Your signature says 04 so are you posting in the wrong generation? Do you have a LB7 or LLY
It is very rare for a FICM to go bad on a LLY engine LB7 yes -- shorted wires on the FICM bracket-very common.
When a fuel injector circuit condition is detected by the FICM, all of the fuel injectors on the affected ignition voltage circuit will be disabled.
If a circuit condition is detected on a fuel injector circuit for cylinders 1, 4, 6, or 7, DTCs P0201, P0204, P0206, or P0207 will set, along with DTC P2146.


Proper way to check balance rates

Bad injector won’t cause limp mode but P2146 will
