Won't Start

[AirRescueScott]

Well I went to pick up my daughter from school, shut down the motor (which had been running for at least 30 min). Went to start and engine just cranked and cranked like it was getting no fuel. I do hear the fuel pump running from frame rail, it did seem like the engine was developing more "diesel sound" before, but I could be just hyper sensitive. No check engine lights, no nothing. It will start, just takes many attempts. I've got 4900 miles on it. Anyone else had this problem, or suggestions? I made an appointment with dealership for morning. You spend $63k on a truck one would think they would have loaners while your vehicle is in shop, but not here. Good thing I haven't filled out my survey from ford yet.....grrrrr

Sound like a leak in the fuel system that's sucking air. Get the same problem if you don't tighten the frame mounted filter all the way. Hope it's simple, keep us updated.

Well called the dealership and they said there was no "error code" so they were trouble shooting still. I mentioned that in the past there was problems with air getting in the fuel lines of these trucks, so might want to check that. I get a call later saying they think the low pressure pump is sucking air and have to order a new one. WTH?!?!
They said it's ok to drive, just may take multiple attempts to start and I'm to bring it back monday for the new part installation. The truck runs rough, clatters like the old ones did now, and obviously isn't right. Will catastrophic failures (ie- rod, valves, etc) be picked up by a computer? Could the low pressure pump sucking air be the culprit of this problem by itself?
They are getting too dependent on what the computer tells them, and not using critical thinking skills. In my field we call it "treat the patient, not the machine"......grrrr

I'd say the pump is your only problem. It's the frame mounted DFCM. May have a faulty one or it may be leaking past the gasket. It doesn't sound like you have experienced any kind of catastrophic failure like your talking about. These trucks have so many redundant monitoring systems that it would throw a CEL if you had a serious problem. Glad to hear I hit the nail on the head with air in fuel problem. Keep us updated.

Have you checked the fuel filters yourself? Might be very simple.

Well after a week in the shop, fuel pump changed and all fuel lines changed. We found out the problem, diesel fuel mixed with gas. No f'n clue how that happened, as I'm anal about making sure I double check to see I've grabbed the right nozzle. The thing is my truck has been in the shop for a week, and I know I put half a tank to top it off the last time I filled up. I usually use one of two stations, station one says they've gotten no complaints. I've not had a chance to ask station two.
The truck runs and actually runs well unless it's at low speeds and under some torque. They said they were NOT going to send the filter or pump to ford, they said ford will immediately void all my warranty if found out. I'm hoping they hold true to this...
Anyone else have any experience in mixed fuel in these new trucks?

You should be OK as long as they drain tank and fill with diesel. We did that to a Duramax and it made it until we traded it in at 200k or so.

I would dig into where you got the mixed fuel at. I keep every receipt for fuel just in case something like this happens. We got to fuel stations and trust that everything is above board with their operation, when it's not, you need to have some proof that the bad fuel came from them.
