Inconsistent Spark

Before I go into all the details I would like to make it known that I have searched and diagnosed my car. Coil, Distributor, Spark Plugs + Wires, Starter, Battery, Cap and Rotor have all been replaced.(Not completely for this reason, but due to maintenance) I've checked for continuity on all wires going into the dizzy and they all check out.

I recently did a Head Gasket(Head was machined) and timing belt(everything is properly timed). Compression test checks out and there it proper fuels pressure.

The problem I'm having is that I'll occasionally get a spark, but when I do it's rather weak. Every so often after cranking for several seconds it'll begin to spark more and more and eventually start the vehicle. I'll be doing a test with an analyzer tomorrow to hopefully see if the ECU can point me in the right direction, but until then I'm out of ideas. Has anyone seen or had this issue before? I'm thinking poor connection in the wiring harness or something of that nature, but the fact that there is continuity and proper voltage on the lines heading to the dizzy kinda washes that idea away.

Should also mention that I've check for spark at the plugs, wires, dizzy, and coil. Its weak all the way to the coil.

Any help would be greatly appreciated =]
