Bike won't fire up

[lifesuck]

Bike won't start.
It works absolutely normal before I touched it. This is what I did:
1. Changed both front and rear brake pads, lots a couple of drop of brake fluid (now it's 1/8 inch below the "Min" line). But the brake works just fine.
2. Replace the stock tail light and blinkers with the integrated taillight. When playing with the wiring, All the fuse blown (all lights, horn, injection) except for the master fuse 30A on top. I replaced all the fuses, now all the above works, lights' on, heard the zzzzzz sounds (fuel injection) after key on...

However,
It doesn't fire up eventhough it click click click and crank over, everything sounds like normal, exactly like when your bike is running out of gas. (However, it has gas). It just doesn't fire up.
I've read all threads about starting and made sure all the cable, plugs are tighten, battery fully charged.
I'm just wondering if I happened to DEactivate anything when the fuses blown, that I need to REactivate it, or anything might went wrong after I did the 2 above.
Please advise. I don't want to pay 200 bucks just for the guy to take a look at it and fix a simple thing.
Anything is appreciated.

and the run switch is on? You checked the relays?

[lifesuck]

Yes, the switch is on, and even kickstand up too.
What about the relays that I have to check. What does it do to the starter? if the relays are on, it works like I described above, but if I take it off (both)
and key on, switch on, kickstand up, bike is in neuture, press start button, yet nothing happen (not even click and cranks)...

Awesome! I've been trying to clean cable/plugs, charge, check fuses for a week...Hope for the best, will def try new relays tomorrow. In the mean time, please input if you can think of any other causes...
Really appreciate guys!

Have you pulled the plugs out to see if they are sparking? Pull them, plug them into the wires and lay them on the head or cooling fin to make ground. Then turn over the engine with the start switch. If you have spark then it isn't electrical. No spark, check all the fuses again. If you have spark, then spray a little ether (AKA starter fluid) into the cylinders and quickly put the plugs back in. Try and start it on the ether. You can also spray a little directly on the air filter.

So I paied $120 to tow it to the shop and cost $100 to fix and basically they just changed the spark and it fire right up.
I should have done caferacermike's advice, I just didn't have the tools at that time. Lesson learnt: invest on tools.

Thanks guys for all the advices. Ride safe in the cold!
