There are two sensors near the crank pulley (The pulley that propel the rest), the top right side of the pulley. It looks like two sensors. Well the lower of the two snaped somehow, now car will not start. I have pic, but to big to post. Can someone help me out.

 

very important sensors. they determine your timing. w/ no signal you car will not start.

 

How to replace and at what cost please i need to know.

 

Due to the wording of your question and age, best to find a RX-7 shop and let them do it.

Ask Mazda parts for new price, or a recycle place for used price. Have you a Mazda FD RX-7 shop maintenance manual. If not, get it ASAP and learn it.

 

Chuck, you might not remember me, but I have talked you before. I am a member of the Houston Rx-7 club. Marcus is the guy I go to if I have any problems, but since a took out and reinstalled my motor myself, i would like to think I know how to change out the sensor. Now if you think I am incapable of changing this sensor out due to my age, then thats your opinion. But if anyone would like to actually help me rather then insult a fellow rx-7 owner please do. thanks

 

what is actualy broken? just the conections?
