SOURCE: 1997 Blazer dash displays ABS light, Air Bag...sometimes battery light.

I think your BCM which is the body control module has failed, have a self test run on it to see if it will give any codes, if it won't test then it is the problem.

Disconnect the battery and reconnect.
This should clear the computer memory.
This may cure the problem.
Suspect extreme cold primary cause in transmission?
Good Luck !

SOURCE: Engine immobilizer system problem

you really need the dealer for this one. car is too new and should be under warrenty. This should not of happen. Most likely you have a computer issue with codes stored that will direct the technician in fixing this.

SOURCE: P0320 & P1391 OBD codes displayed.

P 0320 = No Crank Reference Signal to PCM. No Crank (shaft position) reference signal detected during engine cranking (starting).
P 1391 =Intermittent Loss of either Camshaft Position Sensor or Crankshaft Position Sensor.
Hav you attemtped the "3-Key-Ons" method to see these codes on your digital Odometer (assuming you have one) Turn the Key from Off to On (not start) three (3) times. On the third (3rd) time leave the Key in the "On" position (not start). Look at your Dogotal Odometer (if so equipped). The Codes, one at a time should appear. The Last Code will be "P donE".
If te engine is performing without problems: disconnect the negative side of the Battery and wait at least 5 to 30 minutes. Reconnect the Battery. Re-preform the 3-Key-On's and see if and Codes are now showing.
If you start having Start or Running problems becoming more and more frequent: consider replacing the Crankshaft Position Sensor. If this sensor "fails" you may not get any fire to anything, as this is the signal that is necessary for the PCM to initiate the Firing Sequence. The PCM will not send a signal to even the Ignition Coil to begin.
