ignition troubles

ok i have been tryin to get my 92 FI b2200 truck runnin properly for a while now but with no luck:( It would run somedays really well and then the next really bad. Noticed there was a leak in the cab and water may have been dripping on the ECU. So i pulled it out to have a look but wasnt too sure if it was good or bad so i just put it back. But after that the engine just stopped runnin all together. Found out it wasnt sparking. Checked the resistance of the ignition coil and it was fine. Replaced the distributor with a known workin used one and still no spark from the coil to the dist. I have 12v on the positive side of the coil with key on and around 10 or 11v when crankin the motor. Even if the computer was bad shouldnt i be getting some spark? any help is appreciated

one of you block to frame grounds bad maybe?

and just because the coil has power doesnt mean its putting out spark.

on the coil there is a plug with two wires. I am assuming that one is the power wire and the other is ground cause with the key on I get the 12v on one but i dont have continuity to ground on the other. But with the key off the same wire that had the 12v now has continuity to ground. This doesnt seem right to me

ok i was lookin things over by the coil and i was just wondering what this thing with the gray plug was. I was looking at a wiring diagram and someone suggested that the ignitor might be the problem and i thought this might be it but not to sure.

So what did you ever find out. Sounds like exactly what I have wrong with one that I own.
