Escort 1996 1.9 sefi

1996 1.9 liter SEFI canadian First of all, i'd like to know if these are freeweheeling engines ? Second: i have this strange problem ....went to grocery store stopped engine
(was working fine) 15 minutes later got back in the car start the engine ,it would not start at all unless i keep my foot on the gas pedal ,and there was a stange knocking noise ... Got it itowed at home, Checked Timing belt marks... right on their spot ... Compression cyl 1 150 cyl2 160 3 0 cyl 4 0 Then i tried to turn the engine with a ratchet , it only moves that much : let's say close to 90 degrees...... from side to side ... Since i had compression on only 2 cylinders i figured the camshaft was broken in 2 .... well, it does'nt look like it So then i backed off the nuts from the rocker arms of cylinder 3 &4 , just to make sure there wasn't a valve sticking or something like that ,... it doesn't look it either....... I am very confused about this problem .... I figure that if there was something wrong with the cranshaft , it would be seized and would not move at all ...am I right ?? So basically , i'd like to get some tips about that problem Has anyone ever experienced this ??? SO far , i can not why this would happen ! Any help would be appreciated Regards Pat P.S. Sorry guys about my poor english.....
