3. Step-by-Step DIY Repair Guide for Chevrolet Malibu
Connect an OBD-II scan tool and inspect live Mode $01 telemetry for Fuel Rail Pressure (FRP). Compare actual pressure against the ECU's desired setpoint during idle and 2,500 RPM revs. on the Chevrolet Malibu equipped with 1.5L Turbo 4-Cyl (163HP) / 2.0L Turbo (227HP).
Verify the low-pressure lift pump is delivering 55–75 PSI to the HPFP using a mechanical fuel pressure gauge on the Schrader valve. on the Chevrolet Malibu equipped with 1.5L Turbo 4-Cyl (163HP) / 2.0L Turbo (227HP).
