    take the coilpacks off (leave plugs in), and hook up to a spark tester...

    There is another way to do this, not the safest way but there is another way. Take the spark plug out and ground it (hold it against the engine somewhere) with the coilpack obviously on so it is able to receive timing. Have someone crank the engine and see if a spark appears. DO NOT HOLD SPARK PLUG AT THIS TIME. Make sure you are holding on to the rubber boot of the coilpack. If a spark does not appear it is time to start to look at the coilpacks. If there is still no spark put the ignition key to on (acc) position and check the coil pack for voltage. Make sure that is actually voltage going to the coil pack on the spark plug side. After that things start to get a little hard. You are going to have to start and checking the crank sensor and timing. Have you recently replaced anything? There may be a tooth missing in your crank gear, the timing belt may not be positioned properly and things like that. If there is actually no spark it is a lot harder to diagnose, because now you have to start checking sensors and everything else.
