I checked fuse #34 with the an essential on and also it had actually power and was an excellent so that got rid of a faulty pcm relay and related wiring. The following step was to find the irradiate blue/orange cable in cavity #12 the the C270B connector. That is in the reduced right hand edge of the twelve cavity connector just listed below the connector that ns am backprobing in the picture above. When the ignition is turned on the analysis was close to zero volts and also after a couple of seconds it visited battery voltage. This told me the the pcm was making use of a ground to energize the fuel pump relay coil. With all of this trial and error I knew without a doubt the the fuel pump relay the is component of the inner fuse box was faulty.

Disconnect the battery an initial before remove the fuse block. Over there is a battery feed cable that also has to be disconnected ~ above the rear edge the the fuse box. That is located under a cover. I have pictures of that at the finish of this post. Over there is just one bolt that holds this fuse block in place.

In the rear.

The fuse block eliminated from the vehicle. You have the right to see the battery terminal post on the lower left edge.

*

I took the ago cover off of the fuse block and also started disassembling it.

*

The damages was even easier to see from the relay next of the board. I feel relatively confident the if this problem would have actually been captured soon enough, the solder joint could have been repaired or a new relay set up (if one can have to be located).

*

I plugged everything back in and also bolted the fuse block in place.

*

The cover because that the battery stud top top the fuse block.

*

I put every one of the covers ago on, clearing the codes and test drove the vehicle. This one is done.

This repair will certainly generally use to Ford and Lincoln full sized trucks and also suv’s in the same years//body style. Check diagrams and also component locators before jumping any kind of circuits, as I did.
