No that isn't normal, as it tends to sound like you have a fuel pressure leak, or the fuel pump relay is wonky.
I know most cars prime the fuel system when the key is turned to on, but the pump normally shuts off after a few seconds. When I turn the key to the on position I can hear the fuel pump running, but it does not shut off till I start the car. Is this normal with CIS? (This is my first car with CIS so I dont know what to expect from it.)
Ah, this is the post I was thinking about while replying to your other post today... Yes, take a look on your manifold for an O2 sensor (bearing in mind that I'm operating off of knowledge based on American-destined cars only...). At least your frequency valve is buzzing... Mine stopped working a few months ago when I was preparing to move my car back home but it turned out to be a combination of the Lambda relay, as well as the fuel-pump relay.
