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.
