Yes, a no start condition is a symptom of a bad NSBU switch. (Check you truck for codes and see where this leads you...could be a bad NSBU)
Fuel economy can vary based on driving conditions, vehicle loads, and driving habits. Most users that don’t’ tow, or tow light loads infrequently, report that they get the best fuel mileage on the higher HP settings. The best way to determine the optimum fuel economy for your vehicle and driving conditions is to try each setting.
A service engine light message that reads "shift range inhibited" is a sign of a bad NSBU switch.
Signs and symptoms of a bad NSBU switch also include (but are not limited to):
No Start
Codes: P0700, P0708, P0847, P0872, P0875, P1711 & P1713
PRNDL (Park, Reverse, Neutral, Drive, Low) not displaying on dash
Engagement issues with the transmission
You may have to go over all of your connections and be sure the NSBU remains in the neutral position. The metal clip (neutral assurance bracket) on the switch helps to ensure the switch is properly aligned to the shaft.
