Default 10-PCM - No Comm

Started the car today and the car just stops and stalls in my driveway.
messages on the display -
Reduce Engine Power
Service Traction System
Service Vehicle Soon
Service ABS
Ran the codes and got a code 10-PCM - No Comm
Does this mean my computer is screwed up?
I'm stuck with the car in my dirveway, car cranks and won't start.
Any help is appreciated, Any Long Islanders around that can help?
Thanks
Bruce

If the BCM and PCM cannot communicate you are going no where.

Check the battery and battery cables to make certain cables are clean and tight and that the battery voltage with the Neg battery cable disconnected is greater than 12.5 volts. Also start checking grounds. Here is a link to a Bill Curlee thread about the grounds:
