dont know if it has one or not BUT IF it does, it will be in the REAR inside fenderwell(pull the carpet back). It will be a reset button somewhere in that area. Usually doesnt activate unless you get hit from behind or back into something.
Pontiac does not use an inertia fuel cut off switch.
does a 1990 e250 have a fuel cut off switch
I called Pontiac there is no cfuel cut off switch.
there is not one
GM vehicles do not have a fuel shut off/inertia switch
is there a emergency switch that shuts the fuel pump down
Take out the fuel pump fuse and then start the car until it cuts off on its own. After it does cut off, the system is relieved of pressure.
the relay for my 1990 for the fuel pump is on the left hand side in the boot near the fuel cut of its on the wall behind the carpet
try going to www.autozone.com and enter your vehicle info and look for the inertia switch location.
Not unless you cut a hole in the floor.
I believe it is located under a panel on rear right of trunk.
Fuel cut occurs at about 12PSI.
