ABSTRACT:
An engine system includes a status determination module and an open-loop fuel control module. The status determination module determines whether a first ignition fuse is in a failure state. The open-loop fuel control module disables a first plurality of fuel injectors and actuates a second plurality of fuel injectors based on a first air/fuel (A/F) ratio when the first ignition fuse is in the failure state, wherein the first ignition fuse and the first plurality of fuel injectors correspond to a first cylinder bank, and wherein a second ignition fuse and the second plurality of fuel injectors correspond to a second cylinder bank.
