Title: rough idle no accel response and P0087 code
Post by: lamrith on July 13, 2019, 05:49:36 PM
Title pretty much sums it up, wife was driving today and the car died on her.  She said it stopped respond to pedal and then died.  Thankfully she coasted to side of road safely.  I had her try pull codes and it gave her none.  I ran out there hit starter and took long time to start then idled rough.  I pulled codes and P0087.  Not sure if it could be related, but I had a P0627 code pop up randomly 2 months ago, then it popped up a week after than and nothing since.  Only code now is P0087.

Quick search here and it seems that might be a TSB related to P0087, but also chances it is;

Since I am tuned I am doubting a reflash of factory updated tune per the TSB is going to fix it?  It is probably "mechanical" (failed hardware) in some way?

Is there a way to diagnose if it is the fuel pump/module vs a bad injector?  We have had a few bad injectors on board in the last year and my biggest concern is nuking the motor from hydrolock.  I have no problem doing a fuel pump myself, but if I take it to a dealer to have them run thru it to diagnose it then I am really stuck with them and at their mercy and I am not a fan of that for something I can diagnose and fix myself.

It sounds like it's your Fuel pump control module!  Recall performed!

Is there by chance a way to lookup online if that recall has been done on my car?

Since it is so easy to get to, take a pic of what you got.  Dunno if it will have a production date stamp on it, but replacing it yourself is super easy.

Plugs are all dry.  How long would it take for them to be dry if I had bad injector??  It has been a few hours since the car last ran.
My concern is bad injector and hydrolock.  Injector replacement is out of my wheelhouse.  Pumps and relays I can do here at home..

Part of my concern is that the P0087 code for low pressure was because an injector was stuck open, and the fuel pump could not keep up which is why I keep bringing that concern up, maybe I am just overthinking it?  There was zero fuel smell out of any of the cylinders or from any of the injectors.

Mine does not, I have no fuel smell anyplace.  I will start with the relay module and go from there.

Those are NGK LTR7I-11 plug they are year and half old.  They have a tapered electrode and ground bar like that from the factory if you are thinking that is errosion.  There are no signs or erosion or degradation of the electrode or ground bar on eh ones I have pulled, they are still crisp and uniform in shape.
(https://static.summitracing.com/global/images/prod/large/NGK-6510_PT.jpg?rep=False)

But yes since the are out, I plan to replace them.  I will say the boot lubricant I used when I did the plugs a year ago has worked wonders.  the plugs AND boots slid right off with zero problems.  MUCH nicer than the 10rnd battle royal I had with the original ones.

Quick follow up.  I put plugs back in and put everything back together.  Got the Livewire display reconfigured so I could see rail pressure.  Pretty sure the LPFP or Module is bad.  Could not get over 11psi fuel pressure, that tells me the HPFP is not getting anything as I bet the LPFP puts out more than 11psi if it is working.

Hard to say if either was replaced or simply passed inspection.  Time to get eyes on the control module.

I zoomed in on this as I could tell there was some sort of engraving there, but it is super faint.

Then I noticed the blemish, it is hard to tell, but zoomed in that mark on top right looks like it got hot?  melted from inside?  I thought maybe a mold mark but is an odd shape/location for that.

Contacting dealer in morning to see how much they want for a module.  Rockauto has it, but to get it quick then is $$ for shipping.

Replacement part number:

Try scanning the bar code, may be some useful info there.  What is the build date on your SHO?

Scanning did not turn up anything.

Per that last  pdf I need to change it.

No idea build date on the car other than it is a 2013 my, pretty sure purchased by original owner oct/nov of 2012.  Where can I find build date?

Thanks Z!  Interesting that mine does not have the code per SHOdded document, yet is older and looks like your old one.  I also noticed that both of yours have the casting mark in the same place as mine so it did not burn up or anything, just failed.

Crossing fingers that dealer has one nearby to have in a day or two.

Finally got in touch with dealer this morning.  They do nto have the module in stock but can have it tomorrow.  Bit more $ than RockAuto, BUT have it tomorrow, and Rock auto I would have to hope they ship today and then pay air freight.  So I bit bullet and had dealer bring it in. 

Crossing fingers the beast is back roaring tomorrow night.

Isn't the module covered by the recall? When I heard of the module recall, I checked the ID on the module and mine was one that needed replacement. I didn't want to take the car in as I just installed a tune. So I ordered one from an online discount parts Ford dealer. They sent the one that was being recalled. They didn't have the replacement modules in stock yet. I sent it back and ordered from another online dealer. Same results. So I went to my local dealer and they had the correct replacement module in stock. Of course I had to pay retail. Then I received the recall notice and took it to that same local dealer and they reimbursed me the full price I paid for the module.

I have no recall notice and according to ford the recall has already been done on my car.  Car does not run at all, so towing to dealer cost 2x what it does for me to replace the part and I get my car running in 1/2 the time.  Just zero upside to having dealer involved in repairing it at this point.

Post by: Livernois Motorsports on July 15, 2019, 04:00:28 PM
One of our sales team members had a 2013 SHO PP with a similar situation a few years back.  He was driving to work one morning and his car shut down on him on the freeway losing all power and had to coast off to the shoulder.  Towed it into the local Ford dealer since he was already aware of the fuel pump module issues which they had sent a letter about previously.  They installed the module under warranty and took care of his issues.  So hopefully you just need that module and will be all set from there. 

He did however get the car back with a different strategy code for guys with tunes FYI.  So anyone going in for this service it's strongly suggested to return to the factory tune first, and then to check the ECU codes afterwards before trying to re-tune in case they've been changed while in the dealership.  Then if you get the car back with a new strategy code just send in a request with those new codes and we can get your tuner updated accordingly.

Thanks Livernois!  Yeah I had the car towed home so I could dig into it and swap out tune/MAP if needed to hit a dealer.  Not sure a dealer would replace it since my car shows it was already done?  IT is so simple though I will swap on my own and hope that is the failure item.

That is what I was thinking too, but then the pictures Z sent both of his had marks in the same location so maybe it is just a casting mark?

I really wish someone had a wiring diagram on the pinout for that connector, be nice to be able to put a resistor in there to jumper it to force the pump on at a low setting and verify it is not the pump itself.

No problem, happy to help out!  Yeah that was a good idea to get it home and assess the situation first for sure.  I'd be curious to know if that module does the trick like my co-workers 2013 PP in case I run into any other customers having similar issues.
