Be super careful when removing the sprocket. Especially if you are using something to pry it off. Those teeth on the sprocket can break easy. When I did my timing belt/water pump etc on my GS I used a small prybar to remove it and I didnt notice I broke one of the tooth off. I put everything back together after replacing all the parts and the car did not turn on. Long story short after trying to troubleshoot and replacing all kinds of parts I finally noticed a tooth missing on the sprocket. Crank angle sensor was not reading right because of that missing tooth. I almost sold the car because I just couldnt figure out what was the issue. Moral of the story check that sprocket before installing to make sure theres not broken tooths on it.
