RX8 runs on one rotor

I bought an 04 RX8 back in may, owner had replaced the stock renny with a used 30k one, back in November i replaced the tranny, made sure to buy a new clutch and flywheel, as well as bought a braided line for the clutch line, everything worked fine, in December i started experiencing hard cold starts, it would take a good 8-10 seconds to fire up, though when warmed up and hot it would fire up right away, anyways, a few days ago a couple buddies and I were going out to eat when all of a sudden it lost a lot of power, it soon turned off on me a few seconds later, after trying to start it back up, it didn't want to, it cranked but something was off, I got it towed home and a few hours later I got it to turn on and only 1 rotor was working, I had replaced the spark plug wires 1K ago, i bought new coils and spark plugs, put them in, and it seemed like it helped but still only 1 rotor would work, I checked for spark by using a tool that you connect to the wire end to the plug and lights up every time theres a spark, all 4 wires were getting spark, i deflooded it with all the plugs out and made sure to disconnect the fuel pump and coils, and turned it over in 5-8 second intervals making sure to wait 10 seconds after each, and making sure to wait a few minutes after a minute of deflooding. after that I got new plugs for the front rotor (I assumed I fouled them) and then cranked to confirm both rotors were turning. after, I put everything back together, and still the front rotor wont turn on, only the back one does, once again I took out the plugs and the front rotor plugs did get fuel, obviously they both did since the rear one turned on, I don't know what could be wrong. I was driving and out of no where it seemed like I lost a rotor. is offline

It happens. Sounds like an apex seal went out or something.

Check the compression. This will tell you all you need to know. Youíve done more then enough messing around with it. Sounds like itís a goner man.

I don't remember where my compression tester is, but just by the sound of the rotors cranking with the plugs out, I can tell the rear rotor has way more compression than the front one, the front one sounded too quiet compared to the rear one. Thanks! is offline
