OBD-II #P008A

P008A - Low pressure fuel system Pressure to low

I have a 2013 Ford SHO PP with livernois 93 v10 3 bar tune. (66k) [tuned 300 miles ago]
LMS intake
LMS 160 Degress thermostat
LMS 3 bar
LMS pre gapped spark plugs
LMS tune

I am reading this code with their "My Calibrator". I contacted them and they suggested switching back to 2 bar and loading stock tune, to see if the problem continues, and it sure did. I have a very ruff idle when at "operating temp". My question is, what parts make sense to replace? coming from a diesel truck, fuel pressure regulator seems to make sense, but i cannot seem to find a part. I have found a fuel pressure sensor, (MOTORCRAFT CM5223) but am unsure if this will rectify the issue. I would rather not just throw parts at the fuel system. I will of course if i have no other options. Any insight? Appreciate any response.

*i did try to search the code on this forum, as well as google and cannot find anything pertaining to the specific vehicle*

Did your year have a recall on the fuel pump, and if so has it been replaced on your car?

 

[Ohitsreggie]

Ah honestly I am not sure.

Check on owner.ford.com to see what outstanding recalls/FSAs there might be on your SHO.

This is all im getting.

• FSA Title: SYNC WITH MYFORD MYLINCOLN TOUCH WARRANTY EXTENSION COVERING ACCESSORY PROTOCOL INTERFACE MODULE APIM
• Field Service Action Number: 12M02

im not sure what it is, but it doesnt seem related to the fuel system. damn...

Is there any smoke coming out of the tail pipes, particularly white? I would pull the plugs too and check for excess fuel on any of them...

Leaky injector seems to be common failures on these platforms...

 

[Ohitsreggie]

No smoke, and i just changed the plugs a few weeks ago nothing seemed abnormal. and the code existed before changing plugs.

so i switched back to 2bar sensor and stock file, hard idle went away and code is gone after. even after a few days of driving. called livernois and there still convinced its fuel pump related. seems like the obvious thing would be faulty 3 bar sensor... not sure where to go from here.

 

[StealBlueSho]

Yea.. when you switch back to the stock 2Bar file you HAVE to switch to the 2Bar sensor or it won't run right...

Grab another 3BAR off rock auto for like $50...

 

[Ohitsreggie]

Yes i understand that, and that is exactly what i did. im confused how there first reaction wasnt "well send you another 3 bar" since the issue has been ongoing since day of install.

 

[StealBlueSho]

You live in the MD/VA/DC area?

 

[Ohitsreggie]

Chicago land area.

 

[StealBlueSho]

Damn, was gonna offer to meet up and swap out the sensors.

 

[Ohitsreggie]

i appreciate that. just kind of confused with their conclusion. i dont mind ordering another one, but i was trying to support them. i knew i could get the sensor from rock auto for cheaper to begin with. LOL i guess i should have just done that to begin with.

 

[StealBlueSho]

I'm a little confused at the first post... when you switched back to the stock tune and still had problems, did you switch out the MAP sensors as well back to stock? Or had you accidentally left the 3BAR sensor in when you switched back to stock?

Cause in a later post, you said everything was running well with the stock tune and sensor?

 

[Ohitsreggie]

Yeah i must have not swapped sensors

so i switched back to 2bar sensor and stock file, hard idle went away and code is gone after. even after a few days of driving. called livernois and there still convinced its fuel pump related. seems like the obvious thing would be faulty 3 bar sensor... not sure where to go from here.

Check the part number on the 3 bar sensor in front of the TB. If it's the same you could simply swap them and see what happens.

 

[Ohitsreggie]

so i loaded their 2bar 93 octane tune (with 2 bar installed) and am still getting the same code. anyone have a part number for a "fuel pressure module"?

 

[Ohitsreggie]

is it this?

Livernois sent me this article pertaining to a similar sounding issue, but the problem is i can only get the code to pop when tuned. so i am just going to replace it myself outside of dealer to be able to run 93 v10 3 bar tune.
