I have a 2004 nissan 350z with a few upgrades. Recently I had a ACT 6 puck clutch and act flywheel installed. Started up fine, as i drove away i stalled it(wasnt ready for the 6 puck). Stalled it a few more times leaving and about the 4th time, the car wouldnt start. It would turn over, but wouldnt start. After about 6 seconds it started. This problem hasnt gone away. Any suggestions???????

 

ECU knows Engine (CrankShaft) position from the reluctor ring on the flywheel....

Posible it was improperly installed or damaged. Take it back to the installer.

Also, the peddle needs to be adjusted after installing a new clutch.

Also, a 6 puck disc is way to much clutch for a stock motor, better off with an organic Disc.
