Low Pressure Fuel System Pressure - Too Low
What it means
P008A means the low-pressure side of the fuel system isn't reaching the pressure the engine needs. Starved of fuel, the engine can lose power, run lean, hesitate, stall, or fail to start. Because it can leave you stranded and stress the engine, it's worth diagnosing right away.
Can I keep driving? Drive as little as possible — low fuel pressure can cause power loss, stalling, and hard starting, and running lean can stress the engine.
Real-world scan data
Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle.

Common symptoms
What you'll notice
- Check-engine light on
- Power loss or hesitation, especially under load
- Engine runs lean or rich, sometimes surging
- Stalling or hard starting
- Engine may not start if pressure is very low
Common causes
Most likely first
- Low fuel level or ran out of fuel before the code setLikely
- Weak or failing fuel pump or fuel pump controlCommon
- Clogged fuel filter or restricted/kinked fuel lineCommon
- Faulty low-side fuel pressure sensorLess often
- Wiring or connection problems at the fuel pumpLess often
How to diagnose & fix
Work through it in order
- Confirm there is adequate fuel in the tank.
- Attach a mechanical gauge to the fuel rail and compare actual pressure to the sensor's reported value.
- Test the fuel pump for proper power and ground at its harness; check for excessive resistance or loose connections.
- Inspect the fuel filter and lines for restriction, kinks, or damage.
- Replace the failed component — pump, filter, sensor, or wiring — then clear and re-test.
