Not Ranked
The 9x03 starters are the correct ones for the 0.75" mounting depth. The 9x04 ones are for those with 3/8" mounting depth.
First, make sure the mounting plate is sitting flush on the engine plate. I've heard that sometimes it gets installed just a bit offset when the starter mounting plate catches an edge on the engine plate.
Also, along the same lines, some starters have a slightly smaller hole in the motor plate. The "automatic" and "manual" labels for the transmission type should be ignored. Count the ring gear teeth, measure the flywheel depth, measure the mounting hole diameter (to the .01") and make sure you have the right part.
If it is flush, remove the starter from the car, clamp it (securely) in your bench vise, and bench test it with 12v. If the starter gear doesn't come out and spin, you have a faulty starter.
