I have a 2004 rx8 automatic transmission. Mazda replaced the motor about 30 thousand miles ago. The car will try to start but won't run. I've been told many different things, and I am just trying to get it running again. New spark plugs and fuel pump less than 10k miles ago. Was told the starter tested fine but I was also told that the starter can test fine but still be bad. New battery was put in today. Any help would be appreciated.

 

Read the "starting issues START HERE" sticky found at the top of the troubleshooting subforum, and then read the new and potential owners sticky found at the top of the new members forum. It details the basics of the renesis.

 

I'm not a new owner. I have had the car for two years. I know a lot about it but I am stumped.

 

Ok well you mention spark plugs. Have you tested the coils coils? Have you tested the compression? You mention fuel pump. Have you checked the fuel filter?
Are you getting any cels?
