start with a compression check, the tool can run you around 25 bucks at an auto parts store. do that first, before checking into anything else. no use in spending money on ignition of fuel system if you have low compression numbers..

compression check was the first thing i did when i got the new head on.. there is 125-150 Psi of compression on each cylinder

anything 150 is considered to be not very good compression!! but you should still get spark on any cylinder above 90 on compression... So your next step would be, look into the ignition stuff, when diagnosing a problem you always want to start at the end and work backwards, so what i would do is check your plugs first, make sure the gap is good and they are clean... then look at your wires, make sure you are getting spark at the end of the wire and make sure your wires are not shorting out or arching out before the plug end. then clean or replace cap and rotor if situation still persists. And after you have done all that the last think would be to check your coil and ICM. JDMLyfeStyle has a write up on how to test those units. It is on this forum somewhere!!! good luck to you. And you also might want to look up the stock compression ratings for your engine, because that sounds VERY LOW
