restorer280zx

I have an '83 280zx and i pulled it in the garage to change the plugs and pulled the dash out for painting. Since then it hasn't hit one bit of fire. I have replaced the ic module, plugs, wires, ignition, rotory button, distributor, distributor cap, and checked all wiring twice with ohm meter. Now, riddle me this, what the heck did i do to my ride? Oh yeah, and i have put three different coils on it. Any masters of the z had this problem before? E-mail me with any chances of a solved problem. thanks, charles
