Don't bother, all the Auto Parts Stores have are Generic OBD-II scanners and of little use for us.
Also, what year is the truck?
IF the two are related (and they might not be) then you have to go over Every Place you were. Something got "josheled" or disturbed. You may have had a marginal connection that got worse, and there could be Many of those. Look under the wiring harnesses, where they contact stuff like the ValveCovers or anywhere else, and lift them up & off to find a chafe-thru maybe. Were you in the fusebox at all? Could something there have gotten disturbed? What about the connections to the injectors through the VC gaskets?
Maybe it's just coincidental this happened, here's the regular No-Start list I think of;
Do you have a spare CPS to try? (they'll do that to ya, die while running down the road but, will often restart after a rest)
Does the WTS light come on? (shows the computer is running)
Is there fuel in the fuel bowl now? Does it refill after cranking? (open the drain level to check)
Could the fuel gauge be giving a bad reading? (are you close to empty?)
Is it cranking fast enough? - it won't even TRY to start if cranking really slowly.
Is your truck "chipped"? If so, remove it as a Test. (this means REMOVE it, not just turn it to the STOCK position)
Next, you could try disconnecting the plug on the ICP sensor to det a default value for the IPR to run with. Did you check the plug and sheet metal nut going to the IPR? That nut can vibrate off and allow the solenoid going over the valve to slide around. The wires going to the IPR can get brittle, crack, and short together. Make sure the plug & wires look in good shape. Try "rapping" on the IPR with a screwdriver handle, sometimes if stuck, you can "free it up".
