Final answer:
A no-start condition on a HEUI engine can be caused by low injection control pressure, as this pressure is essential for the proper operation of the fuel injectors.
Step-by-step explanation:
The condition that can cause a no-start condition on a HEUI (Hydraulically-actuated Electronically-controlled Unit Injector) engine is (B) Low injection control pressure. HEUI systems rely on oil pressure to power the fuel injectors. This injection control pressure must be sufficiently high to inject fuel into the combustion chamber of the engine correctly. Insufficient injection control pressure may prevent the engine from starting because the fuel cannot be properly atomized or introduced into the engine's cylinders. Conversely, while high boost pressure might cause operational issues, and high fuel pressure could lead to other engine problems, neither of these would typically result in a no-start condition. Low boost pressure may affect engine performance and power output but usually will not cause the engine to fail to start.
