rough idle no accel response and P0087 code

[lamrith]

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;

• LPFP and sender (PN DA5Z*9H307*F)as the gasket set (PN 4L3Z*9276*AA)
• Fuel pump module ( anyone have a part number?)

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!

Thanks Z!!

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

YOU D MAN Z!!

Looks like the only thing outstanding on my vehicle though is the APIM Warranty extension.

I would try to rule out the LPFP unit. Z

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.

You thinking it might actually be the HPFP instead of the LPFP or relay?  I will post some picts in a few min.

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. 

 

[TopherSho]

as a recent victim myself, your oil would smell ...

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

I think SHOdded meant PICS of the FDM behind passenger rear seat!
The plugs look overly well done!
R those the original spark plugs! Some new COP are in order

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.

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.

 

[lamrith]

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.

 

[SHOdded]

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

 

[lamrith]

Few picts.  Sorry not greatest, phone would not connect to PC to edit

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.

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

 

[lamrith]

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?
