    Wont start after fuel pump install

    Guest-only advertisement. Register or Log In now!
    Installed new fuel pump (OEM with DW300 pump) and the car will not start. I cannot hear the pump prime. Am I missing a step? No codes.

    Logically this would suggest a defective pump, but likely the control module. Have you a 12V source then test the pump but disconnect all other wiring.

    Just replaced a fuel pump on an a8 where it sits in a "cup" and gravity feeds itself fuel.
    If not seated right or very low fuel it wouldn't start.
    Did all this work and still wouldn't start,checked fuses relays etc
    Replaced fuel filter ,back in business

    Pull it out and check the work. I know your fuel pump came preassembled but who did the assembly?

    Check the wiring for your aftermarket controller before you do that though. Maybe you disconnected something by mistake. You could always just plug your old factory fuel pump controller in first if you still have it and see if it will prime. That would eliminate the pump as the cause if it works.

    Your friends at JHM did the assembly.

    I plan on going over all of the items touched yesterday. I will start by plugging in the old pump and see what happens. That should let me know whether its the car/electronics (a friend suggested I replace the fuel pump relay), or the new pump.

    Probably done by the same guy who adjusted my wastegate or pressure tested my replacement intercooler tube.

    I wouldnít let their shop change my windshield wipers now.

    Logic states that the new pump is what changed so thatís the probable cause but you never know with how modded your car is from stock.

    Good luck. It sucks that you canít just buy something from a so called reputable source and have it just work right away from the start. 🤣🤣🤣

    Hopefully Iím wrong and Iíll have to eat my words but my track record with them is on my side 😉

    Having owned a DSG car (it was only a TDI though), Iíd gladly trade my manual A4 for a RS3 😀

    The only thing I didnít like was paying for the fluid and filter every 40K.

    So I am sure at this point I have a dead or dying battery. VagCom says 10v, windows slowly crept up, and the radio is acting funny.

    I can hear the faintest whine from the pump with the key in the ON position, but there doenst seem to be enough to turn it over.

    The Boost Manager devise running directly to the fuel pump is indicating that it (the BM+) is powered on and normal.

    Fully charged battery installed and it started right up. After a few minutes of idling as I picked I shut it off and tired to restart - no go. Tried again after inspecting stuff and finding nothing and it started up.

    Perhaps its just 'new pump' behavior? Im going to grab vagcom and go for a spin.

    It should work the same every time you start it. 😀

    So far youíre 50/50. That ainít good. Are you getting a no crank no start or just a no start? Do you hear the pump prime every time now?

    The couple of stalls might be a fluke (or due to the cracked PCV breather hose.. add that to the list of repairs.).

    I have taken a couple of logs, see below. 280g/s and no dips in fuel pressure. I will need to take some additional logs as the car feels a little slugglish.

    The car sat over night and just fired right up as normal. The pump seems to be working as it should.

    Over night the battery voltage per vagcom was 12.1v. Does that sound about right?

    Now on to more fueling logs! I need to determine what is causing my P310b codes (2) - both at idle.

    +12v cold, +14v running and +10v cranking is what I would consider a good battery.

    Well you know from your logs that you donít have low fuel pressure. Youíre meeting or exceeding HP and LP. CoUld it be leftover codes from the no starts of your old pump or the issues you had with the new pump yesterday?

    Could it just be from all the aftermarket stuff youíre running?

    Honestly, I think it is from the banjo bolt on the hpfp. It's damp and it reeks of fuel within a one foot radius of the pump. It smells dangerous.

    Just curious, are you tuned for the bigger pump or will the ecu compensate enough to not flood?

    I think he can also edit his fuel map from the controller set up he is running.

    Iíd be interested in seeing the lambda logs.

    Correct, I have semi control over the stock A4 controller. I can run the full OEM program, the OEM program until a set point I determine and then my own mapping, or fully from scratch mapping.

    Right now I am running a tweaked version of the Eurodyne BM+ base map for the 2.0T with a stock controller and uprated pump.

    The post you quoted was meant to say you donít have a fuel pressure problem. Youíre meeting or exceeding fuel pressure requested for most of the log.

    If you got a leak there you should take care of that though 😉

    The low pressure side should regulate itself so thereís not really any need to modify the tune, Iím pretty sure. The injectors are run off the high pressure side so the low pressure side is just a ďdumbĒ supply, more or less.

    You canít really have too much fuel on the low end, but you can definitely have too little.

    You canít really have too much fuel on the low end, but you can definitely have too little.
    By modify the tune I mean modify the LPFP controller mapping.

    I am still getting high pressure codes at idle. P310b.

    I would consider 12v low. I would expect 12.6 . Just keep an eye on it.

    Iíd agree. The battery should be upper 12s resting voltage.

    Thatís why I said +12 😀

    If VCDS told him voltage was 12.1, I wonder how accurate that is compared to actual voltage at the terminals.

    Well it depends I suppose at what component youíre reading the voltage at. If there are shorts or draws between the battery and a specific component you might see differing voltages being reported.

    If everything is healthy I would expect the voltage readings in VCDS would be quite accurate.

    Thatís what I was saying. Whatever is telling him what the voltage is currently is also drawing voltage to operate.

    Doesnít matter as it seems his car is running now.

    Looks like he is chasing a boost leak or wastegate setting issue now from PMís weíve had. Heís not reaching full boost until like 5k. And he has a huge dip in high pressure and a huge spike after it.

    What do you guys know about the 3 wastegate packs these turbos can run. Could he have the low boost pack installed and need a higher one? Hereís the EFR training manual if anyone is interested in reading it. Wastegate info starts at page 25. The manual says that the default wastegate canister is medium which is for 12-18 PSI and there is a high boost canister for 20-30 PSI. Maybe he needs the high boost canister or maybe he just needs to adjust the rod on his default medium canister.

    Theres slide plugs on the pump. Sometimes they slip off. The cars runs terrible then wont start anymore if that happens. Or it may not start. I would check that
