Here is what I think you did, and would explane the no start problems.
One thing before I continue, is to make sure that the CAM sensor is installed in the cam gear, and in the correct hole if your running a after marker timing chain set up, as there are many on aftermarket. Though, it looks like your stock if I am not mistaken.
Ok, you basically forced your balancer on, and did no align the balancer to the key pressed in the crank. You pretty much screwed up your balancer, and I wouldn't run it again myself. The key in the crank, I would replace that too. Its called a Woodruff key. Here is what the cutter that makes the groove in the crank, and what the keys look like: (google image search)
You can tap the key out with a flat bladed screw driver, or a punch to be correct, be careful not to damage the crank any more. It will not require a lot of pounding with the screw driver, or punch, and the hammer, and you don't want to pound hard, cause as it was said earlier, the crank thrust bearings will be taking all the abuse inside your engine.
The key goes in the same way it came out. If you cannot locate a key, I have some stock cranks that might still have the keys in them. I would be happy to send you one. The balancer, I would get a used one from ED. Morad Parts Company - 3800 Motors, Transaxles, & Stock Parts
If the little "windows" on the back side of your balancer dont line up how they should, then this can cause a no start/fire. The rest of your engine/PCM doesn't know where the hell the crank is positioned at because of your misaligned balancer. Get this fixed....and you should be good to go.
WHEN YOU INSTALL YOUR BALANCER...
set it on the crank, and gently turn it left or right while gently pushing in till you fell it engage the key. Once you fell it engage, push in more, and give it a tough turn left or right to be sure your engaged on it correctly. THEN install your crank bolt, making sure to add some RTV gasket maker to the back side of the bolt head/flange and to coat the threads of the bolt with your molly lube left over from your cam kit, and hand start the bolt, and run it in by hand, THEN run it in with a impact till the socket stops turning, waiting for the compressor to run, and catch up, building up pressure, then hit it again. The stock speck for the crank bolt is 111 lbs. ft. + 76* I believe. Its freaking over kill. Running it on with a impact like this, your good to go.
DONT just sit the balancer on the crank, and then hammer away with the bolt with the impact with out making sure the balancer is inline with the key. This is what will happen.
Good luck, and let us know if we can be of any more help.
