Re: blown coil pack
What test did you use to determine they were bad? Make sure by removing the 2 wires attached to 1 segment at a time, start (or attempt to) and watch the spark jump across the open terminals. If all three segments do this, the coil pack is probably good. If good, measure resistance in your plug wires, check the coil connector, replace spark plugs, etc. Plugs and wires are cheap, install proper replacements and reduce possibilities.
