The relationship between the Instrument cluster and the PCM is the 5 volt reference circuit. Even the battery saver circuit failing in the instrument cluster can cause a no-crank. If the battery saver circuit is bad, it can cause a total loss of electricity (lights, horn, ignition, dash, fuel pump, starter, etc) or a partial. Just turning on the head lights for a few seconds can sometimes return the proper operation.
Often times fuse F2-22 is a culprit of a no-crank, but not necessarily the main cause. Most of the time F2-22 "pops", there is a problem that causes it!
In addition to a bad instrument cluster, a shorting out fan clutch can cause the no-crank, but will not impact the mileage and fuel economy display. Same w/ some of the 5 volt engine sensors. Disconnection of these can restore the cranking if the problem is with one of them.
Mass Air Flow (MAF) sensor
Fuel bowl heater (if your model year has one)
Background info - The fan clutch is wired with the transmission range indicator. If the fan clutch is shorted, which can happen a lot, it takes out the range sensor so the PCM doesn't know what gear it is in, therefore does not engage starter.
Also - The forward-most PCM connector (called the C1381b connector) contains the transmission solenoids, speed sensors, range sensor and TFT sensor wiring. Maybe a short in that cable/wiring.
