I am having problems with my 2004 pacifica. My ignition switch fuse blew and car would not start. Once I replaced it, the car still would not start and now just says "system immobilizer" every time I try to start the car.

Basically, the vehicle thinks it is being stolen so it is not allowing you to start the engine.

Here is a guide that will help with disabling it:

If this does not work, then we could have another issue, so we need to check for codes and see what is there.

Here is a guide that will help with doing this:

Once we know what the codes are we will have a better idea but let's start with this info and we can go from there.

Thanks
