Title : SPN 3055 FMI 1 No Start due to Low Fuel Rail Pressure Troubleshooting
Applies To : EPA 2010 MaxxForce 11 / 13 and N13 Engines
CHANGE LOG:
2015/02/26 - Added note about retiring article due to inclusion of information in the Fault
Code Action Plan.
7/07/14 Added step 1. Added note at step 12 for where to find information on KUEV. Added
Fuel Filter SRT.
5/19/14 Eliminated fuel dead head test.
4/10/2014 - Added a NOTE under 'Fault Overview', changed Drive Cycle under 'Drive Cycle to
Note: All information is now in the appropriate Fault Code Action
Plan. This iKNow article is set to retirerefer to the Fault Code
Action Plan, going forward.
FAULT OVERVIEW:
SPN 3055 FMI 1 ‐ Low Fuel Pressure at Start:
Condition / Description
Setting Criteria

• Ambient Pressure > 12 psi (83 kPa)
• Ambient Temp > 19 F (‐7.04 C) Battery
Voltage (before crank) > 11 Volts
• Fault code sets when the Engine Control Module (ECM) detects Fuel Rail Pressure (FRP) does not build within a
predetermined time while the engine is cranking.
• NOTE: If the fuel filter was replaced right before the 3055‐1 fault set, this is common and does NOT require
diagnostics. Clear the fault and run the engine to purge air from the system. Then shut off and restart the unit to
verify that code does not return. If the fault does not return, no further repair is needed.
Malfunction Indicator Lamp (MIL) Reaction:
• MIL will illuminate when this fault is detected (one trip MIL).
Associated Faults:
• SPN 94 FMI 0 (FDP)
• SPN 157 FMI 3, 4, 20, and 21 (FRP)
• SPN 633 FMI 3, 4, and 5 (FPCV)
