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.

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.
