P0313 - Misfire Detected With Low Fuel

The ECM detected a misfire while fuel level was low enough to affect pickup or fuel delivery.

Treat the code as the starting point: compare symptoms, likely causes, and repair paths before pricing parts or moving into an estimate.

Code Overview

The ECM detected a misfire while fuel level was low enough to affect pickup or fuel delivery.

Common Causes

• Low fuel level
• Fuel pickup problem
• Weak fuel pump under low-tank conditions

Diagnostic Steps

1. Confirm the fuel level
2. Check for fuel delivery issues
3. Inspect for additional cylinder-specific misfire codes

Likely Repairs & Cost Guides

Use symptoms, scan data, and quick checks to confirm the likely repair path before pricing parts. The estimator helps compare repair paths before replacing anything unnecessarily.

Related OBD Codes

Browse nearby code-family pages when the same fault pattern overlaps across systems, such as misfire, lean fuel trim, EVAP sealing, cooling, or charging faults.

Next Steps

Move from code lookup to diagnosis, then estimate the likely repair only after symptoms, causes, and checks point to the same path.
