^Eatyourguitar is right. You wired the wrong lug of the input jack. Since you're not using a battery, apparently, you don't need a stereo jack.
Also, the DC jack is wired wrong. The lug that's connected on the outside (the one you don't have wired to anything) is the tip of the power supply. In a stompbox, it should go to ground. The lug you have +9V connected to is correct, I believe.
Also also, it looks like the LED is wired directly to the board and the DC jack... which would mean the LED is on all the time. The negative side of the LED needs to go to the switch.
So it looks like you got some connections mixed up. Not a huge deal, but it -is- pretty frustrating. Just the other day I wired a DC jack backwards and it fucked with me for a while before I noticed it... and I use the kind that only have two lugs. >.>
Here's a $15 (plus shipping) dollar meter:

90% of the time when I'm debugging, I stick one lead into the screw hole of an enclosure, and poke around at things that are supposed to be grounded first. The check power by putting one lead on the +9V and touch things I know are supposed to be connected there. Then it's just a matter of following the schematic... "Oh, these should be connected! ... *poke* *BEEP* Yay! What about these? *poke* *silence* THAT'S IT!"

But, yeah, if you're about to toss a $60 kit because you can't debug it, the meter is a pretty decent investment, doncha think? And you can save quite a bit building kits instead of buying pedals... (compared to boutique clones).
BTW, if you're just going to give up on that kit, you can send it to me and I'll get it working for you and let you know what was wrong with it.
