P0230 on Alfa Romeo by model: symptoms, diagnosis and fix
2017+ Giulias can experience sudden engine stall or no-start due to a defective low-pressure fuel pump inside the fuel delivery module. The pump's internal commutator wears prematurely and loses contact, cutting fuel supply at any speed. NHTSA recall 25V-586 (Stellantis campaign 93C) covers free replacement. Symptoms include stalling at idle, no-start hot, and intermittent fuel pump prime noise from the rear of the vehicle. Failures cluster at 30,000-80,000 miles.
Common Symptoms
- Engine stalls while driving
- No-start condition
- Multiple warning lights
- Loss of electrical power
How to Fix
Have the ECM and wiring harness inspected at an Alfa Romeo dealer. FCA has issued TSB 18-024-17 REV.A addressing the wiring harness routing. ECM replacement with updated software may be required.

2018+ Stelvios can experience sudden engine stall or no-start due to a defective low-pressure fuel pump inside the fuel delivery module — same defect as the Giulia, same supplier, same NHTSA timeline. The pump's internal commutator wears prematurely and loses contact, cutting fuel supply at any speed. NHTSA recall 25V-667 (Stellantis campaign 93C) covers free replacement. Failures cluster at 30,000-80,000 miles; stalls reported at highway speed make this safety-critical until repaired.
Common Symptoms
- Engine stalls at speed
- Intermittent no-start
- Dashboard warning light cluster
- Power loss while driving
How to Fix
Inspect and repair the ECM harness per FCA TSB 18-024-17 REV.A. Clean and reseal all engine bay ground points. ECM replacement with updated calibration may be needed for persistent cases.

Frequently asked questions
What does P0230 mean on a Alfa Romeo?
P0230 stands for "Fuel Pump Primary Circuit Malfunction." P0230 means the engine computer detected a fault in the fuel pump primary circuit — the control side that switches the fuel pump (or its relay) on and off. The PCM energizes this circuit to run the electric fuel pump that delivers fuel to the engine; if it sees voltage that is too high, too low, or out of expected range, it sets this code. Because the pump may not run correctly, the engine can crank without starting, stall, lose power, or hesitate. This is a circuit/control fault rather than a direct measurement of fuel pressure. On Alfa Romeo it is documented across 2 models: Giulia, Stelvio.
What are the most common causes of P0230?
The most common causes of P0230 are: Faulty fuel pump relay, Damaged wiring or connectors in the fuel pump control circuit, Corroded or loose ground/power connection, Failed fuel pump or fuel pump driver module, Blown fuse or fusible link, Open or short in the primary control wiring, Faulty PCM driver output (rare). The specific cause varies by vehicle.
How much does it cost to fix P0230 on a Alfa Romeo?
Published repair estimates on Alfa Romeo range from $200 to $2,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
