Yes, TDC1 is the lone mark separated from the group of three.

Also how do I tell if I have a DX, HF OR Si motor.

Your car is a DX, so if there was not an engine swap, go with that information.

If I have a DX, I align the pully up with the isolated mark, then the marks on the crack seem to align with the flat surface of the head. If it jumped a tooth. would it be really obvious that it doesn't align with the flat? Seems to be an area there that you could say it was lined up?

The same marks on the front of the cam pulley that align with the top surface of the head should also be present on the rear side of the pulley. I prefer to use the rear marks to position the cam pulley at TDC1 because I am more confident about the alignment.

I pulled the plugs. They were all wet with gas. I've got spark. If the timing belt hasn't jumped a tooth, what would be the next thing to check for being wrong?

Any CEL codes?
Is spark bright white? If so, the next step would be to compression test the cylinders.

This problem started with the rotor screw coming out and letting the rotor free wheel. I don't think this could cause compression problem in a car that was running fine before the rotor came loose.

I've changed the coil. I've got spark, although maybe not strong enough. What about the rotor coming loose would cause this problem? I don't remember a white spark. More like orange, but it was visible and audible.

There are no error codes. When I get it put back together again I'll check the spark again. Would the igniter cause a weak spark? Thanks kevin

If so, did you reconnect the plug wires in the wrong firing order? Any CEL codes? If all of this is fine, then your current troubleshooting effort is right on track.
