Curing Intermittent And Chronic Fuel Pump Failures
The fuel pump may be one of the most misdiagnosed components on a vehicle.

Ethanol & Fuel Systems
Here’s what you need to know about ethanol and E15 fuels.

High-Pressure GDI Fuel Pumps
When solving a fuel pump issue, the scan tool is your best friend.

Fuel Tank Contamination
A number of things can cause a fuel filter to plug up.

Oxygen Sensors And Catalyst Efficiency
Newer air/fuel ratio or wide-band sensors can detect a wide range of fuel conditions.

Gasoline Direct Injection Is Better, But Not Perfect
GDI technology has improved but drivers could face problems if they don’t keep up with maintenance.

Fuel Pressure Diagnostic Service
Use a scan tool that can look at special direct fuel injection parameters and perform bidirectional tests.

Fuel Tanks and Pumps
The behavior of the fuel wells, pumps & sending units are often misdiagnosed, leading to fuel pumps being replaced.

Drivability Issues Fuel Trim Diagnostics
No code diagnostics are some of the most challenging drivability issues.

Seasonal Fuel Blends
The cause of the misfires is the temperature fuel evaporates, otherwise known as the volatility.

Diesel Fuel Injectors
The purpose of common rail injection is to deliver high-pressure fuel to the injector.

Overheard: Gas Goes Up; Diesel Down
The average price of #2 Diesel Fuel in the U.S. was $3.13 in April, down two cents from March.
