Question

How to check code b1213 on my Mercury Mountaineer 4.0L? The engine won't over and the fuel pump not coming on.

Answer 1

The problems with the no start and fuel pump are not related to the code B1213.

The B1213 code means that you have an issue with the Passenger Seatbelt Buckle Pretensioner. If your car was in an accident, you must replace the seatbelt buckle, otherwise, check the seatbelt buckle for any damage and the seatbelt buckle wire connection.
