Hello, I have a 2.0Mhz (2 pin ) crystal. I would liek to havr it oscillate so i can incorporate it inta a circuit. I tried puting one leg to Ground and the other to Vdd but nothing. How do i make it oscillate

Your crystal is an electromechanical resonator. It must be combined with gain and feedback, to have it take part in an oscillator.
See:

Then you incorporate it into the circuit.
It's a passive element, and if you want it to oscillate, you need to incorporate it into an oscillator.
Of course, if you'd gotten a 2MHz oscillator, then you'd incorporate that into whatever you are building.

If it were oscillating, how would you know it?

On my scope, Ok so i will a feedback amp. thanks
Also, check Google for "crystal oscillator."

But your scope would be connected from ground to Vdd, right? So you'd be seeing Vdd.
John
Or a small oscillation pushing Vdd up and down.
