The fuel pressure drops rapidly when the engine is turned off.

Technician A says that one or more injectors could be leaking.

Technician B says that a failed check valve in the fuel pump could be causing the problem. Which technician is correct?

A only,

B only,

both techs,

or neither tech.

The correct answer is C. Tech A is correct because the fuel pressure would drop if one or more of the injectors were leaking fuel. Tech B is also correct because the fuel pressure would drop if the check valve in the outlet of the fuel pump was leaking or has failed. Good luck on that test.
