What Is Prime Fuel Pump and Does the YOUCANIC Scanner Support It?

The Prime Fuel Pump function commands the fuel pump to run, pressurizing the fuel system and removing trapped air. This is essential after certain service procedures to avoid hard starts or no-start conditions.

When You Need It

• After fuel filter replacement (especially on diesel engines)
• After fuel injector replacement or service
• After running the fuel tank dry
• After fuel line or fuel rail repair

What the Scanner Does

The scanner commands the fuel pump to run for a set duration, building pressure and purging air from the lines. On diesel vehicles, this prevents extended cranking and potential injector damage from air in the system.

Is My Vehicle Supported?

Fuel pump priming is supported on many diesel and gasoline vehicles. Verify at coverage.youcanic.com or email support@youcanic.com with your VIN.
