1998 f-150 cranks but won't start

My 4.2L died all of a sudden, it cranks but won't start. Checked the harness side to coil packs, pos. signal but no neg. Tried a code reader keeps coming back link error. Does this mean PCM is fried?

You lost power to the PCM, most likely. Check related fuses, see owner's manual.

Get the meter out and check for power to the PCM circuits.
