1. Starting fluid, if the engine starts and dies, then you have 100% confirmed you have a fuel delivery issue.

2. You need to read this link, http://forum.e46fanatics.com/showthread.php?t=929501 since you are using a mobile app you cannot see my signature.

3. Does not matter how good you are with a Voltmeter, you WILL get lost. It has to do with the way the BMW circuitry for the fuel pump works. You will see a constant 5 Volts or something close to that at the fuel pump connector, then chase your tail. Order a fuel pump, suggest you do it directly via BMAParts.com. They are in CA, however, in VA I received my package the next day. The label showed BMA in CA as the source, but I went in and checked the UPS tracking info and it came from PA or DE, so this is why I had it the next day even though it was UPS ground.

I would be careful about the cheaper BMA pump on Ebay. BMA has multiple suppliers they use, most here go with the Siemens/VDO pump as I recall?

It is around $125 with the SpecE30 discount code.

If you need to get the car started, might be able to bang on bottom of tank or top of pump to jar the commutator to get the pump started for a drive??

I don't see a fuel pump relay fuse... All I see are all the listed fuses on the diagram and the only one pertaining to fuel is the fuel pump fuse, not a fuel pump relay fuse... and I don't see any relays BEHIND the glove box... any guidance or pictures would be helpful. thank you.

THAT sir was a freakin awesome write up. I will definitely do as you recommend. It's a 2001 and I had it for almost 3 years I think. don't have any maintenance records from previous ownership. sounds great. i will go ahead and replace all three as a CM/PM effort. I thank you for your input. Awesome.

Any special instructions on filter replacement. Or will the normal instructions for most any car suffice. I have a collar set for inserting on the fuel line to assist with removal... can I use those?

2001 car, trust me, 90%+ chance its the pump, even if it not the pump at this moment, your car needs a fuel pump.

You have to removed the glove box door and the glove box liner to get to the relays, I think there are 5 in there as I recall?

You will be happy once the pump is replaced!

Fuel pump has standard worm drive clamps or you will need standard worm drive clamp as the current ones may be crimp style??

Check the fuel pressure regulator vacuum hose as well, this breaks and causes vacuum leaks and CEL to come on.

After reading your write up, it dawned on me that just the other day, it seemed like my acceleration had been declining in vigor lately... so, I will just do this. Even if it doesn't fix the problem (which i am sure that it will), it will be done

There is a pre filter attached to the pump assembly.

So here is my BMAparts.com order

I wanted you guys to see this to make sure I haven't missed anything here or if there is something else I should keep in mind.

The fuel pump was cheaper on the BMA website than on Ebay!! so that is good.

the SPECe30 code worked like a charm and saved me 10 bucks.

Altogether, the order comes to about 190 dollars for the new fuel pump assembly, o-ring, and filter. I think this is great, but wanted some input before I pay the money for it. to make sure there isn't another part I'm missing to be able to complete this job.

Thank you guys. You have made this a lot less stressful.

You need new screw clamps for the hoses. And, I know when I did fuel filter, I replaced a few of the sections of fuel line that were easy to do...probably not essential.

There are minor differences in screw clamps...you could call and ask bma if they have choices, but I doubt it.

I believe I actually got all my clamps from the dealer...one of the cheapest OE parts you can buy...and I like the little roundel! Not a big deal, I don't think.

Just don't over or under tighten. You want it just compressing the hose, not deforming it much at all.
