Hello my name is ***** ***** thank you for your question.

The U1001 code that is normally due to a control unit failure. This will require what they call a CAN diagnostic check done to determine which control unit has failed that would need to be replaced. The CAN system test will do a system call on all control units and show which one is not responding so that control unit can be properly checked and replaced as needed.

So you will need a advanced level scanner that can do this to isolate the control unit that has failed so it could be replaced.

But what ever control unit has failed, I am sure is effecting the vehicle from starting. The most common is the Ecm. They do tend to fail on these cars.
