HELP! JB4 installed and now car won't turn over.

Just installed the JB4. Got in my car to turn it over and it won't turn over. When I press the start button everything lights up it says to depress the clutch to start but when I do that it does not start.

I'd uninstall the jb4 and see if it turns over then. Maybe you installed something incorrectly? (Everyone is capable of making a mistake) If the car turns over after uninstalling I'd reinstall carefully and see if that works.

Good luck!

Were you trying to install the OBDII interface also? If so, when you removed the under panel near the footwell you might have disconnected the clutch sensor. It looks like a small flat piece of plastic, just snap it back in to place.

Looks like this:

Hope this helps..

We have a winner! Thanks man. Contacted BMS support and they had the same suggestion. That was it. For others reference: here is what I unhooked.
