    Fault codes

    I’ve got a 2001 x5 3.0 that’s turning over but won’t fire! New plugs, fuel filter, cleaned injectors, new coil pack as well. Im reading a few codes and could use some help in what direction to go from here. Also vehicle sat for almost 2 years with half a tank of fuel.

    Fault codes-
    00008b instrument cluster
    0000ff Gateway/zke
    000009 steering wheel/lenkrad
    000011/0000f0/000005 airbag


    Any thing to help would be greatly appreciated!

    Welcome to the forum.

    None of those codes is relevant to your no start.

    You DID drain the ancient fuel and refill with fresh, right? After 2 years, gasoline turns to varnish. Changing the filter, and sending the injectors to a professional injector shop (like RC Injection) are great ideas, but running the old varnish through the new filter and refurbished injectors undoes all that work.

    Beyond that, you need to find out just what's missing, that's preventing the engine from starting. You need (1)spark (2) fuel, (3) air, (4) compression.

    Fuel is made up of two items: correct fuel pressure at the fuel rail (51 psi), and fuel injector pulse.
    You need to check for spark, by pulling out a coil, put a spark plug in it, ground the threads of the spark plug, and watch carefully for spark while someone turns the key and cranks the starter. If you don't have spark, the computer is probably not trying to start the car.
    If you DO have spark, that rules out many possible culprits, so that's your first test.

    Your fuel rail has a schrader valve (like a tire valve), so that's where you'd hook up a fuel pressure gauge....or, at the very least, push the valve and see if fuel squirts out under very high pressure. (Shield your eyes!)

    Thanks for the response! I’m going to Remove the fuel next. My biggest concerns where the codes and hoping it was a simple fix! I do have spark but I haven’t checked for the pressure in the fuel rail so I will check that as well!!

    Definitely check to see if you have fuel pressure. Without it, it'll never run!

    So I pulled the back seat removed fuel from both sides of the tank. Wiped them clean and spotless!!! Added new 93 fuel and seafoam just for extra scrubbing!! I’m getting 12v to pump and sending unit from other side of tank. I discovered the fuel pump filter bag thingamabob was split and the pump insides looked all gummed up. Also pump seems to be getting warm while trying to start! I’m replacing tomorrow as soon as amazon man shows up. I know I’m getting spark. After cleaning injectors the car started for a few seconds from the carb cleaner!!! Wish me luck

    You need to know that Amazon is the WRONG place to order BMW parts.

    You need to buy an original OEM pump, which in this case, is made by DELPHI. I recommend FCP Euro for this, and return the Amazon thing.

    https://www.fcpeuro.com/products/cop...x5-16116755043

    I like Amazon just fine, but I would NEVER buy an important BMW part there, because you'll almost certainly be buying junk made by "URO" or similar faulty suppliers.

    I purchased the Delphi Fg1230! I may have paid a little bit more the necessary on Amazon but I made sure not to buy a cheap Pump. How is the shipping from FCP euro pretty quick?

    Glad Amazon was mentioned. Unlike parts from many of our competitors, most URO parts are rated "four stars" or better on Amazon. We actually keep an eye out for items with low ratings there, because it's more rapid and reliable feedback than we get from smaller retailers who might simply throw away returned items that are defective without contacting us. Any item we find with a poor rating on Amazon (assuming it wasn't a case of the buyer simply buying the wrong part, which is common) is reported to our engineering department for review and corrective action. So items that had poor reviews several years ago have likely been corrected since, and new reviews will eventually reflect this.

    Until then.....

    I'm sorry to say this, when you're a supporting vendor now - but URO is going to have a tough row to hoe, at these forums. There is a reputation already established, and every time I've tried to believe there's a "new sheriff in town" at URO, the products continue to be, um, faithful to their heritage.

    Amazon sells good stuff, and bad stuff. They should never be considered a viable source for quality BMW parts. They have NO idea what they're selling, or which car it fits, and VDO / Bosch /and other quality manufacturers are usually not even mentioned, because some absurd Chinese garbage is cheaper.

    Buy BMW parts at BMW specialist retailers who make it clear what quality of part you're buying: OE and OEM, or ....well, you row.

    OK I replace the fuel pump still getting voltage about sending unit and fuel pump. Still not firing. I don’t have any pressure at the fuel rail after attempting to start the car a few times. Any suggestions? Fuel pressure regulator?

    You've got power at the fuel pump, but do you hear the pump running when trying to start? Maybe have someone else listen just to make sure it's kicking on before spending time troubleshooting upstream from the pump.

    Are you getting 12+ volts at the large fuel pump feed wire? There are a couple of places that get voltage in that plug: do you have power at one of the LARGE diameter wires ? Do you hear the pump running when the key is turned to the on position? (It should prime for 2 seconds ).

    On your car, the fuel pressure regulator is built into the fuel filter. If the filter has been replaced, it's possible the fuel lines were switched feed and return. That said, X5's rarely get their filters replaced, because they're a bit difficult to access.

    IF the new pump runs for 2 seconds and you can hear it, but you have no pressure at the rail, either:
    The filter is completely clogged, or
    the fuel lines are hooked up incorrectly at the filter, or
    There is a metal fuel line which has been crushed, or a rubber one that's badly kinked.

    EDIT: The fuel pump power wire is white with a blue stripe.

    AND, I want to thank the URO rep, for being here to assist with diagnosis, and coming back with an excellent answer. I respect that the company, and their representative, is here to show us that they're willing to work above and beyond previous conceptions, and continue improvement.

    I tested for 12 V directly off the two wires going into the metal cylinder pump while pump was removed from the tank so 100% sure I’m getting 12 V to the pump itself. I did not hear anything but nor was I listening for it when the key was turned off. I also replaced the fuel filter along with many other things recently. I replaced them line for line. It has two coming in and one going out and what seems to be a small vacuum line on the output side. The connector for the small vacuum line was dry rotted and I did replace that. I was thinking of disconnecting everything and blasting it was some dry nitrogen to see if I had any clogs! From what I know this is the E 53 but there are no electronics connected to the fuel filter as if it was a fuel filter and fuel pressure regulator as well?!.

    It’s alive! There was no fuel in the fuel pump side of the tank LOL. I poured a gallon in there directly and she fired right up running just under 50 psi fuel pressure! Just curious how does that process work from the sending unit outside to the feel pump side? Should I be concerned that it didn’t pump fuel over there with just turning the key? Mind you I did empty both sides of the tank completely and only put fuel in the sending unit side after cleaning them out.

    There is a PASSIVE fuel transfer system, called a "sucking jet pump" (really, I don't make this stuff up), which brings fuel from the opposite side of the tank to the pump side. This bunch of plastic pipes may be disconnected, in which case, you may end up running out of gas again, when you still have a half tank....on the wrong side. However, when you put gas in the car through the filler neck, on an E53, it goes into the pump side first.

    Your fuel pressure regulator is non-electrical; the vacuum line does cause the pressure to rise and fall somewhat due to engine demand.

    Fault codes

    So I got a question. Car is running great starts up just fine. After the initial start up no matter the distance I drive or time it sits during that day it has a long start after. Sometime takes 2 to 3 turns of the key before it I’ll fire up. Any suggestions?
