X100 appears to be a simple crystal rather than a crystal oscillator. The latter incorporates electronic circuitry wherease the former does not. That said, pins 1 and 3 should be biased at a DC level corresponding to half the supply voltage of the flash controller. Furthermore, I doubt that a multimeter has a frequency range in the tens of MHz. Instead you would need an oscilloscope.
I expect that the circuit looks like this:
