The 1993 Mazda the inertia?æswitch can be found on the firewall in the engine compartment. The inertia switch will be on the passenger side of the firewall.

A 1993 Mazda MX-3 does not have an inertia switch. If anything is wrong with what would normally be the inertia switch, the fuel pump may be faulty.

What causes my Mazda mx3 to turn off while driving down the road.
The neutral safety switch, release switch, or brake switch is bad.
Mazda has a recall on their seatbelts for some models for this reason. ask a Mazda dealer if your model has the seatbelt recall. I believe the 92 mx3 has a recall for the auto seatbelts, but i am not sure about 93. Look into it though and they might fix it for free!
