I just bought a 2004 rx8 and a guy that towed the vehicle for me tried to jump start it and confused negative and positive cables. The main 120A fuse blew up, but after replacing it I still cannot crank the car. It makes me think that security does not recognize the keys anymore. Here is the questoin. Where is the LUCAS immobiliser located? I need to get a 10 digits serial number.

Thanks

 

No the system is different to the old stuff, you may find more than one fuse has blow, check all the fuses in the Engine fuse box and all the fuses inside the vehicle . Let me know how you get on . I have had this fault before and it took me a while to find about 7 different faults on the vehicle including a repeated fuse blow that one was very fun to find NOT. Il give you more help later but first inspect all the fuses and replace any blown ones with new exact rated fuses.
