So i was driving my truck a couple months ago and it just randomly shut off.I was able to push the inertia switch and it started and I made my way home as usual.Well, I was on my way to work last monday(everything happens on a monday) and the engine cut off in houston traffic(even worse). I managed to muscle the steering wheel to the right side of the free lane. My truck would not start back up and threw a p0231 code, or the "fuel pump secondary circuit low" code. Had it towed back to my apartment. I read on here and saw it might have been the inertia switch.Replaced the inertia switch and a week later it died on me again! So reading some other ford forums of this happening, I found that it might be the "non-serviceable" fuel relay on the inside fuel panel. took the fuse panel apart and lord and behold, its burnt. Bought a new one and awaiting the new fuse box. Should be here Monday. I would replace it myself but the way the circuit boards are made, theres no way to get the underside.
