Since code 27 is a general trouble code for fuel injector issue, it could be for any of the 8.
Do the following:
With the engine OFF, key OFF, disconnect the electrical connector for a fuel injector.
Using a multimeter, test continuity (ohms) across the two pins of the fuel injector. You should get 10 to 16 ohms. (Service manual lists 14.5 ohms +/- 1.2 ohms at 68*F) If the ohms are not within these limits, the fuel injector needs to be replaced.
If the ohms are within limits, you will need to check wiring (ohms) between the fuel injector electrical connector and the computer; and the fuel injector electrical connector and the Automatic Shutdown Relay (ASD).
