if you are sure that the wiring is right and there are no blown fuses then its time to try a puter.

first try to narrow it down before you start changing parts...use a volt meter and see if you have power coming out of the ecu for the ignition circuit to the coils..i think is is a blue and red or white wire in the main harness...should be the only thick blue wire with a stripe..that comes from the ecu and pwers the coils..you may have wire that shorted that you missed...also check all of your grounds
