Check the transistor

The inductor could also be shot. I've had this happen before.

how would I test the inductor

Im honestly not sure. I would swap a known working one to see if it makes it go.

agree it could be the inductor too

A continuity check across the leads will show a broken coil, more precise measurement is a bit trickier

More likely you have a bad joint or trace somewhere inline with the inductor or transistor

i have continuity between two of the inductor leads but not the other two....should i have continuity all the way around?

The inductor and it's traces are the first place to start looking, and it depends on which pins are continuous and which ones aren't. They usually have continuity in matching pairs
1 - 2
3 - 4

1&2 have continuity as well as 3&4
or
1&3 and 2&4

Depending on which inductor you have - you might need to rotate it 90 to get some "wah"

Yeah, you might have it rotated 90 off.

Would be helpful to indicate what inductor you have if that doesn't fix it.

okay....so here's a picture of my inductor...i marked the two leads that have continuity together with a red marker, the other two don't have continuity....which way should this be positioned on the pcb? Or is my inductor shot?

No continuity should have been soldered to circuit, continuity solder to the bottom 2 holes if you haven't figured it out by now in case the inductor is good.
