There is one additional thing that my EVC has, I'm pretty certain the B34 has, and Craig yours might have too...
When the engine temp is below a threshold temperature (I can't remember the number but 70F rings a bell) a brief tap on the upper right button elicits a beep and sends power to the glow plugs (and a glow plug icon appears on the tach LCD while this is happening). After a few seconds the icon goes away, and then you can start the engine by holding the upper right button. You can override this by holding down the upper right button, but then you're starting the engine with cold cylinders and it's a longer and harsher turnover.
Craig, you should give this a try. Or does your engine not have glow plugs?
