Bought the car not running discovered it was in the timing. The idler pulley was broke and the gears were off point. Question is, (1) Will it be okay if I just changed the pulley an have someone put it? (2) Back in time an what's the procedure of setting the gears back in time?

Hi and thanks for using 2CarPros.

The 2.0L DOHC engines are interference engine. With that in mind, there is a good chance internal damage has occurred. You can take the engine apart to confirm damage or replace the belt and then check engine compression. Here are the directions for replacing the belt. All attached pictures correlate with these directions.
