tell a little more about not starting - does it sometimes sound like it kicks up higher, then falls back to normal cranking speed? that would indicate a lack of fuel issue. where did you get the ignition coil (condenser) from-new or used? did you replace the ignitor module as well (they have a history of taking each other out in toyotas, gm's, hondas, etc). have you tried adding an alternative fuel (brake cleaner, propane) as you crank? also, remember that <i>spark</i> is <b>not</b> the required factor in a running motor. combustion is. I have seen lots of cases where there is a weak spark, but not enough to light off the cylinders.
(this next paragraph is why you don't drink and diagnose, folks)
just read your second post thoroughly, and now I feel dumb. you have an enleanment problem. I'm pretty sure the '92 has a cold start fuel injector. You can find it on the intake manifold in the center facing the front of the car. it is a two pin Bosch style connector, it is only active on cranking, is a simple circuit from [crank position on ign switch] to [two pin coolant temp sensor on back of motor] to [cold start injector] to ground. the coolant temp sensor (there are 3) has either brown or black plastic on it (forget which) and heavier gauge wires (~16ga) running to it. You should start by disconnecting the connector from the injector and putting a 12v light across it. try starting in the cold (below 53 degrees) and it should light up. if it does, it's working and something else is wrong. if not, that's your problem.
