MIL Flashing, P0087, P0301, rough idle, hesitation, fuel smell.

Only because of the P0087 code that I am worried about the FPCM.  That will leave you stranded eventually, but again, first check the connector at the FPCM.  Just may need cleaning & "lubing" with dielectric grease.

It's a bit of work to get at the injector, but I thought I posted the steps somewhere ...

Not sure exactly which PIDs are available in TPro for DI engines (I do not have access to one).  I am sure FoMoCo or EcoBoostSHO would know for sure.  Try the FPD and FPA and see what numbers it gives you, not sure if that pulls the LPFP or HPFP numbers.  Also Fuel Pump Duty Cycle if you see it.  Injector Fault, it may help it may not.

Also get familiar with the Motorcraft OBD Manual for 2014, it will show you the various threshholds the PCM (stock) looks at to make decisions about codes.

Off the top of my head...

Desired HPFP pressure
Actual Fuel Rail Pressure
HPFP rail pressure sensor voltage
LPFP Pressure
LPFP duty cycle
LPFP sensor voltage

I think the only way to see injector info is DMRs which Torque (and sct) do not support, anything listed in torque doesn't work, at least for me.
 
I'm going to check this when I get home from work. Is this unit located under the rear seats? Accessible from the inside? I've done a bit of search and Googling and I can't find a definitive answer, except it's location on a F-150. The diagrams on Ford Parts, eBay, and Tasca aren't brilliant.

I've ordered a few parts and have them in route. If I don't need them, at least I've got spares of things that commonly fail. I'm well under the cost of a trip to the dealer, so as long as it doesn't turn out to be something like a cracked piston, I'm in good shape. LOL.

Thanks!

Found the FPCM, connector looked good and clean, reseated it, still have same issue. I've got an FPCM, an LPFP, injector, and fuel rail o-ring set on the way. All together the parts cost less than a trip to the dealer, even after I throw a set of plugs and an oil change at it. Even if they're not all broke I'll have good parts on hand in the event of a future failure.

While playing around with Torque Pro this afternoon monitoring the items suggested, the car did start to puff out some significant white smoke (but it died down). I was initially very concerned as the symptoms initially onset as soon as I throttled up to pass someone on the highway, but the smoke smells like pure fuel and after some quick searching on the forums, it appears that's fairly indicative of an injector. Racingmason23, Tomc612, and FO SHO all had the exact same issue it seems. Here's to hoping it's a simple repair.

Thanks everyone for the help, I'll post up once the parts arrive and I can mess with it. I'll probably swap the FPCM first and see where that takes me, but I think injector is second on my list and my likely culprit.

Here's a quick video of Torque Pro with the car idling while misfiring today, the smoke died down almost completely by the time I took this.

I think the best course of action is to stop screwing with it before I damage something and wait for my bits to arrive. Hopefully in time for the weekend.

Again, thanks for all the help from everyone. Definitely makes this less stressful.
 
If you can, add trims to that screen so we can see those too while it smokes. Saw some pretty low pressure on the HPFP and I'm wondering if that's when an injector is sticking open and trying to compensate. If it's an injector, we should be able to narrow down the bank with the trims.
 
I can do that tomorrow. Need both long and short term, or just short term?

Both please.

You can never have too much data....
 
My kinda answer! I've got a new screen setup in my Torque Pro phone with all the data, I'll try to give it a go in the morning, if not I'll definitely do it at lunch time and post another video. Thanks!

Is there a preferred diag tool besides Torque Pro? I've got manufacturer specific for the other cars (Techstream for the Toyota, VAG-COM for the VW) and wouldn't mind picking up something for the Ford if there's something out there.

The last couple days have been crazy, just getting around to posting the requested videos.

This video was taken after 24hrs of sitting, cold start, and I let it idle until I heard some noises in the back. Turns out it was just some tools I Had on the back seat from removing the FPCM and checking that slid off. Was just a metal on metal noise so I shut things down instantly. Haha.

I took this video right after the restart, but my camera locked up in the middle of it. Not really sure if it's useful or not.

...and for whatever reason, I took a third video, while the car was still idling from the 2nd video and let it run a bit.

I've got an injector, o-ring kit, FPCM, and LPFP on the way. Hopefully one or all of those fixes it. Unless it's something terrible and I need a bottom end. :/

Thanks!
 
Looks like it was pulling lots of fuel and I assume when the cel came on it went to a limp home map which is why you had no trim data.

Great document. On iPhone it just opens in a new browser window and then I saved it to iBooks which synced it automatically to all of my devices... Back to the OPs problem...
 
I do have it, thanks. Someone linked me to it earlier and I searched around in it for the P0087 and the P00C6 seem to point to the HPFP or LPFP typically, but the low rail pressure could be caused by an injector stuck open. Not super clear on how I can determine if an injector is stuck open without just changing it an seeing what happens.

From what I can determine by reading the linked document is the P0087 and P00C6 codes are indicated of insufficient feed pressure to the fuel rail, and the sensors involved are the FLI (fuel level input), FRP (fuel rail pressure), FVR (fuel volume regulator, solenoid on HPFP), and Lift Pump (LPFP). I'm still leaning toward injector as my problem is a single cylinder and I've found three other forum references to the same symptoms and injector was at fault. I think a stuck open injector is plausible to cause low rail pressure if the fault is extreme enough.

The parts I ordered (injector, LPFP, and FPCM) will all be here Wednesday. I'll try swapping the FPCM first, but if that doesn't do the trick I think the injector on cylinder #1 is my next best guess in terms of throwing pars at it. If all three of those parts don't fix it, I suspect a compress test is in order before ordering a HPFP.

Any insight is openly welcomed. Thanks to everyone in this thread. I couldn't have asked for a better welcome to the EBPF community.

Ugh. Parts delayed a day. UPS truck had "mechanical difficulties" which caused the delay. Don't worry, the irony is not lost on me. Hopefully this weekend I can get her back on the road. Moved it around back today to have a good place to work on it, startup is unchanged with the white smoke and misfire and a SUPER strong smell of fuel. I keep checking under the car for a Niagara Falls of fuel coming out. LOL.

Hopefully this weekend I can dig into it more. Thanks again to everyone for the help, here's to some progress on this long holiday weekend.
 
UPS delivered. So far, it's NOT the FPCM. Swapped it, problem persists. Dinner and then on to the next likely item, which I'm taking a stab at the injector next, unless someone thinks something else should be tried first.
 
no easy fix :(  better be the injector ...  take pics of the removal/install if you dont mind.  Noones documented yet.
