Thanks folks!
I looked at the connector under the dash briefly. It looked quite different than the connector on the 'Stang, so I didn't persue it.

This problem came on very suddenly. The variables involved were a fresh fuel tank fill up. A, that day, detailing of the engine, and finally, a borderline insane nieghbor who I suspect of random acts of sabotage. I have caught him planting nails, and breaking bottles in my gravel driveway. I'm hoping he didn't sugar my tank.

In response to these variables, all connectors have been disconnected, blown clear, and dabbed with silicone diaelectric. A fresh top off with high-test, and a bottle of injector cleaner. Finally, as stated earlier, fresh plugs, fuel filter, PCV, coil-packs, and plug wires checked for resistance.

My scanner is an Actron III, CP9016, code reader. EEC-IV MCU compatible.

Again, thanks for the help!

I can't help with the other stuff, but the sugar in the fuel tank thing is not a problem... First, the sending unit sits in a reservoir stamped into the bottom of the tank. (That's that little teardrop stamped in the bottom of the tank). For the sugar to get in there, it would have to work its way through a convoluted tube while sloshing around in the bottom of the tank... not likely. Second, there is a pick-up screen on the filter that should filter out 99% of the miscellaneous crap that gets into the reservoir. Anything that makes it through that mesh filter will not damage the fuel pump, and will get caught in the fuel filter. If it gets through the filter, it's not going to hurt the injectors.

Also, you don't need to worry about the sugar dissolving in the tank... sugar isn't soluble in gasoline.

(You didn't hear this from me) Now, you wanna mess something up, use antifreeze... ehtylene glycol is a complex sugar, and will flow right past the fuel filters into the engine, then turn to carmel inside the engine... NOT a pretty sight...

Back to the problem at hand... It's totally possible the tank at the gas station was low and you pumped some water into your tank... it happens all the time, and most places carry insurance that will cover that problem. However, proving it is difficult... try putting a few bottles of dry-gas (isopropyl alcohol) into the tank and see if it clears up. That's the easiest place to start.
