fuel pump switch

[tbird 1991]

Well I was cleaning out my trunk today when i saw on the driver side rear wheel wheel had a switch that said fuel pump shut off switch so me being curious i pressed it in and now i dont know how to reset it lol the button wont come back up i pushed it in and now it stays in instead of it staying up how it was. Does anybody know how to reset it it says to read the manual for the reset instructions but i dont have the manual its a 1991 thunderbird.thanks

My old cougar has the same switch. It is in case of a rear end collision, it is supposed to automatically shut off the fuel supply to the engine.

As far as I can remember it should be an on/off switch. Push for off/push for on like a GFI switch in your house. If it won't trip on, check with you local ford dealer's service department, they should be able to tell you over the phone how to reset it. You may also want to check the fuse panel, if their is a bad connection you may have blown the circuit.

If this still does not work, take the two power leads and join them together affectively bypassing the shut off.

hope this helps.

Are you saying the car won't run now? The button should stay in for the fuel pump to work. If you get into an accident the inertia switch shuts off the fuel pump. To reset it, you push in the button. This switch is there for your protection so don't ever bypass it if you are going to drive the car!

I simply suggested bypassing it to see if it is the switch or another problem causing it not to work.

These are simple switches and you should be able to get a simple replacement.

That's why I stated "if you are going to drive the car". It's one thing to test the switch and another thing to leave it bypassed, if in fact it is bad.
