Hi Scotty, while driving my '01 Ford Expedition 4.6L V8 (151k miles) at 55 mph, my instrument panel blinked, I saw the RPMs & Speedometer showing 0, and the Odometer had dashes (-). I then realized I had no power because the engine had died and I began working my way over to the shoulder with no power steering, brakes etc. Once stopped, the battery was turning the engine over very well yet I could not get the engine to restart (at this point I saw the odometer was showing the correct mileage). I had it towed. At the shop (about 3 hours later), the mechanic could not find any codes and the car started. They ran the car in idle on the lift for a while until it quit again. They checked and could not get any fuel pressure and are suggesting I replace the fuel pump that is only 3.5 years old. This diagnosis doesn't seem quite right considering what I saw with the instrument panel. Could the panel, or a computer, or electrical short, or regulator have caused the loss of fuel pressure and firing in the engine? What else should we consider checking before replacing the fuel pump? FYI, I replaced the battery about 3 weeks ago. Thanks

yes, sounds logical

update: mechanics checked the fuel regulator (good) then voltage going to fuel pump and decided to swap relays for the pcm and wipers. Car started and has been running a while with no issues, so they now think its the pcm relay and not fuel pump. Does this sound more consistent with the initial symptoms? Thx
