Why? Because my ST has 59,900 miles on it! For those who have forgotten, powertrain warranty is 60k miles.
Did you have a tune on yours? If so, did you return to stock before visiting the dealer?I'm fighting ford about the same problem with my 13 st. i just replaced it myself for $600, plus a weekend. had 26k miles on it.
Was it just a hose?Did you have a tune on yours? If so, did you return to stock before visiting the dealer?
Mine is back at the dealer again. Turbo lost boost again after about ten miles. Hopefully just a hose they didn't tighten properly. It wasn't smoking this time, so I hope that's all it is.
I haven't picked it up yet but dealer says it was the high-pressure fuel pump! Huh? Doesn't make sense as it ran fine except for no boost... unless the computer shuts the boost down if the hpfp fails perhaps? And why would the fuel pump go out within ten miles after replacing the turbo? Dunno... but they fixed it free of charge, so I can't complain.Was it just a hose?
The HPFP is electromechanical. The electric components of the pump assembly include a solenoid that controls fuel flow into the pump assembly. The mechanical components of the pump include a cam-driven piston that pressurizes the fuel, and a bypass valve that sets maximum pressure.isn't the hpfp mechanical?
