Will not run right

Hi,

Scott, what needs to be done in this case is the scan the CAN BUS system. The things you mentioned don't necessarily seem related (PS / Theft), so it make it very difficult to diagnose.

When you scan the CAN system, the scan tool reaches all computers / modules and identified where there is a fault. From that, a code will be retrieved to point us in the right direction.

Here is a video showing how it's done:

This is where I recommend starting. If you can, have this done and let me know what codes are retrieved. Also, feel free to let me know if you have other questions.

Take care,
Joe

Hi,

It is very possible it is related to the alternator. That makes sense. Do me a favor. Here is a link that explains how to check the alternator. All you need is a voltmeter or even a multi-meter. Do this and let me know the results.

If you find the alternator is not producing, here is a link that shows in general how one is replaced:

Here are the directions specific to your vehicle. The attached pics correlate with the directions. Just make sure the battery is disconnected before you start working on it.
