Tech Tip: Diagnosing Fuel Pumps and Injectors
One of the first questions that should always be answered when diagnosing a fuel-related complaint on a fuel-injected engine is, "What is the fuel pressure?" All too often, technicians assume fuel pressure is "good" without actually measuring it with a gauge. If the engine runs, they assume the injectors are getting adequate fuel pressure. If the engine cranks but won’t start, and they depress the service valve on the ….
Tech Tip: Diagnosing an Engine that Won’t Start
For any engine to start, three things are necessary: fuel, compression and spark. If any of these components is lacking, the engine won’t start. The fuel system must be generating normal fuel pressure, and the air/fuel ratio must be correct for the ambient temperature and engine temperature. If the air/fuel mixture is too lean, it won’t ignite and the engine won’t start. If the air/fuel mixture is too rich, it can flood the engine and also prevent it from starting ….
