WAIT WAIT WAIT.
you don;t need to rotate ANYTHING after you get to TDC because the crank and cam are already lined up. You just need to reinstall the crank and cam sprokets 12 oclock and 12 oclock. THEN make sure the pulley/dampener is INSTALLED at TDC on the timing cover.
If you ahve not pulled the dist, then you don;t need to degree the camshaft or rotate it.
If you rotated the camshaft once you got the crank to TDC, then you will be on a wild goosechase

Answer this question:
When you were doing any of this, did you rotate your camshaft when your timing chain was not on the cam AND crank sprokets?

I know the gear was on it, but was the CHAIN on it.

OK, that is the problem. If you turn the cam, then your intake valve will NOT be closed! You are moving the valvetrain.
Since you said you did not take out the distributor, you should have the rotor pointing to #1 when you are at TDC.
Did the cam slide out at all then you needed to put it back in?

Here is what to do, wait for editing....
With the chain OFF:
1. Rotate crank until the piston is at the top.
2. Rotate the cam until the intake valve is fully closed, the rotor should be pointed to the #1 cylinder on the distributor.
3. Take off the sprockets and REINSTALL them at 12 oclock and 12 oclock Do NOT rotate the engine to do that.
4. Install the chain and timing cover
5. Install the balancer/pulley lined up with the TDC mark on THEM and the Timing cover.
It should fire up. The reason it was not firing and you had no compression was that you were changing the valve position (open closed) when rotating the camshaft to line up the doots when all you needed to do was REINSTALL the sprocket in that 12/12 oclock position (assuming you were at TDC when this all started). When doing the timing chain, you just install and reinstall the sporckets in the SAME POSITION as you started. People usually put the engine at TDC before they do the swap.
If Step 2 does not yield the rotor pointing to #1, then something is wrong and you might need to pull the distributor. But only do that as a last resort and wait for someone other than me to chime in.

Ok basics 101
1:The intake stroke is, intake valve is open and the piston is in a down stroke
2:comp stroke both valves closed piston moving up, spark is added at tdc
3 power stroke ign and the piston is moving down, both valves closed
4:exhaust stroke, exhaust valve is open and piston is moving up.
