OBD-II #P008A

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.

Part is like 50 bucks, install takes 10 minutes... module is behind the rear passenger seat on the cars frame. Fold it down, pull back the carpet, right there.

is that the part talked about in that article? Do you happen to have a part number or link?

Yes it is... call Ford and give them your VIN to get the correct module. That's how I replaced mine. I was told by the service advisor that the module needs to be matched up to your fuel pump which is why they need the VIN..

Even through Ford it was about $50.

Awesome thank you for the information. When i call should i refer to it as a fuel pump control module?

 

[StealBlueSho]

Yea or fuel pump delivery module.

Got the part on hold at my local dealer. 74$

Can't complain though, as long as it fixes this

i replaced the module yesterday and am still throwing the code...

The ETC sets when the low fuel pressure is too low. The car has two fuel pressure sensors. One to measures the pressure of the electronic fuel pressure and another for the fuel rail pressure. This etc sets when the pc THINKS the electric pump is not producing enough pressure. So you could have a base fuel issues (pump or wire since we know the fuel pump driver module is good). The flip side of this is the pressure sensor is biased. What I would do is measure base system fuel pressure and compare it to P.I.D data.

I have a hard time believing your electric pump fuel system has completely failed when the high pressure system can't keep up.

Your going to want to see 48 to 70 psi on a gauge. The P.I.D. can read 15 psi more. If the engine is running disconnect the volume control valve on the high pressure pump. It's P.I.D should read within 35 psi of gauges pressure. The fuel rail pressure sensor is meant to measure 1000 of psi and can get finicky at low pressure.

My bet is the fuel pressure sensor if the car runs and accelerates like normal. A gauge will tell.

I replaced the fuel pressure sensor for the electronic fuel pressure, and still no luck. would you still suggest a test like this?

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.

They should just send you a new 3bar sensor to try out if the issue happened immediately upon completion of tune.
