Does anybody know if this car is equipped with the emergency "power switch" to the fuel pump? I have checked all the fuses and the relays and they all are fine. The positive wire on the pump doesn't get any power. Any suggestions will be greatly appreciated. Spent a lot of hours searching for the electrical diagram for this car and so far no luck. Thanks everybody for any info.

There is no shut off switch for the fuel pump that is for fords only, there is however 2 fuses and two relays that run the system please check the wiring diagrams below to see how the system works and which fuses and relay to check. Check out the images (Below). Please let us know what you find.

No clicking or any other sounds from the pump. I tested the pump. It works.
