2010 Fit. Got the following codes a few days after a drive through car wash, car won't start / EPS light is on. Battery (new, 3 months old) is at 12.6V, cannot jump start car. Got the following DTCs. Can a blown fuse prevent car from starting? no cranking when key is turned, but lights come on, electrical system seems working. Thanks.

Check the 80A fuse (for the whole box) & the 50 A fuse in the under the hood fuse box. The 50A is the main ignition fuse. Also check other fuses associated with ignition & starter you can find in the fuse charts.
