I contacted my local Mazda dealer and they said they could not diagnose the car and for me to take it to an auto electrician.
It has now been towed to my mechanic who is working with the auto electrician to diagnose the car.
This is my biggest frustration and disappointment with owning an RX8 being, no one seems to know anything about them (in my local area anyway) and fobs it off or diagnosing every small problem to needing a new engine. I live near to Brisbane which is a capital city mind you.
It was Mazda (two different dealers) who told me I needed a new engine when the car was just flooded.
Thank you so much, I know you are giving your best advice and if my Mazda dealers had a better knowledge it makes perfect sense and was my first point of contact. When they cant help I am abandoned and have to try forums (how I self diagnosed the engine flooding) and thought it was worth a shot again this time.
I will let you know the outcome, unfortunately the long term outcome will be probably be, I will trade the car on something I can get fixed a lot easier. Thing is what the heck can I buy that measures up to the look and power of the 8.
