This PI was superseded to update Recommendation/Instructions. Please disregard PIC4110A.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
A customer might encounter a NO start or extended crank condition intermittently when attempting to start the vehicle. This condition can be caused by a lack of fuel pressure.
Recommendation/Instructions:
Before deep diving into the diagnostics, please check for a possible loose terminal at the Underhood Bussed Electrical Center (UBEC) for the fuel pump power supply. TAC has received reports that the terminal for circuit 120 (Gry) has been loose at the UBEC. If the terminal is backed out of the connector, replace the connector (the terminal lock is damaged and the terminal will not lock in place).
Inspect the corresponding male terminal on the UBEC. If there is a bent pin it is easy to straighten, using a business card (as a straight edge) and using needle nose pliers, straighten the pin. Then use the business card again to check pin alignment. All the pins should now be aligned together. If you find the male terminal "twisted" then replace the UBEC.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
