Customer Question

my mazda rx8 wont spark plug wont fire when cranking

It sounds like your eccentric shaft position sensor has failed, this is what tells the computer when to fire the coils. To test the sensor use a voltmeter to montor ac voltage while cranking, if it does not put out voltage relace. Let me know if you have questions, thanks

Expert:  Dan replied 7 years ago.

I attatched a picture with instructions on the last post but you probably read it after I did that so check it again and let me know if you have questions, thanks.

This just all of a sudden started happening? Is there a theft/security light on the dash that is on or blinking? Thanks

Expert:  Dan replied 7 years ago.
I'll opt-out and let someone who is more familiar with this security system help. Someone will respond autmatically if they can help. DO not reply otherwise the question will be locked to me, thanks.
Customer: replied 7 years ago.
hey dan i did not get any reply from anybody
Expert:  Dan replied 7 years ago.
Then so far there no one that feels confident in answering the question. Different experts are online at different times so it might take a day or two until someone is able to help you. But everytime you reply to me the question is locked to me again. So not not reply and someone will help you as soon as the right person sees the question. Thanks

Expert:  Mazda Ed replied 7 years ago.

Does the key light blink when the key is turned to run?

How many keys do you have?
