I'd suggest entering a complaint into the NHTSA Complaint Database (see
). I took a look at the
complaints related to late model Rangers and inertia switches and found the
Model Number of Inertia
Year Switch Complaints
2005 2 complaint, no injuries, none with multiple occurrences
2004 1 complaint, no injuries, 2 occurrences caused by passengers
2003 1 complaint, no injuries, 5 occurrences, caused by passengers
2002 0 complaints
2001 0 complaints
4 complaints for 5 years worth of production does not seem to indicate a
major problem. I did think it was interesting that 2 of the 4 complaints
specifically mentioned that passenger's feet caused the switch to turn off
the fuel pump. One of these claimed that he switch connector was dislodged
by the passenger's foot (5 times!). The other was less clear. Is the switch
really that easy to hit with feet? The owner's Guide for a 2005 Ranger shows
the switch mounted on the side of the truck above the carpet near the glove
compartment. I can't imagine the passenger's feet hitting it in that
location. Is it possible you have something heavy in the glove box that is
banging around in the area creating a sharp vibration?
There were actually more complaints related to the rpm limiter built into
the PCM, than about the inertia switch. You have to wonder about the sanity
of people driving Rangers faster than 85 or 90 mph. Especially when they
complain to the Government that the vehicles won't go fast enough. I
especially love the people who complained that since the speedometer was
marked to 125, the truck should be able to go that fast as well.
