A mate of mine is rebuilding his RS500 prototype no.4 and he's having troubles with the fuel pump.

He drove the car in the garage last year and now it refuses to start at all.

Is their a inertia switch like on the Esc Cos and if so, where is it?

He does have a wiring diagram of a LHD 3door but is the RS500 the same as that?

Can anybody please help us???
