Timing bellt 2004 Huyndai Santa Fe v6 3.5 DOHC

Use wood wedges to hold the cams in place and did not work.The camshafts sprong out of position when changing the timng belt. Got all the marks aling according with the repair manual, but when try to turn the crankshaft the two revolutions it stops after 1 3/4 revolution.
What does that means?
If I take the belt off the crank turn with no problem. All cams do rotate but after a revolution or so it stops. The manual says to try alining everythig and instal the belt again. I have done so about 6 or 7 times with no luck.
What am I doing wrong?
