You can simply unplug and remove your CAS. (10mm bolt) - And then line-up the dimple on the CAS gear with the notch on the CAS shaft.


Remove the top lid of the CAS (two philips head screws). Make two reference marks that line-up inside of the CAS so that you can keep the gear dimple and shaft notch lined-up below. (Keep in mind, the CAS is still out of the front cover. I'm only using the pictures as a sort of reference.)


Now, line-up the YELLOW mark on the main pulley with the needle that sticks out of the front cover. (Yellow mark... Not the red mark as shown in the picture.)


"Stab" or reinstall the CAS making sure that your reference marks stay lined-up. Keeping the reference marks lined-up is important... It ensures that the gear dimple and shaft notch stay aligned during reinstallation. You can now tighten the 10mm bolt to keep the CAS in place. Reinstall the top cover or lid of the CAS with the two philips head screws.


You may also be having a secondary fuel injector issue. Strap/secure the injectors to the fuel rails. Unbolt and remove the fuel rails. (There's an illustration of this in the 89' FSM. "Fuel and Emission Control Systems" F1-56) - Obviously you do not remove the injectors or any of the fuel lines. Be sure to set some rags or something under the injector's fuel outlet nozzle, to absorb fuel in case they are stuck open. Jumper the yellow fuel pump test connector at the passenger side strut tower, near the AFM. Turn the key to "ON"... Not to "START". You'll hear the fuel pump running... Now go check the injectors to see if they are spewing/leaking.

If you do not have a Factory Service Manual, here is a link to the 1989 FSM "Fuel and Emission Control Systems": http://foxed.ca/rx7manual/manuals/19..._non_turbo.pdf
