Clicking noise
1991 year. When ignition is turned on (engine not started) I hear a consistent clicking noise from the engine compartment. Stops when vehicle started or ignition turned off. Thoughts from anyone? Thanks.

Re: Clicking noise
Air pump for the secondary fuel injectors?
Is it coming from under the passenger side headlight?

Re: Clicking noise
using a stethoscope sound is heard most near brake lines at the front wheels.

Secondary vacuum pump, underneath the PS headlight near the coolant tank. It should only run for a few seconds on initially turning on the key, then shut off and run a few sec. a short while later. If yours is running continuously you have a vacuum leak you have to find.
