can't believe someone else used my little form thing... kinda makes me happy

anywho

check the resistance on the injectors, I think it is "supposed" to be like 11. something, but you typically won't have any problems as long as it is under 15. the other way to test it is to pull the fuel rail off, lay the rail on some cardboard and have someone turn the key and see if each injector sprays fuel.

If it is timing, then you'll get pops and/or backfires through the intake - if the dizzy is off a tooth or more.
if somehow the timing chain jumped a tooth, then you have all kinds of problems and just need to swap in a new engine and call it a day.

check the basics
compression - should be 180 give or take 5 all the way across, however, the engine will still start if the compression is low as long as it is pretty much the same on all 4, won't be a healthy engine, but it will still start.
spark - make sure you are actually getting spark
fuel - verify the injectors are actually spraying gas
air
timing. - this should help Distributor Timing
