2005 dodge 3500 puck problem

[Clayw2012]

I took my puck off and put a smarty jr on then returned my truck to stock a few days later. I tried to put my extreme power puck back on and my truck won't fire. If I unpulg
It and plug the stock sensors back in it fires and drives fine. Any suggestions

Sounds like an installation issue.
The test we always advise in a situation like this is to unplug the harness coming from the adjustment knob to the Puck itself. When that is disconnected, the tool has no influence and becomes nothing more that a jumper harness. If the vehicle will not start when the adjuster knob is unplugged, something is not connected correctly or the harness is damaged.
