SOURCE: 2004 Chrsyler Pacifica Won't Start

2 possible problem come to mind:

  • Bad ignition switch; faulty switch will occasionally make contact but not every time
  • Bad starter; less likely but possible; a bad starter will function when it's cold but when it heats up, takes much more power to make it work
I hope this helps with your problem and wish you the best of luck. Take care!

SOURCE: on our 2006 Pacifica, the cooling fans will start

The fans are controlled by a temperature sensor that activates a relay. Could be either. Since it is winter, you could try narrowing it down by unplugging the sensor. Then if it still comes on, it has to be the relay. It is does not come on, it has to be the sensor that is shorting.

What does the front control module look like?


Lightening that close probably fried everything. ECM,BCM,injectors,coils,ignition control module and more. I did an 05 grand prix that was welded on the exhaust. They hooked the ground to the on the body instead of the exhaust and fried everything in the car. The only way to check is to take the modules apart and look for burnt PC boards. Hand held computers wont read them, because they are burnt.

How to replace the ECM on a 2005 crysler pacifica


see the procedure and fix it. God bless you
    • 1 Open the engine compartment to access the battery. Disconnect the battery with a socket wrench.
    • 2 Locate the ECM either in the engine compartment or under one of the front seats in the vehicle. The ECM is a silver, rectangular module. Consult your owner's manual or appropriate car dealership for the location of the ECM if you don't know
    • 3 Disconnect the electrical supply by lifting the locking tab and pulling away from the computer. This will isolate the electrical power.
    • 4 Unbolt the screws holding the ECM in place with a socket wrench. Pull the old ECM out and replace it with the new one.
    • 5 Bolt the ECM in place with the socket wrench. Ensure the bolts are tight.
    • 6 Plug in the electrical wires to the ECM. The wiring harness will lock in once it is pushed in far enough.
    • 7 Connect the battery cables to the battery. Tighten the cables with a socket wrench.
    • 8 Start the vehicle and allow it to idle for five minutes. If there are still conflicting codes, the "Check Engine" light will come on.

2004 PACIFICA WONT START SERVICE IMMOBILIZER LIGHT ON VEHICLE WILL NOT DO ANYTHING


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.
