1987 Olds. Delta 88, Spark problem

As stated I have an '87 Delta 88. I recently went through the process of replacing the timing chain, and the cam and crank sprockets, because of some dying/stalling issues that I had.
After doing that, the car ran perfectly for about 15 minutes. Then the dying came back. Low and behold it was the Crank Position sensor, out of wack. Somehow with it being so loose, it managed to break the bracket and the sensor. I replaced both and aligned it properly. Now it won't even start. By start I mean, its turning over but nothing.
I checked every sensor...and found out it has something to do with the Coils. My question is, one side of the coil module works(could be called ignition module, the part that the coils bolt to), but the driver side and middle do not work, only the passenger. What would be the problem? I will post further information if needed.
PS I get spark only from the passenger side coil terminal, and its not the coils, because I switched them around and only the passenger side gave spark with switching all 3 coils.

What do you mean by this? Drivers side of coil (right side when looking in engine bay) and middle (middle coil) doesn't give spark anymore?
Did you have the ignition module tested (o'reily or autozone can do it, 3 11mm bolts hold it on)? Did you test the coils (have friend crank on the engine, use INSULATED pliers to pull plug caps off coil to check for lack of spark or erratic [arcing to one side] spark)?
Is she throwing any codes/ses light? Neither Coil nor ICM give codes (usually). Another indicator of problems in this area would be a car shuddering or jerking around 50-60MPH and generally poor accerlation.

Sounds like the ICm, however if one side doesn't fire, the other side shouldn't either. I'd suggest replacing the ICM and coil packs. Try one from a junkyard forst just in case it doesn't solve the problem.

Junkyard electronics are not your friend. No telling how old they are or for how long they have been sitting.
