Answers :

Before you start self repairing, you really should by a manual with proper diagrams to prevent heading in wrong directions.
\015\012The PCM doesnt control injector POWER. It controls injector GROUND. The POWER comes from the ignition switch and goes thru a fuse in teh fusebox probably marked ECM1 or ECMa. If you have power at both sides of that fuse with the ignition key in the ON position, then you have a broken wire between the fuse and the TBI. If you have no power to that fuse, you may have a broken wire, blown fuse, or defective ignition switch.
