Sounds like the cams are in wrong to me...
DONT keep trying to turn it over as these are tight tolerence motors and you dont want to crash the valves into a piston. Study the cam timing closely as well as if the cams are in the right place (intake/intake) and (Exhaust/Exhaust).

Yep, the cams are probably 180 degrees out. If they are you should be able feel suction on the exhaust outlet.

If the XJ rotor is used when installing the cams, which is 180 degrees off from the FJ rotor and the US service manuals are written on the FJ timed rotor, that is the cause.

I did that once...
