Locked up WCM May Cause Engine Cranking Problems on Dodge Ram 1500

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.

Stopped at the Post Office. Got back in and turned the key....nothing. Radio and lights worked. Came home and read this thread, went back and disconnected the negative battery terminal. Waited a minute and hooked it back up, turned the key and Wahoo! It started up again. Thanks so much for the solution here!! :)

Same problem here! It's happened three times so far latest one yesterday 3/1/2011. After owning 4 Dodge trucks and our local Dodge dealer closing down this is the last one I'll ever own. Closest dealer is 122 miles away, truck went for repairs to this dealer last week for a different problem; coil igniter failed causing missfire to cylinder# 6, messed up two spark plugs, had to go get it at my own expense. Sorry Dodge!

I have a 2011 Dodge Ram 1500 truck and I'm having issues with it not cranking over. Have it with the mechanic waiting on an answer on what the problem is.

Had truck towed to dealership because it would not start. Spent $306 for WCM and $337 on labor. Picked up truck and immediately the tire pressure light was on. Thought I needed air in the tires, all four tires had the proper pressure. Called Dodge to report the problem the next day and left messages with the service rep who did not return my called. Called back to get the service manager's name, called him and left a message and again, my called was not returned. Called and asked for the service manager's manager who I was immediately transferred to. Now have to return the vehicle to see why the tire pressure light is on. Probably more out of pocket expense. REALLY?

Symptoms: Everything works except door locks and ignition does nothing when turned. Doesn't even click. No symptoms prior to it failing. Have had truck since 70k and never had this problem. Fix: Pulled ground cable off battery for a couple minutes to reset. Just for good measure I also pulled and checked the door lock fuse & the ignition fuse. They were both good. Reconnected the negative and it started right up.

4-22-15: Wife stopped for gas and truck would not turn over. Lights stayed bright and no relay clicks when she turned the key. Volt meter stayed in the normal range. She jiggled the shifter in park and neutral and no luck.It finally cranked after about an hour of trying. Has been working fine for the last two days, but she doesn't trust it anymore.

Turn the key, all lights, gauges, radio work, get a click, but no engine turn over. After trying many times, it will eventually turn over and start. Has been happening off and on for a few years.
This is wrong sta te for us. Please remove us from your email list. Think it's all from Google ada. So sorry
Just spent 1,200 dollars for fuel pump and new timing chain gasket and seals. Had one day now truck will not start, no crank lights on dash but will not crank. Happened on and off for the 9 years i have had truck ! Always started after a while. Not looking good now. Looks like tow back to dealership again. Might be my last dodge. Very disappointed!

They've replace the wcm 3 time and still have to remove battery cable and reset. All I get is clicks when trying to start, the red light flashing no dome light. I know it won't start if there is no dome lights come on.
