Trooper firing on only 3 cylinders. Need suggestions on what is wrong.

Same belt as on the Honda Passport--Maybe same insane procedure for cam positioning too? All I know is there were several different positions for the cams to go , and still line up with the marks , but only one position works.Single pulley on outside , but twin cam ,gear driven inside. Have crank OFF top dead center to set cams Turn pass side cam and let it 'jump' to its' own stop (maybe 3-4 times) until the mark lines up. Same routine on drivers side except I think the mark stops just a little before the spot on the backing plate. ............Factory service manual would REALLY be good , cause I could be wrong!!!!!!!....Good luck.
