Re: [doc] Buzzing from engine

Hi Chris

The FV is not SUPPOSED to fire up on ignition but does so on may cars. It
has recently stopped doing this on mine and has made me notice the
accumulator is shot.

Stian, it should not run continuously with ignition on before you start -
it may run for a second or so. If it does not turn off, your RPM relay may
well be bad

> Today I went out in the garage for the obligatory once-a-week start and
warm-up of my DeLorean. It is stored during the winter time. At the same
time I wanted to check the door lights etc. so I didn't start the car, but
turned the key to "position 2", when I suddenly heard a loud buzz coming
from the engine compartment.

Its the frequency valve (FV) which is on the RH rocker cover ( opposite side
to the cold start ). When you turn the key to position 2 the RPM relay
powers up the fuel pump ( and FV) and primes the fuel system for starting.
