To make things easier, pull all 5 spark plugs until you are finished. You will want to turn the engine by hand 720 degrees to make sure the valves are not hitting anything anyway.
With the Tbelt still on, place a long stick or screwdriver in the #1 plug hole and when you get to the crank marks, the piston should be at TDC.
If all of the marks are lined up and #1 is at TDC, you might well have a bad CPS. Have you taken it off yet and at least cleaned it up?
