If it were me in your shoes after all you've done so far I would first run a jumper wire from the batt terminal to the battery and try to start her. Then, if it doesn't start, I would pull out a spark plug, plug the wire back on it, ground it( I use a jumper cableon the neg batt terminal on one end and grab the spark plug body on the other end, makes it easier to do by yourself) try to start it and check for sparks. If no sparks, you have eliminated the wiring to the dist. Then I would pull the cap and check the dist wiring, make sure the ground strap was in there, check the module. While you are in there you might spin the engine and make sure the rotor turns, etc.
Also, since you say you installed a tach, you might uninstall it and try the engine then.
Good luck.
