What is the average life of a fuel pump for our cars? My car has stalled on me about 4 times in the past 2 months and after talking to a friend we both think the fuel pump is starting to die. I took my car in for a check up 2 weeks ago and they couldn't find anything and all they said was that it will be easier to find the problem when the car dies and doesn't start again. Anyone here had their fuel pump die at around 83,00 miles or think mine is going out or could I have another problem? Thanks. | | | 03-12-2007, 09:48 PM | #2 | Senior Member Join Date: Jul 2004 Location: Florida Posts: 1,595 | Well I went to my friends shop and asked him about what's going on with my car and he thinks it's the idler control valve, maybe TPS, or AFM? I'm thinking it could be something in that area because when a get to a red light and drop on rpms the engine starts getting ready to stall so then I go into neutral and hit the gas and the engine is running fine before I go back into gear. Any ideas what could be the problem? Could it be one fo those things or fuel pump? If it's the AFM then that would be great because I am planning on getting the Miller MAF. Thanks. | | | 03-12-2007, 11:29 PM | #3 | Senior Member Join Date: Jan 2005 Location: TX Posts: 140 | When starting the car does it sometimes crank continuously for a while but have trouble actually starting? If so, it's probably the fuel pump. I just replaced mine and the car is a 96 with ~140k miles. However, I never had trouble with the car stalling, so it could be something else. When did you last replace your fuel filter? | | | 03-12-2007, 11:56 PM | #4 | Senior Member Join Date: Jul 2004 Location: Florida Posts: 1,595 | The first 3 times it happened it took like 2 cranks, but today it took me 1 crank. I have never changed my fuel filter unless it was done during inspection 1 or 2. I did inspection 1 again around this time last year. | | | 03-13-2007, 01:36 AM | #5 | Site Moderator Join Date: Feb 2005 Location: Naples, Florida Posts: 238 | My Ti had the same problem, never fixed the problem though. My old car had over 300k+ miles on it and all I remember changing was the Idle control valve and the fuel filter, but not the fuel pump. It ran strong for the most part except for when you stop the revs would bounce up and down, sorta like what you explained. __________________ Nick 1995 BMW 318iC.

TPS would be for low or high idle high idle could also be an air leak hesitation on accl. is usually TPS incorectly set , loose throttle cable or faulty AFM "jumping" from low rev to high instead of gradual increase is faulty afm from low idle to stall, fuel pump faliure __________________ Vin Number decode and Retrofit Pdfs Available Free !

How to remove it is the question now? | | | 04-01-2007, 10:04 PM | #9 | Senior Member Join Date: Jan 2005 Location: TX Posts: 140 | The article below has step-by-step instructions. It's a pretty easy procedure. Make sure you tap the black plastic retainer ring counter-clockwise rather than trying to pry it up. Replacing the fuel filter at the same time as the pump is recommended. http://www.pelicanparts.com/bmw/tech...-Fuel-Pump.htm | | | 04-01-2007, 10:52 PM | #10 | Senior Member Join Date: Jul 2004 Location: Florida Posts: 1,595 | Thanks. | | | 04-01-2007, 11:07 PM | #11 | Senior Member Join Date: Feb 2006 Location: Fl...tampa area Posts: 320 | just get the whole assembly thing its a 5 minute job. i htink it cost me around 160 or 170 to get the assembly. just pull the back seat bottom out, and instructions are on that link i guess. its simple | | | 04-01-2007, 11:31 PM | #12 | Senior Member Join Date: Jul 2004 Location: Florida Posts: 1,595 | Already purchased it and have it on next day air delivery from KO Performance for $114.

I'll bring my camera just in case. | | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
