Where did you purchase the CPS? Local auto part store ones usually don't work and can have you running around in circles. Must purchase from Ford or IH.

Find a different Ford dealer, you should be able top pick one up for $25-$30. You want to use Motorcraft or International CPS. Parts house ones are known to be bad out of the box.

We need the code. It keep saying the tach moved a little. How much? Does it sound like its turning over slow or is it normal?

Try unplugging the ICP sensor and see if it starts. It probably won't but it can't hurt to try.

the tach goes up to about 200 rpm and it cranks fine just no start

When my truck did this a few months back, exact same as you described. Cutting out and dying. Finally just died and would not restart, luckily in my driveway. Turned out to be the pigtail off my IPR shorting out. So check the wires or the IPR itself.

I agree with wezol5484; it could be IPR related. Make sure the solenoid and spacer are on the IPR, and that the nut that holds them is tight, also.

You can check the solenoid coil with a multimeter. It should read between 5 and 20 ohms. If you can get a spare pigtail, you can put 12 volts to the solenoid long enough to see if it will start; positive on the red wire, negative on the yellow with red tracer wire. I don't think I'd install an IPR on my truck without knowing for sure it was the right one and would fit.

Clay at Riffraff carries them: IPR / VGT Soleniod Pigtail Connector Repair Kit 94-07 - Riffraff Diesel Performance or you could maybe try a salvage yard.

Any DVOM will read what you need for this.

Unplug the IPR, put your meter to ohms and it should have a "short" function. To be sure, touch the leads together and see if it makes a loud beep.

Take the leads and put one on one pin and one on the other (of the plug you pull off the IPR) an see if the wires are shorted out together. If that's good, then take one of the leads off while leaving one on, and touch it to ground. If good, leave that lead on ground and check with the other pin. What you're checking is a short between two wires and a short to ground.

Check the connectors on the heads for burnt/melted pins and plastic. Since there is no smoke during cranking and your CPS sounds like its working, the IDM may have shut itself down if it detected a short. No smoke could also mean low HPO pressure (ICP sensor, IPR, HPOP, or leak)or no fuel pressure (Bad pump, clogged filter, empty tank, leak, etc). You had an IDM code for something so lets start there.
