I have BMP that I put together and is not working.  I am getting absolutely nothing.  I think there is some trouble getting power to the board.  I am feeling very overwhelmed trying to trouble shoot this.  Can anyone walk me through this?

Derringer

what makes you think that it's a power problem?

do you have a DMM (voltage meter) ?

Pictures of the build will help  ;D

Well then, we either need pictures, voltages, or this is gonna take a LONG TIME! I think you need to read this thread:

Yes...I will enjoy the long process

Also yes I have the DMM

Find the continuity setting on your dmm, when you touch the red probe to the black probe the meter should beep. Use this setting to ensure your wiring is correct. Start by probing the ground on the power jack to all other grounds on the input and output jacks, ground on the board and led ground. Probe the lugs on the 3pdt switch and toggle the switch in and out of bypass mode to make sure its wired correctly. Probe the pots, etc. Just probe everything and look for errors. 99.9% of the time its a simple wiring error.
I forgot what I was gonna say here.

I only have a meter with ohms...No beep.  Also can anybody give wiring diagram for the switch?

Different wiring diagrams can be downloaded from TonePad.

Also you can do the same tests that flintstoned mentioned with your ohmeter.  Just check that the Ohms reads 0.

Yeah I was aware of that, but was having some trouble until i remembered that capacitors don't pass dc so that was why my ohm meter wasn't working there.  Also I don't see the wiring diagram for the switch.
