For the one who has not heard of a fuel cut off switch.
Ford and GM have different ways of doing things.. In part I suspect due to the exploding Pintos of several years ago, FORD has a fuel cut off switch, This switch shuts off the in-tank fuel pump in the event of an accident or rollover in order to reduce the odds of a fire.
Simply hitting a pot hole can trip the switch,,You do not need to have an accident.
Thus, if you drive a FORD. it pays to know where the switch is
Wife used to drive a Mercury Tracer (Ford Escort re-labled) and on two occasions when I had to drive it due to my car being in the shop I hit a pot hole (Same dang pot hole) and took out that switch.
Thankfully. I knew where to find it.
Home is where I park it!
