No Start Diagnosis
I have a 2000 Ford F250 with the 7.3 Diesel engine. It has 297,000 miles. Beginning of last winter I started having to plug the truck in at night to insure it would start the next morning. Now I only plug it in when the temperature is cold. The other day I was driving it when it died on me and I couldn't get it to start again. The engine cranks over but still doesn't start. When I turn the key on you can hear the fuel pump, and the glow plugs seem to be as normal. There is diesel in it, so I know it didn't run out and is the problem. (Although recently someone ran the truck out of fuel 3 times) The code that I received when testing was P1293. My diesel mechanic suggested it was the camshaft sensor. But after reading more into it I think I might have a bad IDM module. Any thoughts or suggestions?

Usually indicative of a problem with the UVCH (Under Valve Cover Harness) or something associated with the harness, like a bad/burned plug, loose connection etc.
I hope he didn't suggest that after you told him the code.
Are you able to pull the passenger side valve cover and inspect the harness?

If you have a multimeter and know how to test Ohms, you can test the resistance to the solenoids. Over the driver-side valve cover, there is a 42-pin connector with a 10mm nut holding it together. Don't have your key in the ignition when this is apart. D Driver side - even-numbered injectors, P Passenger side - odd-numbered injectors.
