FCA hangs open and the CP3 just keeps pumping and pumping. Pretty soon, BOOM!

Just watch the injectors and oil level to make sure it didn't crack one and start a leak.

I had a dmax pump do the same thing on a dual CP3 kit. It completely came apart inside. I've heard a valve sticks and it tries to compress the high pressure fuel again, boom! Mine made a big mess everywhere. Had fuel from the rear door to the tailgate.
