[DML] Re: Frequency Valve not working.

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

If the frequency valve is not buzzing you check all the simple stuff
first like plug connections, grounds, etc. If that doesn't get it to
buzz the next step is to see if the Lambda ECU is getting power. If
there is no power it usually will turn out that Lambda relay is bad.
Even if you hear it click the contacts inside may be bad. Another
possablity is the RPM relay. Not only does it control the fuel pump,
it powers the Lambda too. There are other things that can prevent the
Lambda from working so a wiring diagrhram is very useful along with
some test equipment. When the Lambda isn't running the motor will idle
badly and run like cr-p.
