How To Diagnose GDI Fuel Systems

Free Webinar: How To Diagnose GDI Fuel Systems

You'll learn how to diagnose the entire fuel system of a GDI vehicle. This webinar is sponsored by Carter.

ShopOwner and Tomorrow’s Tech will present a free, interactive webinar on Wednesday, October 19, at 2:00 pm Eastern/11:00 am Pacific. This 45-minute session, “Gasoline Direct Injection: Total System Diagnostics ” will be an engaging, interactive session with experts from Carter Engineered Fuel Pumps, that will teach you how to diagnose the entire fuel system of a GDI vehicle.

Modern gasoline direct injection (GDI) engines have two fuel pump opportunities. You still have an electric pump in the tank, but a high-pressure fuel pump is on the engine. These two pumps work in unison, so the correct quantity of fuel is injected directly into the cylinder. If either pump can’t generate the pressure or volume commanded by the engine management system, it will cause driveability issues. In a 45-minute webinar, the experts from Carter Engineered Fuel Pumps will train you on how to diagnose the entire fuel system of a GDI vehicle.

“Customers may understand that their cars have fuel injection, but they don’t usually know what that means,” explains Andrew Markel, Director of Content for Babcox Media’s Tech Group. “We’ll explain today’s systems so that professionals (technicians and service advisors) as well as consumers understand the complexities of these components.”

Topics to be Covered

  • Electric fuel pump voltage drop testing.
  • Measuring pulse-width signals with scopes, meters and scan tools.
  • Pressure testing for the high- and low-sides of the fuel system.
  • Using scan tool data to evaluate the health of the pumps and injectors.
  • High-pressure fuel pump visual inspection.
  • Diagnosing fuel-related stumbles and hesitation complaints.
  • Common DTCs caused by a compromised low- or high-pressure fuel pump.
  • Curing fuel pump contamination issues.
  • Ethanol and GDI systems.

Joining Andrew will be Julio Ortego, Engineering Manager, Repair Products at Carter. He is the Engineering Manager at Repair Products. He is based in Mexico and works closely with the Product team in Rochester Hills. He focuses on managing fuel pumps, water pumps and lift supports for the aftermarket.

The 45-minute webinar will include a live Q&A session and a certificate of completion. In addition, as a thank you for attending, 50 randomly selected attendees will receive a $10 Amazon gift card.
