330ci wont start - fuel pump already replaced

New to this forum but I've read a bunch of posts that seem similar to mine, with exact symptoms. I saw all the posts saying to replace the fuel pump and that's what fixed it. I just replaced the fuel pump and my car wont start.

What happened was I was driving the car down the road from my house, and it started to act like it was slipping to me, but it kept going. The only thing I noticed was the RPM gage was dropping then going up, and reapeating until I pulled into my driveway. Then i tried starting it after shutting it off. It did start but shortly started vibrating and eventually died, about 10-15 seconds. Then after a while the car just wouldn't stay on. My car does still start but now its only on for about 1-2 seconds before it dies (with the fuel pump replaced)

I feel like I may have just wasted my money on this fuel pump, but is there any help anyone can provide? I dont have a scanner for the codes, and my check engine light isnt on. Just a Service Engine Soon light.

SES/CEL/MIL is ALL the same thing.

You are stating that the Service Engine Soon light is on, is it on while the engine is running?

So, what fuel pump did you replace, there are 2 of them, and how much did it cost you?

Was it a complete pump with sending unit or just the pump?

Picture can be helpful.

Can you hear the pump prime when you turn the ignition on?

Did you seat the pump connector fully?

Did you replace the fuel filter as well?

How much fuel is in the tank?

Does the tach move to about 100-150 RPM when trying to start the engine?

Suggest you read the 2nd and 4th link below in my signature and figure out how much fuel is in each part of the fuel tank.

The service engine light soon was never on until it died. Then it started showing it once the car dies.

It cost 250 (300 with tax) and its an AIRTEX fuel pump. It is the complete pump.


Yes I hear the pump prime when you turn the ignition on. I also could hear the old pump prime aswell. I just disconnected the connector and tried it, and it did make that motor sound.

Yes I beleive I did. I watched many tutorials on it, and followed them exactly.

No I didnt replace the fuel filter

It says it has about a quarter tank, but my yellow light is on for low fuel.

Yes it moves to about 100-150rpms

You need to put 2-3 gallons of fuel in the car, it should be fine then.

Too bad you do not read this forum. A OEM Siemens/VDO fuel pump delivered to your door is $125! Read the 2nd link in my signature.

The low fuel light should not be on at a 1/4 tank unless there is not fuel in the passenger part of the tank.

My guess is the passenger/right side of the tank is empty, it should never been less than the drivers/left side.

See the 4th link in my signature and you will be able to determine how much fuel is in each part of the fuel tank. There are 2 fuel level senders in these cars.

Currently getting gas.. If this works I will feel retarded. First off the light was on when the car started with these problems. But now it's not on. I guess I should have specified. I'll check in once in back lol

So, if the problem is as simple as running out of gas, then you might consider replacing the fuel pump again (use the OEM pump). Running the pumps without fuel causes the bearings to overheat very quickly.

Did you check for fuel pressure at the injector rail (Schrader valve)?

So I just put in the gas and it worked. I feel like an idiot. the gas light barely came on.. I'm just going to keep the new pump because idk how long ago it was replaced. Maybe that will make the gas level more accurate? The car has 204,000 miles on all original but I bought if a rich family in Beverly hills. The car is beautiful and that's why I bought it. I appreciate all the help though.

No I didn't check the fuel pressure at the injector rail. I don't even know how to do that. But I'm guessing I don't need to now that I figured I just ran out of gas?

Ps this is my first bmw, do these really dump that much gas? Because I'm really going through soke tanks and I thought something was wrong from the beginning.

Keep one of the pumps in the trunk as you might need it sooner than later (i.e fuel starvation damage I mentioned previously). But, remember, you potentially have two compromised pumps at this point. For me (2002 330i) fuel economy is 17-26 +/-

thedirtyboys, you did not run your car out of gas, your car ran out of gas.

Yes, if you read what I just wrote, it is correct.

What happened is your original fuel pump went soft and failed to have enough pressure and volume to make the siphon/transfer fuel pump in the drivers/left side of the fuel tank work properly. So then what happens is the passenger/right side of the fuel tank runs dry, even when there is about 1/4 tank of fuel in the drivers/left side of the tank and you "run out of fuel".

The fuel pump NEEDED to be replaced, the old one is a soft failure, it still works, but it is low in pressure and volume.

You need to replace the fuel filter next, does not need to be replaced this week, but in the next 30 days. Your car has the expensive fuel filter with the fuel pressure regulator built into it.

You really need to read the links below in my signature, the link specifically about the fuel pump will explain what happened.

The other thing you need is an OBDII scan tool. Less than $30 for an OBDII smart phone App and interface. Tell us what smart phone/tablet platform you are running.
