Owners of 2007 F-150s report serious fuel-system and related engine issues. The most dangerous: fuel pump control modules fail intermittently or completely, killing the engine without warning and cutting power to steering and brakes on the freeway. One owner had the module replaced twice (at 14,000 and 24,446 miles) at roughly $500 each. Another broke down on I-75; another experienced an engine compartment fire at 52,000 miles, traced to a fuel crossover line failure by the fire chief.
Fuel lines themselves leak or rupture—two holes found in one line at 18,200 miles, another leak at 155,000 miles. Fuel sending units fail, leaving the truck unable to start or with a fuel gauge stuck on empty. One owner paid $407 for a sending unit at 118,000 miles.
A driver control module electrical plug melted during a fuel pump repair, suggesting poor placement or design. One owner reported unintended acceleration three times over three years, culminating in a collision with a building. Coil pack failures on the 4.6L V8 have blown spark plugs out of the cylinder head, requiring costly head repair.
Cold-climate owners note that repairs should not be necessary this early in the vehicle's life.
Failure modes owners describe
Fuel Pump Control Module Failure
The fuel pump control module fails intermittently or completely, cutting fuel supply to the engine and causing the truck to stall without warning. Loss of engine power results in loss of power steering and brake assist, creating a dangerous situation especially at highway speeds.
When: First failure around 14,000 miles; second replacement at 24,446 miles. Also reported on freeway; one case at 52,000 miles with engine fire.
Symptoms owners cite: Engine stalls suddenly while driving; Loss of power steering assist; Loss of brake assist; Engine will not restart or restarts after intermittent stalling; Multiple module failures on same vehicle
Codes mentioned: Fuel pump control module electrical failure
Repairs/costs cited: Fuel pump control module replacement; cost approximately $500 per replacement. One case also involved replacing driver control module and electrical plug that began to smoke and melt; repair cost $350–$421.
Recalls/TSBs owners mention: No recalls or TSBs mentioned; one owner noted vehicle not included in NHTSA campaign 07V278000.
Fuel Line Leaks and Rupture
Fuel lines develop leaks or rupture, creating fuel odor inside and outside the vehicle and risk of fire. One case involved two holes in the fuel line; another involved fuel crossover line failure that resulted in engine compartment fire.
When: 18,200 miles; 55,287 miles; 52,000 miles (fire case); 155,000 miles.
Symptoms owners cite: Strong fuel odor inside and outside vehicle; Fuel leak visible, especially after refueling; Engine compartment fire; Check engine light illuminated intermittently (one case)
Codes mentioned: Fuel system leak, Fuel crossover line failure
Repairs/costs cited: Fuel line replacement. In fire case, fuel crossover line was identified as failure point by fire chief investigator.
Recalls/TSBs owners mention: One owner referred to NHTSA campaign 07V278000 (Fuel System, Gasoline); another vehicle stated it was not included in that campaign.
Fuel Sending Unit Failure
Fuel sending unit fails, preventing engine start and causing incorrect fuel gauge reading.
When: Not specified in narratives; one case at 118,000 miles.
Symptoms owners cite: Vehicle will not start; turns over but will not fire; Fuel gauge reads empty when tank is full
Codes mentioned: Fuel sending unit failure
Repairs/costs cited: Fuel sending unit replacement; cost $407.
Driver Control Module Electrical Failure
Electrical plug to driver control module smokes and melts during operation, indicating a short or overload condition.
When: During fuel system repair on vehicle with blown #9 fuel pump fuse.
Symptoms owners cite: Electrical plug to driver control module smokes and melts; Vehicle runs only briefly after initial repair before electrical failure
Codes mentioned: Fuel pump fuse blown, Driver control module electrical fault
Repairs/costs cited: Driver control module and electrical plug replaced. Owner noted poor placement of control module (reportedly near fuel tank rather than near fuse box or firewall).
Fuel Pump Assembly Plastic Degradation
Inferior plastic on fuel pump assembly develops cracks or leaks, allowing fuel vapor to escape.
When: Not specified.
Symptoms owners cite: Fuel vapor leak from fuel pump assembly
Unintended Acceleration
Truck accelerates forward when shifted into Drive despite driver's foot being on the brake. Owner alleges this happened multiple times over several years on the same vehicle.
When: First incident about 1 year before initial complaint; second incident 3 months later; third incident April 12, 2009 with 14,454 miles on truck.
Symptoms owners cite: Vehicle accelerates forward when shifted into Drive; Brake pedal depressed but truck still accelerates; Multiple occurrences on same vehicle
Repairs/costs cited: No repairs mentioned; owner filed complaint after third incident resulted in collision with building.
Coil Pack Failure with Cylinder Head Damage
Coil pack fails and blows spark plug out of cylinder head on 4.6L V8, requiring both coil pack replacement and cylinder head repair kit.
When: Two occurrences within 3 months; vehicle had no specified mileage.
Symptoms owners cite: Engine shuts off and will not restart; Loss of engine power while driving on highway; No power steering
Codes mentioned: Coil pack failure, cylinder #3
Repairs/costs cited: Coil pack replacement; cylinder head repair kit to fix stripped threads from blown spark plug.
