Have him check the condition of the flex plate between the engine and transmission. This plate can crack at the bolt holes and create a situation where it bangs around. The starter engages the edge of the flex plate in order to turn the engine over. In addition, there are notches around the edge of the flex plate that are "sensed" by the Crankshaft Position Sensor. The CPS provides the position information needed by the onboard computer for triggering the correct timing to fire the spark.

And, if he missed the original source of the knocking (the flex plate if it proves to be bad) you might want to hit him up for some consideration on what he charged you for some potentially unnecessary work. The cracking of these plates are a fairly common issue on the older cars.

 

If this mechanic is finished with the car and you still don't understand what is wrong, then you need a new mechanic. If you are in the middle of repairs with a reputable shop, they should finish the work and provide you with the parts they have replaced for you. Have those parts checked by another reputable shop if you have any reason to believe you have been bilked.
