Have you check all of the fuses?

Yes checked all fuses everything just stop working at once

If it runs with a shot of fuel or starting fluid you may have a bad fuel pump relay or a weak fuel pump, plugged fuel filter maybe.

Did pressure test on fuel pump, the check engine light doesn't come on either. Had a mechanic tell me the fuel pump was OK because that's what I thought it was. They did a scan on it and nothing shows up.

Did he tell you what the pressure was, it should be around 40 to 45 pounds. in some cases a weak pump won't show on a scan.

The door locks will be a fuse, master switch or a wiring issue.
