My info is somewhat limited on your model here but I had seen no one else has responded and would like to see if I can help here.If at any time you feel that I cannot help with this please let me know.

If the damaged area that was repaired was not inspected for any damaged wiring or connections this needs done.If a damaged wiring harness or electrical connection is found this will need repaired to correct this fault here.If this is or was already checked and found o.k. let me know so we can continue.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.Thanks Pete.

Were all fuses checked in all fuse panels at all?

All the fuses and relays are all good and power

I heard that this model has a shutdown relay in the brake system but I haven't found one yet
Expert:  Pete replied 1 year ago.

O.k.,unfortunately my info doesn't show anything on a shut down relay on this model here or its location.It is possible if this is equipped with this shut down relay that it is faulty needing replaced and I know on some models the fault codes need cleared out/erased after an accident like this before the vehicle will restart so if this hasn't been checked into this should be done as well.

The only other thing I can think of if all wiring is good is the electronic ignition switch itself needing replaced.I have seen some of those fail before needing replaced.

Thanks Pete
