I had problems with my 2006 E350 5.4 l. It started dieing while driving! No reason 50,60,70 mph everything shut down, after rolling to a stop it gave the check engine light and the wrench. I could then Start the engine if nothing happened this repeated every 20 miles or so seeming to mainly chose inconvenient spots like uphill. CHECKED CODE AFTER 6 SHUTDOWNS. P0460 fuel level P061B Internal Control module It had no symptoms driving in town. Started up and idled flawlessly 2x when it shut down, it wouldn't start, but pumping the gas peddle 2x. And it started flawlessly Changed fuel pump, and fuel filter 30 miles later, same critical engine failure Got it finally to the repair shop and a bright young guy did a code check 1) all 8 injectors were giving error codes 2) Forced engine shutdown (Because of the cause of the problem. Other people may not have these exact symptoms but other weird codes, something else, that defies logic.) So it's ford's fault! They placed the wiring loom against a fiberglass wrapped ERG tube, INCLUDING the aluminum tape wraping.(I Think its an ERG tube) Remember those washboard roads/bumps, the constant rubbing finally ate through the wire bundled insulation and the insulation around those important wires. So depending on which wires are touching, the code will change. So you can't believe any of the codes as they may change as mine did. The worn spot CAN NOT be observed without the loom out of position and looking at the bottom edge (drivers side) Here is a picture of the shorting cable. It's removed so you can see it. If you looked at it before it was removed, you could not see anything as it was facing down. I hope this saves people thousands of dollars of analysis, and repair attempts. Ugly business but easily patched Hidden, must remove loom to see underneath
