Where is the starter on my 1994 buick park avenue??

Access to the start on that car is achieved by going under it. Once there you will see a cross bar going under the engine. The Start is right up against the bar on the backside of it.

Two 15mm bolts hold the start in place, but you will need to use a swivel socket to get on the front one, otherwise the bar will prevent its removal.

Good Luck, and thanks for using FixYa.
