The K-jetronic or CIS injectors that come origonal on your car don't make any clicking noise at all. They spray fuel continuosly and silently like a garden hose set to cone spray pattern and sometimes one might make a little squeak like sound.
Some old Bosch EFI injectors make a light ticking as they open and close. It's most noticable at idle speed if a quiet muffler is still on the car.
Newer EFI injectors seem pretty silent to me.
If you post a recording or video with sound maybe someone can make some educated guesses.
If your mechanic has any experience on these cars and he can't figure it out then the rest of us can only guess.
