What to do if my Kohler 7.3ECD Marine Equipment cranks but does not start?

If your Kohler Marine Equipment cranks but doesn't start, start by checking the fuel supply. Then, inspect the spark plugs, wires, and connections, replacing or cleaning and regapping the spark plugs as necessary. Look for loose or open connections at the fuel solenoid and engine control module. Ensure the backfire flame arrestor isn't clogged by cleaning or replacing it. Verify correct controller configuration parameters, specifically the unit configuration (UC) and engine configuration (EC). Test or replace ignition system components if needed. Also, check and replace F2, F4, and F5 fuses if they are blown. For F4, check GNDs on coil. For F5, check ECM ground connection pin 14.
