I have searched and not finding location of the 996 Fuel Inertia switch?  Model year 2000 996 convertible if it matters.  Thanks!

As I have never heard of such a thing, what exactly are you trying to do?

Car was in an accident driver side front and now will not start.  Fault code 1397 camshaft position sensor is active, checked and have 5v and ground at sensor connector so replaced sensor, reset code, still no start and 1397 is active again.  I do not hear fuel pump when keyed on, I know some cars have inertia switch to shut off electric fuel pump when in accident hoping this has opened fuel pump circuit.  I read older model Porsche this fuel pump cutoff is performed by engine computer relay, but not finding info on 996.  During internet search Autozone sells a “Duralast Fuel Pump Inertia Switch SW1771” for model 996.

 

I am also hoping fault 1397 resets itself after engine start - this is still concern.

 

BTW, car was wrecked 7 years ago and not tried to start since.

And, I think your Fault 1397 is a separate issue.

That’s how I thought the system worked, without a separate switch or control system.

 

If the air bags deployed, that needs to be corrected before the DME will allow the pump to run.

 

P1397 code is for an “implausible signal” from the sensor, which may be a wiring issue.

Thanks JFP in PA, that helps a lot.  Air bags did not deploy.  Back to searching for the P1397 issue.  I might post separate question on this FC
