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.

How often have you changed your fuel filters?

Had this happen on my 2010, didn'ttchange the filters for 20k, so the HPFP pretty much died. Truck was just out of warranty and $850 later for a new fuel pump it was fine.

Filters changed every 10k and water sep drained monthly, have never seen any water in what was drained. Dealer said everything is clean and it will be covered on warranty.

For some reason the HPFP will start making metal somewhere between 30000 and 50000 miles. It will send tiny particles of metal from the gears forward through the fuel system causing that code. Ford will try to blame it on not changing the fuel filters or not using, "quality fuel". But when there is metal forward of the pump and none from the tank to the pump that is a clue. You should make sure and pressure the tech. to look further if they try to blow you off. It has been my experience they will take the easy way out every time. The protocol for that code is to check the filters. If the filter has discoloration that is where they stop. They will tell you about the filter, replace it then run the engine. If the code does not promptly come back that is where they stop. They will send you on your way. The pump is slowly coming apart in the meantime.

Thanks for all the info on the HPFP.
I am picking up the truck from the dealer today. Was told that Ford now has a kit for this problem it replaces every part in the fuel system including injectors all the way back to the tank pump. I think they are shotgunning the problem, but if Ford has developed a specific kit for this issue then there are many more out there that have this problem or will have it. My truck only has 24K on it.

Ford developed a kit for simplicity. Dealer orders 1 part number and gets what is needed instead of 15 separate parts.

It is not some magical fix, just an oem replacement kit with all parts needed.
