had some problems with these it is located on the front of the motor by the Harmonic balancer

Try jumping it, sounds like the battery can be dead. But there is a solenoid on the firewall I believe the left side inner fender (in the engine compartment) you can turn the ignition on and jump the two leads with a screwdriver and see if the motor turns over. Remember this is a huge motor with high compression and the glow plugs have to fire to start. Takes a lot of juice to get it going (thats why it has 2 batteries). Make sure you have charged batteries. If not charge/jump the truck. The starter can only be tested off the truck, a solenoid if bad only cost a few bucks ($20-$30) but they don't fail too often

Hope these help

The Ford 7.3L diesel engines require a LOT of power to crank them over. The FIRST thing to check would be the battery and battery cables. If you are absolutely certain that these are in good condition, then you must check for power coming from the starter relay (mounted on the right fender apron) to the starter solenoid (part of the starter assembly)The "click" you are hearing is either the starter relay or the starter solenoid, or BOTH at the same time. If the starter relay is providing the correct power to the starter solenoid, then the starter assembly must be replaced. If the starter relay is not providing the correct power, then most likely the starter relay is bad.You just have to check for the proper current at the proper places and the problem will be found.Please note that your truck is also most likely equipped with 2 batteries. One battery being bad can cause BOTH of them to not work properly. So when you test your batteries, it is best to disconnect them and test each battery on its own merit.

trottle position sensor is on the trottle body opposite the throttle cable

yes their will be a fuel shut off safety switch but where i have no idea ,sorry iam a europeon mechanic and never seen this vehicle before ,although i have worked on the camper van model of this vehicle ,7.4 litre petrol engine this one with autobox but it had a gas conversion or the owner couldnt afford to run it .

Intake Air Temperature Sensor (IAT) - REMOVAL & INSTALLATION

5.8L and 7.5L Engines

Fig. 5 Typical IAT sensor mounting-5.8L and 7.5L engines

1. Disconnect the negative battery cable.
   
2. Detach the electrical connector from the IAT sensor.
   
3. Remove the IAT sensor from the intake manifold.

On California emissions equipped models, the IAT sensor is located in the air cleaner-to-throttle body tube.


To install:

1. Installation is the reverse of removal. Tighten the IAT sensor to 12-17 ft. lbs. (16-24 Nm).
   

7.3L Diesel Engine

1. Disconnect the negative battery cable.
   
2. Detach the electrical connector from the IAT sensor.
   
3. Remove the IAT sensor from the air cleaner housing.

To install:

1. Installation is the reverse of removal. Tighten the IAT sensor to 12-17 ft. lbs. (16-24 Nm).

Except 5.4L Lightning

Fig. 8 ...carefully twist the sensor from the air cleaner outlet tube

1. Disconnect the negative battery cable.
   
2. Detach the electrical connector from the IAT sensor.
   
3. Remove the IAT sensor from the air cleaner outlet tube by carefully twisting it out.

To install:

1. Lubricate the IAT sensor opening in the air cleaner outlet tube with a suitable lubricant such as a penetrating oil.
   
2. Carefully twist the sensor into the tube.
   
3. Attach the electrical connector to the IAT sensor.
   
4. Connect the negative battery cable.

5.4L Lightning

Fig. 9 Typical IAT sensor mounting-5.8L Lightning

1. Disconnect the negative battery cable.
   
2. Remove the front EGR vacuum regulator bracket assembly nut.
   
3. Remove the EGR vacuum regulator bracket assembly bolts.
   
4. Remove the rear EGR vacuum regulator bracket assembly nut.
   
5. Detach the barometric pressure sensor electrical connector.
   
6. Disconnect the vacuum lines and detach the electrical connector from the EGR vacuum regulator and remove the regulator and bracket assembly.
   
7. Disconnect the supercharger bypass vacuum solenoid vacuum lines and detach the electrical connector.
   
8. Remove the solenoid.
   
9. Disconnect the differential pressure feedback EGR (DPFE) exhaust pressure lines.
   
10. Detach the DPFE electrical connector and remove the DPFE sensor.
    
11. Detach the intake air temperature (IAT) sensor electrical connector.
    
12. Remove the sensor.
    

To install:

1. Installation is the reverse of removal.

If your check engine light is on it could be multiple things. I would first start with your oxygen sensor though since that is what it sounds like is the problem to me. Let me know how it goes!!

Did you pull the PCM connector? See if the short goes away.

Pull the computer, the little box in the kick panel (I think), unplug it, plug in the 20 amp fuse and see if it blows. If it does, the problem is from the battery to the PCM feed or one of the powered circuits.

If it doesn't, the PCM is shorted internally. Lots of floating grounds under the hood of the tour to fool a meter. try to look some CD or Workshop Manual to check the right wiring diagrams from Ford. I've rewired cars that had melted harnesses and found lots of incorrect diagrams.

SUMMARY:
You either have a short in the power supply wiring to the PCM, or ain internal short in the PCM itself. Inspect the wiring, disconnect the PCM and turn the key on. If the fuse blows, the problem is in the wiring. If the fuse does not blow, the short is in the PCM.

Hope this helps.

The pump may still be weak due to lack of power. Remove the relay and inspect the terminals to where it is attached. There may be corrosion or the relay may be bad. These issues may prevent the pump to work correctly. Otherwise it could be a weak pump.
