P0230: Fuel Pump Primary Circuit Malfunction
Can you still drive? Only if the engine runs. If the engine stalls or will not start, the vehicle must be towed. Driving with an intermittent fuel pump can leave you stranded.
What Does P0230 Mean?
Code P0230 indicates a malfunction in the fuel pump primary control circuit, which includes the relay, wiring, and fuse that supply power to the fuel pump. The ECM monitors this circuit and sets P0230 when it detects an open, short, or unexpected voltage level. Without a properly functioning fuel pump circuit, the engine may not start or may stall while driving.

1 Active Recall — 2026 Ford F-150
The following NHTSA safety recalls have been issued for this vehicle. Contact your dealer to check if your vehicle is affected.
ELECTRICAL SYSTEM: INTEGRATED TRAILER BRAKE CONTROL
Ford Motor Company (Ford) is recalling certain 2021-2026 F-150, 2022-2026 F-250 SD, F-350 SD, F-450 SD, F-550 SD, Maverick, 2024-2026 Ranger, 2023-2026 F-600 SD, 2022-2027 Lincoln Navigator, Expedition, and 2026 E-Transit vehicles. When towing a trailer, the integrated trailer module (ITRM) may lose communication with the vehicle, possibly causing a loss of brake and turn signal lights, or a loss of brake function. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, " Lamps, Reflective Devices, and Associated Equipment."
Remedy: The integrated trailer module software will be updated by a dealer, or through an over-the-air (OTA) update, free of charge. Owner notification letters are expected to be mailed March 17, 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 26C10. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning March 17, 2026.

Frequently Asked Questions
How do I know if my fuel pump relay is bad?
Swap the fuel pump relay with another identical relay in the fuse box (such as the horn relay). If the fuel pump works with the swapped relay, the original relay is faulty.
Why does my car crank but not start?
If you have P0230, the fuel pump is likely not receiving power. Check the fuel pump fuse first, then the relay, then the wiring to the pump. No fuel pressure means the engine will crank but not fire.
