I have tried jumping it off and I've had the control module changed out.

Hi,

When you say it won't start, do you mean the starter isn't working, or does the starter turn the engine but the engine doesn't start?

If the starter is working, take a look through this link and let me know if it helps:

If the starter isn't working, here is a link that explains how to check it:

These links are basic and straight forward. If possible, let me know exactly what is happening and if it happened all at once.

Take care,
Joe
