Most likely the RCM ( relay control module ).
There are 3 modules in the box by the battery ( BCM, PTCM & RCM ), the RCM is the one closest to the engine.
see the "Mystery No Start" thread, and use a GOOD magnifying glass to inspect the 3 solder pads.

Re-solder it yourself, or send it to DJ ( tighed1 ) for a fix.
