Engine swap

First of all you have to check for voltage to the ignition coil while cranking the engine, not just with the ignition switch turned on. Second, six years is a big difference. Which flex plate did you use, the original '96 or the one that was used with the '02 model? They will likely have different cutouts for the crankshaft position sensor to detect. If the Engine Computer doesn't see the right signal from the crank sensor it won't turn on the automatic shutdown relay which powers the ignition coil and injectors.
