Dodge Ram 2500 Problems

Locked up WCM may cause engine cranking problems on Dodge Ram 2500

Problem Description and Possible Solution

If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.

So truck will not fire pump will not turn on help me
No solution yet. Still stranded in parking lot. Truck ran fine. Shut off went in to grab a coffee and now it just turns over. Disconnected battery and truck started for 3 seconds and shut back down. Now it only cranks.
Was driving all day came home. Showered went to dinner. Got in truck to go home using remote to unlock. Got in. Turn the key. Nothing. Lights and radio worked. Battery was new and having lights meant no prob with battery. Heard fuel pump. Having no tools with me called father to bring mine. Researched my (new to me truck issues) wcm. Disconnected battery few seconds. Turned headlights on to clear circuit then off. Plugged battery back on. POOF. Started right up. Should be a recall.....
