This is totally off topic but if you want to change the fuel filter can you hit this button while the truck is running to deplete the gas line pressure change the filter than press the button again to reset the pump back to flow.. Just wondering especially if this happened for arcuhtek. Thanks for any info

on the older fords they had an inertia switch. usually in the trunk on cars... and if the car was hit hard it would trigger the gas flow to stop... sometimes it would trip for no reason though and people would be stumped....it may have tripped by itself due to wires being messed... fords way of keeping a theif from stealing your truck... if they were to cut wires etc... just a thought...

I cannot say for certain what I did to cause the fuel pump to be temporarily shut off, or what did it....inertia sensor or not.
If I were "guessing" I would say that this MIGHT not have happened if I had also disconnected the positive battery cable. I have this feeling that whatever triggered it, was due to the fact that the fuse box must somehow have a direct link to the positive battery cable. I know for certain the fuse box has an independent ground (I disconnected it). So me thinks that messing with the ground at the fuse box, while the fuse box was still live...may have triggered something.
On another guess....
When I disconnected the fuse box ground, and the five harnesses from the fuse box...I then had to carefully twist and turn the fuse box, out of my way (to get a good workig position for my drill) and if that inertia sensor is in that fuse box...and IF it can sense when it is turned upside down or at a sever angle....then me moving the fuse box out of the way, very likely triggered the inertia sensor, which shut the fuel pump off.

It was from being moved. I saw the guys on the other site suggested the same thing. Glad you got it worked out.
