Does anyone know where to find the inertia switch I have been told behind the glove box under dash or behind engine on the bulkhead can't see it in either place on mine. I have no voltage at the fuel pump and have changed the relay and checked fuse the car cut out soon after hitting a large pothole which is why I suspect the switch.

Did you check the yellow connector in the steering column mentioned in the previous thread?
You need to remove the steering column cover to get to it - and then pull the yellow connector apart and look inside - it will look OK from the outside.

It does sound like a general power problem so I'd look at this first.

I presume when you hard wire up the fuel pump it is whirring away even if the engine doesn't start?

There's also a connector on the nearside rocker cover than can give issues too, but nowhere near as common as the yellow fatherless connector rolleyes

AFAIK I don't think TVR fitted an inertia switch to the S series.

I also suggest the yellow connector replace to prevent the inevitable future issues.

Did you say the pump was inop when directly connected to known good power and earth? If so sounds like pump to me?

Good hunting.
