When I tested my coilpacks for resistance with a multimeter the only time I would get a reading other than infinity was between the + and - terminals which read 0.002 ohm. I tested between the three connector pins and the output to the spark plug..

Does this mean my coilpacks are bad?

Does it sound like it's missing?

pull the coilpack.

pins:1 2 3 (notch is over #2 pointing up)

check resistance across 1 and 2. it should be about 1 ohm.

I followed 180fan's directions and all of my coilpacks ended up right around 1 ohm, between 0.9 and 1.1 ohms.. Does this mean my coilpacks are good? I still have no spark
