Took my 2010 6.4 with 90,000 miles into the dealer today. I've been having intermittent cold start issues which I linked to a dead passenger side battery which both are only about a year or so old. Decided to have them change the fuel filters while I was there... The dealer didn't purge the air properly and now they can't start it. One lube tech said he thinks the HPFP is going out. The tech that performed the work said fuel bowels were spotless.

1. Could his preliminary diagnosis be accurate?

2. Truck ran fine when I brought it in, if something, such as the HPFP failed while they were working in it, what's the recommended action? Should the dealer be held accountable? Could air in the system have caused a failure? Is there anything the tech could have done to cause a major failure immediately?

They said there aren't any codes, but they are lube tech's so I don't know the real story. I won't know any more info until Monday at the earliest.

Not relevant, but may be a sign of the lake of knowledge by the techs: he told me this is the second one this week with problems immediately after fuel filters. The last one, the had to replace the whole HFCM.

 

There's a tool that bleeds the fuel system. It has a banjo bolt with a clear plastic tube that screws into the fuel cooler (high pressure return side). Thats all that needs to be done.

 

You absolutely have to bleed the air out of the fuel system after fuel filter replacement or the engine will not start. Numerous posts here to review about it.

Don't let them change anything until someone who knows what they are doing does so. And then find another dealer and never go back to the unknowing lube techs again.

Second question, if the truck was running when you drove it in and they broke something then they are on the hook to make it right for you.

 

I tried asking them what steps they took and they said they did all that. They seemed REALLY frustrated as if something serious was wrong and they were on the book for it.

 

The good news.... I have a 2014 Platinum to drive until they figure it out.

 

fuel bleed tool along with just checking the fuel cutoff switch behind the dash panel to see if it is tripped. Open passenger door, side of the dash is the access panel.

Thanks Scott... I do know a lot of this stuff. I'm trying to see if there's anything I missed.

They had the bleeder on the truck when I was asking a ton of questions pissing them off.

I asked them about the fuel cutoff.... They knew nothing about it. I had to show them. Wasn't tripped.

They put in a second set of filters. (Probably allowing MORE air)

 

so...what codes are they getting? If they have fuel and the bowl has fuel...then scan for codes time.

 

They say no codes...

They said they get the engine light a few times after it started and stalled along with the Wrench symbol a few times.

So I don't believe they even checked the codes.

The service was being done at the QuickLane. The main service center was closing when I pulled up.

 

Re-purge for air in the fuel lines. Key on, key off for additional 6 times.

Put the batteries on the charger.

Let the fuel pump run till it shuts off. Then key off. Then back on till the pump quits.

Have then listen to the pump and it's gurgling. That is air.

 

fyi...........

 

Thanks... It's on the dealer's hands.... If I had done it, I'm sure it all would have been fine. It's just so much more convenient not having to lay down in the driveway.

 

It's both aggravating and scary to take your truck in to a shop who, by their very association with Ford, should know how to do these things. What's aggravating is most of the time they just don't care. Or they are pushed for time. Sometimes they just absolutely don't know how to properly perform the task and they just try and wing it. I've had several issues with my local dealer that caused me to switch to another one, 35 miles from me, and then I had issues with THAT ONE. It's ridiculous. I hope you get things worked out. Make them take care of it. You drove it in; you should be able to drive it out with only paying for what you asked them to do. Nothing more.

 

Well said, since my first oil change from the dealer(truck came back overfull) I have not been back. It's sad because for the most part a with proper training these things can be done by lower paid individuals and not tech's.
Needless to say I do my own work on my truck.

 

One of the things to do is find a Ford dealer that has Diesel techs....not all do. All Ford dealers will do basic servicing though.

I'll go the extra mile and ask to talk to the diesel tech and see if he has any of the accredited ford diesel training ....these trucks cost way to much to service so having it done properly is paramount.
