Engine issues!

Alright I need some other peoples thoughs and input on this, I have a 1993 7.3L IDI non-turbo. Finally got the engine to fire up and it's shaking the truck severely, I figured I could have a number of issues. Loss of compression, Bad injector(s), or ???. I verified fuel to all 8 injectors but have no means of testing them right now. Also when the truck is running I get choppy bursts of white smoke with blue tint from the exhaust. I figure it seams like I'm not getting compression on one or two cylinders. As I throttle up truck smooths out and noise quites down slightly.

Thoughts? This sounds like a fun diagnostics
