If yes then suspect the battery and or contacts to battery.
But if no change then I would say yes the starter is prob bad.
Been there, done that twice on Daughters SER. My 1.6 is still trucking.
Keep your paper work. If you get the choice get a long nose starter, there are two styles, don't remember which make is long nose sorry, but it obvious if you compare them. Nose goes round end of the pinion gear.

Please search, there is a "how to" written by me that was then improved on by someone else.

The starter is under the intake and is a bxxxx to get at.
If you find the starter on your 1.6 under Air filter box over the transmission, it is in the same place BUT on the other side of the flywheel/ring gear, so you can't see it.

Good Luck.....
