Fuel Delivery Error

Descripción

This code indicates a problem with the fuel system not delivering the correct amount of fuel to the engine. This can cause the engine to run poorly or even stall.

Pasos de reparación

1. 1 Check the fuel pump relay by swapping it with an identical relay in the fuse box and see if the issue resolves.
2. 2 Inspect the fuel filter for clogs or restrictions and replace it if it has not been changed according to the maintenance schedule.
3. 3 Check fuel pressure using a fuel pressure gauge at the fuel rail; compare readings to manufacturer specifications at idle and under load.
4. 4 Inspect fuel injectors for signs of leaking, fouling, or poor spray pattern by performing a fuel injector balance test.
5. 5 Test the fuel pump by listening for consistent humming when the key is turned to the ON position; measure voltage and amperage draw at the pump connector.
6. 6 Replace the fuel pressure regulator if fuel pressure is out of specification or if vacuum line to the regulator shows fuel contamination.
7. 7 Replace the fuel pump if pressure and volume tests indicate weak or inconsistent output.
8. 8 Replace leaking or malfunctioning fuel injectors if injector balance testing confirms a faulty unit.
