If the engine refuses to start after cranking during a fire, what is the next step?

In the context of responding to an engine that refuses to start after cranking during a fire, the most appropriate action is to ensure that the throttle is full open. This is a critical step because opening the throttle allows any residual fuel in the engine to escape, potentially reducing the risk of a fire escalating. It also helps in clearing the engine of any flooding or excessive fuel that may be causing the starting problem.

Maintaining the throttle in the full open position can assist in controlling the situation effectively, and it is a standard practice to minimize fire risk. Ensuring proper fuel flow and minimizing flammability are key safety protocols in such scenarios.

Other actions, such as contacting the tower or calling for emergency assistance, can be beneficial in certain circumstances, but they do not directly address the immediate danger posed by an engine fire that is not starting. Taking off is not advisable unless the engine is operational and safe to do so—it certainly would not be appropriate in a situation where fire is a concern.
