Well, in that case you should start from first principles.
Turn the crank to line up the pulley mark with the TDC indicator. Make sure
cylinder #1 is on the compression stroke (I'm sure you can figure out how to
determine that).
Follow the spark plug lead from the #1 spark plug to the distributor cap,
noting its relative position. Remove the distributor cap and note where the
rotor is pointing -- it should be pointing roughly at the #1 lead, or a
little after it (5 to 10 degrees would be close enough).
If you aren't sure which direction is before or after, recall that the
firing order is 1-3-4-2. Or look up the direction of rotation in the manual
(I'm sorry, I can never remember when I'm not actually looking at it).
That should tell you whether the timing is close enough to have a chance to
fire up. After that you will have to determine if you are actually getting
spark, etc.
