7 Reasons Direct-Injection High-Pressure Fuel Pumps Fail
Don’t be scared by direct fuel injection diagnostics. In theory, these systems operate on the same principles as port fuel injection, but direct injection can inject more precise amounts of fuel into the combustion chamber so the engine can run leaner and more efficient. The key to direct injection is a high-pressure fuel pump. This
Driveability Diagnostics and Direct Injection
Direct injection is becoming standard on more and more late-model vehicles. These systems can be a diagnostic challenge, but with the right foundation, problems can be solved profitably. Years ago, all a low-level technician needed to diagnose a fuel problem was a set of “noid lights,” a fuel pressure gauge and maybe a meter. These
