Turns over, but won't start. Fuel Pump/Relay???
The other night my car was running fine! I tried to start it the next day and it just wouldn't start! Crank yes, but it would not fire! So I checked the #54 fuse and it was blown. I replaced it just to have it blow again. Then my battery went dead. Now I have it charging with the help of a neighbor, but I still need to figure out the problem. Fuel pump/Fuel pump relay....IDK. I am not the best with wrenching on cars, but I can hold my own. Trouble is that I have no experience with this type of problem! Can anyone point me it the direction of a descriptive video or soimething with pictures? Please help...I gotta get back on the road!

ummm...
what is that #54 for? Aha! Fuel pump. So, obviously, current is being drawn.
I've read of stuck relays before I'am fairly sure... I'd take it (fuse) out and use a meter and determine, if possible, with help of a wiring schematic, if a short exists back at the pump (under the rear seat-cushion), or between the fuse output-side and relay or etc. etc. Disconnect all wiring to the pump and look for a short there or in the wiring or whatever. Locate the relay and use the meter to see if contacts are stuck or whatever. Exploded parts drawings at RealOEM.com bmw parts or in your Bentley BMW work manual would indicate. Might also disconnect the battery negative so as not to confuse the electrical system in general/throw codes, etc. I see yours is a 2000. Not necessarily your immediate problem but, how about the fuel filter? Might change it sometime...

Rowdy...thanks for the reply. But I am very confused! I do not have a meter handy, and I am trying to find the relay, but I am scatterbrained right now! I hate feeling dumb! Do you know of any videos or pictures to aid in this problem?

Fuse 54 keeps blowing! I have been searching these forums for awhile now with no luck. What is the fuel filter relay? Where is it found? How do I swap it with the horn relay? When I look in the glove box and pull down the fuse panel, I just don't understand what needs to be done next...

probably a bad fuel pump drawing too much amperage. possibly the relay...some relays are behind the glove box and some are in the dme box

Does the fuse blow immediatly or does the pump try to turn but then blows? My pump went bad when there was bad gas at the local gas station. The pump and fule filter was replaced as the pump would quit after trying to get fule through the clogged filter.
Be careful, it is gas!

the fuel pump is so cheap and easy to replace on the car (definitely diy) honestly its worth it just to replace it anyways. i did mine just for kicks. definitely noticed a nicer power band. It is under the back seats. you change it from inside the car.

Question... When you turn your key in the second position you should hear the Feul pump noise for about three seconds. aside from a faulty feul pump. what else could keep the fuel pump from making that noise?? My fuel pump died on me (stopped making that noise) Changed the fuel pump myself.(thanks to the DIY section) soon as I finished the car started right away!! Complete with pump noise. Three days later I got out and it doesnt start!!! No pump noise!!! the pump was brand new from the dealer....could it possibly be bad or s there something else I'm missing??
Please advise. 2002 BMW 325CI |
