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 !

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.

I have a very small oil leak and my oil light comes on while idle I have a 05 Chrysler Pacifica touring 6 cl 3.5 where should I start

You might take a look at this article.
On a fully warmed up engine at idle, the oil pressure, 5psi min. So says my database.
You might be able to use an analog gage in place of the oil pressure sending unit, to double check oil pressure.

Check engine light flashing won't start

for now you must try to charge the old battery see the diagram attached.
2) Run the scanner/computer for easy diagnostic and fix it. You have some problem with PCM or BCM+sensor, ignition coil,distributor etc see the diagram attached.

2006 pacifica stalled out while driving. Now it won't even try to start. Check engine light came on.

A good read. That car is only 6 years old... I would say bye bye to Chrysler forever.

OK, if the vehicle won't start and the service immobilizer light is on then I would definitely take it to the dealer in order to have the key programmed to the computer, again.

Did the battery go dead lately? Is there a code associated with it not starting, as in the immobilizer function lamp?

or the key is not programmed to the ecm?

P0633 Immobilizer Key Not Programmed ECM/PCM
This is just a possibility to look into.

2004 pacifica service immobilizer message on. Car will not start using both sets of keys. Please help!!!

There is a little black plug under the steering wheel near the center console. That little plug is the immobilizer I believe. If it is loose or missing, the car will not do anything, hopefully yours is laying in the floorboard somewhere!

Check Engine Light

If the light isn't flashing, it is safe to drive. If it is flashing, then catalytic converter damage can result. Have a parts store check the codes for you and come back and post the code.
