2014 F150 pulling boat thru Montsna just lost power on

Customer Question

2014 F150 pulling boat thru Montsna just lost power on freeway. Waiting for tow. Why would new truck suddenly lose power? Oil just changed, no oil lights on, not overheated

Is this a 2013 or 2014, you have listed both?

Also, what engine does the F150 have and did you loose throttle response where you had no engine RPM when you stepped on the gas, or...?

Customer: replied 2 years ago.
2014 not sure engine type. Revs to good RPM then just progressively drops RPM then sputters and engine actually stops
Expert:  A. Penland replied 2 years ago.

Does it restart ok?

Customer: replied 2 years ago.
Starts, then I can briefly rev to good RPM, then RPM drops til it sputters and dies

How many miles on the truck?

Customer: replied 2 years ago.
20,943. Found engine type: 5.0 liter V8 FFV
Expert:  A. Penland replied 2 years ago.

The 5.0L we have not seen many problems with because Ford also uses that engine in the Mustang GT.
The problem could be a sensor issue or a fuel pump issue (low fuel pressure). We have seen a few problems with the fuel level sensor. You may want to make sure there is fuel in the fuel tank.

Tank filled 50 miles ago. Shows 7/8 full. Anything I can do to remedy on the roadside?
Expert:  A. Penland replied 2 years ago.

Not really. Todays vehicles you need a code reader or scan tool to check for trouble codes in the modules to properly find the problem.

Why would a fuel pump fail at 20,000 miles?
Expert:  A. Penland replied 2 years ago.

It is just an electrical motor inside the fuel tank. Electrical parts are prone to failing. We have had brand new vehicles have the electronic power steering rack and pinions lock up to where you cannot steer the vehicle and we have to replace the rack and pinion. I just mentioned the fuel pump, but we have had problems with the sending units on the fuel pump for the fuel level short out. But you just filled up the tank, so that can be eliminated. We have also had the vapor management valves stick open pulling fuel vapors to the engine causing lack of power. You can disconnect that hose to it and have someone start the engine and plug the port on the sensor and see if it will run. It is located on top of the intake manifold next to the throttle body. See the picture below.

Average repair cost if fuel pump?
Expert:  A. Penland replied 2 years ago.

With your truck having 20,000, and it being a 2014, it will still be under warranty and the tow to the dealership will be covered also.

Thanks
