you won't find injectors for a "22R". that's a carbed engine. "22RE" or "REC" denotes an EFI engine. use that when shopping on line.
as stated, no, the V6 injectors won't work.
since we don't know the year (post or pre 85 block), plug your info into here, (in this case 22RE or REC - for injectors RE or REC are the same).

getting gas doesn't mean adequate pressure. flow, yes. so check fuel pressure regulator. do you hear the injectors clicking when trying to start. check ignition switch, EFI main fuse, or main relay (kick panel at your feet).
need to know the year to help more.
