Ford vehicle lost power and stopped running with full tank of fuel. Would not restart, had towed to repair shop. Replaced fuel pump for $606.99. Drove about a mile and same thing happened again. Found that the fuel inertia shut off switch needed re-setting. Bought a fuel pump I didn't need. This has happened multiple times this year again. Ford dealer said I needed a fuel pump. (35,000 miles) again, no way. The replacement part (inertia switch) moves the switch from passenger floor area to side kick panel. The design change shows design flaw. Ford should replace for no cost. Very dangerous when engine dies.

Approximately eight months ago my vehicle stalled and would not restart. It was towed to a dealer and approximately $300 later I was told that the inertia switch had failed and had been replaced. Two days ago the same symptoms appeared and the vehicle was towed to the dealer again. I did some internet searching and found info and a youtube video that explained where to find the switch and how to reset it. Went to the dealer and attempted the reset in their parking lot before they completed any costly repairs. Vehicle started and has worked fine since. Possibility of stalling in traffic is a concern but I'll take my chances!! noteworthy that a close friend who owns an older model Mazda pickup recently had the exact same problem with the inertia switch replaced.

I was pulling into sherry's MINImart in doe run, mo when I realized that my truck was not slowing down as expected, even though I had my foot on the brake. I had little time to react as I was bearing down on the building. I put my other foot on the brake but the truck continued to move forward, even spinning the tires trying to overcome the brakes. I jumped the curb and hit the building at a very low speed. At this time I managed to pop it out of gear. I did not go through the wall, but pushed it in about a foot. My airbags did not deploy. Most of the damage was to the wall and the interior of the building. There was little damage to my truck other than a few scratches on the bumper. Luckily no one was walking in front of me or near the inside of the building. This was the only time this has occurred in the 50,000 miles that I have owned this truck and it has not happened in the days following. I took my truck to my Ford dealer the next morning and they claim they could find nothing wrong. They could find no fault codes in the computer and confirmed that there was no damage other than the scratches on the bumper. They did imply that I was hitting the accelerator pedal with the side of my foot while braking. I strongly disagree with their implication and have witnesses who saw my efforts to stop the truck.

Inertia switch in 2006 Ford Ranger causes truck to stall randomly. Switch is located on passenger-side in compartment by the foot. This random stalling is especially dangerous while in three lane traffic, railroad crossings, intersections, bridges, etc.. this switch is designed to cut electric to fuel pump in crash but most often fails during normal driving operation. This is not a unique complaint to 2006, but by other years reported on the internet. This problem has existed for many years and is probably responsible for more deaths due to errant operation than it saved lives in a crash. Another example of what seems like a good idea gone bad.

I own a 2006 Ranger 3.0 auto. That has 35,300 mi. The fuel delivery inertia switch has kicked out under normal driving conditions twice. First time at 32,172 mi. And had to be towed to a dealer. The technician reset the switch and I had no problems until 35,100 mi. This time I was lucky enough to be in a parking lot, instead of out in moving traffic. When tis happens, the engine, of course, dies immediately. The switch cannot be reset while sitting in the driver's seat. The dealer will not replace as they cannot fail the switch during " their" road test.

I was in stop and go traffic in my 2006 Ford Ranger with approximately 3500 miles on it when engine sputtered and stopped as I tried to accelerate. The gas tank was near full and the truck would not restart after I coasted across a lane of moving traffic onto the median. Having experienced a similar problem in my 1986 Ranger, I called the dealer service center to ask where the fuel safety shut off switch was located. After being assured that the switch could not be the problem unless I had been in a collision or hit a very large pot-hole, I reset the switch and the truck started. The switches in these trucks apparently has a defect that has not been corrected for 20 years. The service people seem to be unaware of the issue and I suspect that many people have been sold fuel pumps and other related items that were not the problem. I am just glad it didn't happen at 65 mph.
