Inertia switch
3 Answers
There is no inertia switch as such, that is only found on Fords. GM uses the ECU to disable fuel pump in event of a crash. The fuel pump relay will be in the under hood fuse/relay box. If you're not getting power to fuel pump make sure anti theft or immobilizer isn't active.
