- Customer Satisfaction Program. Certain vehicles may have an incomplete or missing braze between the harness bulkhead support bracket and the fuel rail assembly. If the braze is incomplete the support bracket may detach from the fuel rail assembly over time. Wiring may sever and compromise the function of the fuel pump and/or the 4 passenger side injectors. If the function of the fuel pump and/or injectors is compromised, the Check Engine Light will come on, and you could experience reduced engine power. Loss of propulsion is possible, and there is a remote chance of fire if there is a fuel leak. Replace fuel rail assembly.
