P0087 Fuel rail pressure low limp under acceleration

Guys,


Getting the P0087 - Fuel Rail Pressure Too Low.

It happens under heavy acceleration.(Like being on the on-ramp of the freeway). if i keep a light foot. Code never comes up. Went a week no problems.

Any ideas on what causes this. Truck as been at dealer for 3 days now. They are still diagnosing. They even went ahead and changed the filter again and still getting the code.

The dealer is reputable and even has its own diesel department. So i don't think they are clueless.

Truck has 50k Miles. Fuel filter changed at dealer every 10k miles. Only use good diesel at places with a big turn over rate.

P0078/low engine power

I have exact same problem with my 14 6.7. It is in dealer shop right now for 4th time. Last time they changed the pump in the tank, still same problem occurred. They are looking at the sensor that reports this condition and the computer that reads it.
will post if they get it fixed

Dealer called back on truck.
Ford recommends complete fuel system replace to cure problem 18 hr job, fortunately it is still under factory warranty.

You have no idea how lucky you are... Usually Ford screws people when the hpfp needs to be replaced. I hope for your sake they don't find rust and send pics/parts to Ford.

They said they checked for that and found no rust or contamination. Truck only has 24k on it should have no rust at that age.
