I would suggest the same as Rob,
I've had the same thing happen to me a few weeks ago. My car is in for winter storage and I start it once every few weeks during the winter. A few weeks ago after starting it up the idling was a little wonky then all of a sudden it just stopped running and stalled.. I turned the key and there as absolutely nothing.. Nothing wrong with the voltage as the lights were strong etc... I had removed the Rcm last year and soldered it as I had noticed some weak spots.. Hence I removed the Rcm again this time... Looked at the solder joints and they didn't seem bad but soldered pretty much every joint on the board just to be on the safe side. Installed it back in the car and it started right up... No problems.. It's a quick and easy fix so if that's your issue for the no start.. You will be running in no time... So yes I would also say that it should be the first thing to do before diving into more complicated fixes...
Best of luck.. Let us now how you make out.
