VIDEO: Direct Injection Fuel Pump Killers
In this video, Andrew Markel covers how a fuel pump can fail. This video is sponsored by Carter.
7 Reasons Direct-Injection High-Pressure Fuel Pumps Fail
High-pressure fuel pumps can malfunction and/or fail due to a number of factors.
Direct Injection Logic: How The High-Pressure Fuel Pump Solenoid Works
A direct injection fuel pump can’t increase its speed independent of the engine to increase it’s output or pressure, so it has to control the volume of fuel that is compressed. This relationship is what makes direct injection high-pressure fuel pumps a mystery to some technicians and even engineers. But once you understand the relationship between the pump and control solenoid, your diagnostic skills will grow.
BMW Extended Warranty On S63 Direct Injection High-Pressure Fuel Pumps
BMW has extended the warranty on the high-pressure fuel pump for the 2012 X5 M and X6 M models with the S63 engine. The warranty covers the pump for 10 years or 120,000 miles. BMW is not recalling the pump and no reason was given for the extension of the warranty.
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
High Pressure Direct Injection Fuel Systems
The main destroyer of high-pressure fuel pumps is a lack of oil changes.
Gasoline Direct Injection Technology
Gasoline Direct Injection technology has been a key part of improving fuel economy and reducing emissions since the early 2000s. This video is sponsored by Standard.
Today’s Fuel Pressure Diagnostics
Direct injection pressure is measured with sensors, and you’ll need a scan tool to measure the signals
A Closer Look: Gasoline Direct Injection (GDI)
Gasoline direct injection (GDI) is used on most new vehicles and requires a different approach to diagnosis and service. GDI technology has been an integral part of helping to improve fuel economy while reducing emissions, and can be found on more than half of the U.S. fleet. In fact, the use of GDI engines has
Fuel Pumps and Cranking
Diagnosing the problem comes down to understanding what causes a loss of fuel pressure.
