Ed, you NEED to pull EACH plug out and inspect it.
When we spoke today you didn't tell me about the wire hitting the fan........that sounds like bad business.
That car is wired quite "uniquely" , and we've known about that water pump for quite a while, you really need to fix that. Large fluctuations in heat WILL wear those head gaskets much quicker than normal heat cycling. Not only that, but your intercooler pump is wired in series with that WP, meaning when you lose WP, you loose intercooler. And with that 2.5" pulley on that blower, well, lets just say you generating a lot of heat.
I will also reiterate what I said earlier: I've seen coil packs go bad and STILL give spark. It's just not good enough spark. You may need to get some low mileage ones and replace all of them.
pull each plug and inspect, then go out and buy some starting fluid and spray it into the TB, see if it wants to start up with that............
That alarm system, hell, that whole car's aftermarket electrical system MUST be re-wired. It's going to be a PITA , but totally worth it!!!!!!!!!!!!!!!
