If oil pressure exceeds 128 psi during start, what action is required?

Explanation:
When oil pressure reads higher than the specified limit during start, it signals a lubrication-system fault that needs professional inspection. The pressure should come up to normal levels as the engine spools, but exceeding the limit suggests issues such as a faulty relief valve, pump problem, or blocked passages. These are maintenance concerns, not something a pilot can fix in flight, so the correct action is to refer the aircraft to maintenance for a thorough inspection and service before further flight. Increasing RPM, ignoring the reading, or opening the fuel valve will not address the underlying lubrication-system fault and could lead to engine damage.
