If the EDP fails, what will happen to fuel pressure?

Explanation:
The engine-driven fuel pump is the primary source that maintains fuel pressure in the system. If it fails, there’s no active pump to push fuel into the lines, so the pressure in the fuel system quickly drops as fuel is consumed by the engine and any leaks or returns dissipate the remaining stored pressure. Without a functioning pump to replenish it, the pressure falls rapidly. Some systems may have an emergency pump or an accumulator that can hold pressure briefly, but the immediate effect of an EDP failure is a rapid reduction in fuel pressure.
