Ok, you can unplug the ICP and crank. It will default to a "safe mode" but will crank. You can also look at the top of the sensor and see if it is leaking oil. Won't be much, but sometimes when they go bad, they will have a little bit of oil under the plug. The IPR is not so easy. Other than checking the tin nut on the back and the wiring harness, the rest will require a code reader or better data tools.

Lots of things can cause your problems such as low oil, HPOP draining down, dirty oil, weak batteries, dragging started and these are just the simple one to check. Bad ICP and IPR are more difficult to find and repair. Make sure the first ones are good and we will go from ther

Did I read that the truck starts fine if you plug in the heater? If so, you have a GP system problem. Nothing to do with the IPR or ICP.
If so, have an assistant, one of you jump the large terminals on the GPR for about one minute, and then the other person can turn the key and see if it cranks. No need to be in the WTS mode while the person is jumping the GPR. Just turn there for about 5 seconds to build fuel pressure and crank it.
EDIT: Also, does it show any oil pressure while cranking when it does not start?
