Hello, I am considering buying a non running RX8, from the pictures it seems to be in good condition so I am wondering if anyone has any idea about what the issue is, at the moment I am assuming the car is turning over and is not seized. The pictures of the car have a garage sign in the background but with the description of the add it sounds like the garage has been throwing parts at it hoping to hit the problem area and the guy has ran out of money to spend on it.

If someone could give me some idea as to what the issue(s) could be before I consider buying it I would appreciate it, with the condition of the car I would offer the guy 500£ and if I couldn't get it going I would just break the car for parts to make my money back so I don't mind either way.

Thanks
Michael

"Mazda RX8 £550"

"Has just had all new pipes fitted by Mazda worth over £600"
"New catalytic converter worth £200"
"All new plugs and coils worth over £200"

"Won't start and I don't have time or money to work on it anymore."

So after reading through the forum I found a symptoms and causes thread with a few reasons for an RX8 not starting on it.

https://www.rx8club.com/new-member-f...causes-249529/
"cranks but doesn't fire"
"flooded"
"ignition failure"
"fuel pump failure"
"e-shaft sensor fouled"
"fuel pump failure"
"engine compression loss"
"starter failure"
"fuel system leak"

Ask the seller if the engine cranks. And then start from there.

I would compression test it so you can determine whether or not the engine is toast.
