    Thanks for the input man.

    Someone else chimed in earlier and said the same happened to theirs.

    Pump will be here Monday morning. I will install Monday afternoon and post back with results from Vagcom blocks 103 106 and 14.

    OK replaced new fuel pump this morning. had no issues installing seemed pretty straight forward. turned key on, can hear new pump running... waited like ten seconds before starting to prime lines and it still wont start. i found two very small tiny pieces of debris in the tank which i removed. there was a little sediment buildup on the old pump nothing crazy or suspicious looking....

    Here are numbers from sitting in my driveway trying to start cold:

    One thing i see is the fuel pressure at the rail changing from 72-60 sometimes i see it at 58psi.... could it be the fuel pressure relief valve?
    Like this?


    Also, why is duty load at 11% on lpfp while trying to start cold?

    After researching more around google, I suspect that N276 valve on HPFP is bad or going bad. The other day I was trying to start and the engine would kind of go but sputter out like it wasnt getting enough fuel... so i opened the hood and disconnected the N276 plug and then tried starting again, absolutely no firing just engine crankshaft rotating over....

    Also, upon further investigation I have learned that this is also the Fuel Pressure Regulator Valve (n276). I was thinking it was the little spring loaded valve that is on the fuel rail that relieves/balances pressure.
    So when the error code on the scanner says "Fuel pressure regulator" i wasnt sure how it could get values from a little spring loaded valve... now this makes more sense.... the N276 valve is bad.


    update: i pulled my camshaft sensor and i noticed a ton of oil sludge built up on it. I wiped her clean and reinstalled. Still problem persists. Like what this guy did. (http://www.vwaudiforum.co.uk/forum/s...unction/page3)
    update 2: cracked open the fuel line off the Fuel pressure relief valve and heard it depressurize and drip some fuel. Didnt have a wrench to get that valve out. Plugged line back in. problem persists

    After all of this I do remember one thing.


    When I went to use the seafoam the other week I noticed something odd when I removed my oil cap while the engine was running...
    As soon as i tried to remove my oil cap with engine idling, the cap was almost stuck and under a lot of suction...
    I was able to remove it and once I did, the engine started idling rough and funny almost ready to stall.... so i put the cap back on quickly after i dumped an oz or two of seafoam in the oil.

    What does this mean? Bad PCV? I understand there should be some vacuum when removed but this was like almost stuck so damn good it had me wondering....

    pulled the PCV and man was it FILTHY inside! i guess this is bad idk why im excited....

    Also i tried blowing through the diagphram on there and from either side it allows a decent amount of air through. the first time i blew air through it, i heard the diagphram move inside, then nothing all attempts after that...
    part number: 06f 129 101n
    thats what was on the car.... does it seem original?

    okay so getting back to the fuel pump , the car was running and starting fine but was just giving a code .... now you put in a new fuel pump and it wont even start ?
    I would say unless there is something you have to do in VAG com to setup the pump I would recheck my work and make sure there is not pinched feed lines or anything.

    Naw see the car wouldnt even start with the old pump, sometimes it would. It was okay about a year ago but just 2 months ago after 3 oil changes the p0089 seem to come back which would make it start rough or sometimes not at all.

    The new fuel pump is displaying numbers within spec now... did you see my pcv valve? It was loaded with sludge like it had NEVER been cleaned!! The port closest the firewall was nearly closed due to sludge! I carefully used a scraper to pull the gunk outwards... most likely will take the valve cover off and clean er out...

    New pcv valve on the way from Europa, should be here tomorrow afternoon. Ill put er on and post back results.

    So to reiterate, thus far have replaced these parts in this exact order starting from top to bottom:

    always Mobil 1 0W-40 European Spec every 5,000mi
    new N80 valve BWD
    new oreillys ignition coils
    new denso spark plugs
    new Cam Position Sensor
    new G410 Low pressure fuel sensor
    new Mann Fuel Filter
    new lambda oxygen sensor
    new VDO Low Pressure Fuel Pump
    new PCV Valve "Breather Valve" 06f 129 101N from Europa
    new fuel pressure regulator valve 126bar from ECS Tuning part no. 06D130757C <-------------- I am currently here with a funny idle and burps upon deceleration.

    next: new PCV Valve "Breather Valve" 06f 129 101N from Europa
    pictures of old valve in previous post.
    Installed the new PCV Valve... still not starting. If i put my foot all the way to the floor it sounds like and feels like it wants to start and run. Running vagcom now.

    Why is my new fuel pump working at 11%? shouldnt it be around 50%?
    Also why is my fuel pressure regulation number way low? shouldnt it be 250-500?

    What did the cam look like?

    I would double check your work. You've done a lot now and it is worth going back over electrical connectors, fuses etc. Playing parts-darts is a bit hard to track. Check voltages at starter, check earths etc.

    Triple checking is another idea but theres still questions unanswered.

    lol, i keep asking: A. how to recalibrate the new lpfp to my car with vcds but my engine wont run. any ideas on that?
    B. why "Fuel pressure regulation" numbers are so low on vcds
    C. why lpfp duty cycle is now at 11% with new vdo lpfp installed.

    can anyone answer these questions? thanks

    A - you cannot
    B - dont know
    C - dont know.

    You need to go back to basics.

    Ok, some more thoughts. Can you hear the fuel pump prime when the door opens?

    You need to get yourself a wiring diagram and follow something similar to what this guy has done. http://forums.quattroworld.com/s4s6/msgs/22583.phtml

    Unfortunately I don't have Elsawin running right now so I cannot help much further, but getting the wiring diagram and making sure the correct connections and voltages are present will be the first step.

    yes I hear the pump priming when I open my door AND when i turn the key to the 1 position, thats why this is very weird...

    Today, I took out the fuel pressure relief valve today though, and dropped the hpfp banjo bolt and I cant find it :(

    I was thinking maybe the little spring failed inside the fpr valve causing it to stick open which would bleed off fuel at all times creating a fuel loop?

    After replacing this, then ill be out of ideas.

    pulled cylinder 1 plug and it was wet with fuel and had a black on it, nothing out of the ordinary. put back in.

    replaced the fuel pressure relief valve. started car, wanted to go, going going going starting starting, FIRES UP!


    THE FIX FOR ME: FUEL PRESSURE REGULATOR VALVE part NO. 06D130757C from ECS Tuning.

    As soon as i replaced this part, the car needed a few cranks to start. im guessing priming?

    UPDATE:

    Car is idling funny even after i found that i didnt connect the pcv hose correctly. so i got it locked on now and it idles funny and burps when decelerating.
    going to run vagcom now.... im curious whats going on....

    ah not quite... went to go start her this morning and she misfires like crazy trying to start up... it was humid last night but no rain... maybe 75F this morning.

    also, my ambient air temp sensor is reads 10 degrees higher than actual... i noticed this the other day.

    going to run vagcom now. ignition coils are junk??? the spark plugs are just a little wet and kinda blackish... again i dont see anything out of the ordinary...

    why else do these engines misfire???

    kinda stumped here.

    ---------------------------------------

    I fixed the misfires by replacing ignition coil 1 for the 4th time and changing all spark plugs with new Denso's
    Misfires slightly on startup then fades away now after 2-3 seconds.

    Here is the error that i think is causing all of this and I have yet to see this one pop up....

    Mode 07: Pending emission related fault codes

    Address 7E8: 2 Faults Found:
    P0003 - SAE - Fuel Volume Regulator Circuit: Low <<<< Whats this??
    P0300 - Random/Multiple Cylinder Misfire Detected

    Address 7E9: No fault code found.


    electrical fuel issue?? okay.....

    what the car does now is drives around fine but when i stop at rest for more than 10 seconds or so and then try to take off, i put the accelerator down a little and the car hesitates to go and the rpms actually dip down so i take my foot off and ease into the accel and then the car goes and i can punch it and it will really zoom like it feels good... just taking off after being at standstill it hesitates???

    low voltage on fuel regulator circuit???

    I can't remember and don't want to read through it all again. Did you replace the PCV valve?

    I did. I do hear a whooshing sucking noise from that pcv hose

    Im starting to think i have a short in my wiring to my hpfp. i keep reading stories on google if i search p0003 about guys driving ford trucks with hpfps and they are failing or wiring is shorting causing this same error code and exact same symptoms.... i will investigate.

    Or it could be within the lpfp controller.
