?????? Hit bump ????????

While driving the pot holed filled mess called city streets tonight I hit a pothole pretty hard on its edge and car instantly fell dead.!!!!????? Pulled into parking lot and it started right up, but with a slight miss. Drove another 10/15 mins and was on my block to go home and fell dead AGaIN!!!! This time it hang over a few times before it started( the out of gas sound) when it did start I drove the block normally, pulled into driveway and sat in car about 10. Minutes running and it idled and purred and responded to a few pedal mashes with no problem. Any ideas what happened, what I need to address etc

Must have been a pretty big pothole.

Have you had a chance to take a peek under there and see if there is any damage to anything. may want to remove the plastic shield and take a look and see if anything got smacked...

Driver side fuel pump?

in looking at the diagrams, and maybe im mistaken, it shows only one fuel pump in your model year.

http://realoem.com/bmw/showparts.do?...94&hg=16&fg=15

I do see, two fuel level sensors, one for the left and one for the right.

Are you talking about fuel filter, because that shows only 1 as well...

just curious if im missing something...

As for the actual issue after hitting the crater in the road, im not completely sure, are there any warning lights on the dash on, cel, anything...

Question

Thanks for the picture, I was thinking 2 fuel pumps since when you move the seat you see the same set up on both sides. So there is 1 pump but 2 sending units. It was a heck of a pothole, and car went straight out, I only realized it because steering went tight! Then again just died a block from home, note,,,,,,, before pothole, and after pothole it was running 65/70 miles per hr no problems, so just trying to see if something got jarred

There are fuel pump fuses in the ebox in the engine compartment. On mine it is 17 and 22 I believe, mines a 97.. The fuel pump relays are in the trunk above the battery behind the carpeted covering. Mine are light green and if you are looking at the fuse carrier, mine is the second one in from the taillights.

The fuel filter is under the plastic covering along the passenger side door under the car.

Fuel tank is under the rear seat, the door for the fuel pump is on the passenger side, when you remove the rear seat, there is a rubber covering, you need to cut away, should be pretty evident when looking at it if you are going to get into your fuel pump for whatever reason...

Again, everything i have mentioned is based on my 97 m62, but i dont think there is much design difference in the layout. But I could be wrong of course to which someone will correct whatever ive said.

Note im just answering your questions, im not positive what caused your car to quit after hitting that crater in the road...

If the CEL is illuinated, then you need to read the codes before spending money at parts. The DTC (diagnostic trouble code) will point you in the direction of why the CEL illuminated. If you don't have an OBD II scanner/reader...I think you can get them read for free.....OOOPS!

Never mind...just remembered this is a 1995 M60...which means you're OBD I...which means you can do the STOMP TEST to figure out the DTC (if you don't have anything that can read the code for you).

The CEL light indicates an issue with exhaust emissions:

Scroll up to the top (LEFT) of the page and look for USER CP (its in a black band across the top of the page). Click that link and you'll see options along the left side of the page...if you click on EDIT DETAILS...you should see a box that allows you to change your car info.

Or you can click on the EDIT SIGNATURE link and create a signature that includes you model/model year/build date...plus any other info you'd think it would make it easier for the forum to help you better.

Since you are OBD II...you can have the codes read for free from most auto parts stores like Autozone/Pep Boys/Advanced Auto etc (if you don't have and OBD II scanner/reader.

This will point you in the direction...or you can google the DTC code (just type "BMW P_ _ _ _ _") and you should get multiple results that may describe and give suggestions for how to solve the problem. Or you can post the DTC code here.

Okay, im not going to say this is what your experiencing but this is all i could find in relation to the symptoms you seem to be having. IE when Braking car shuts down...

roll to page 7

http://www.e38.org/DSC.pdf

Im sure someone else with a ton more knowledge about these systems in the car will be able to elaborate more or point you in another direction...

Maybe when hitting that crater it screwed up a sensor on your car...

Thank you, I'm going to check fuel pump relays, pull flap and possibly change fuel filter, and look closely to see that I didn't damage anything under there. But from what I read, seems like sudden braking shuts of fuel in the event it's a accident and car does not catch fire in event of impact?

Ive done hard braking and never experienced it on mine. I mean from 40 and slamming my brakes, never had the car shut off, thats why im curious if a sensor or something was damaged. But again, im and by no means an expert on this, just sharing what i found during a google search...

good luck, let us know what you find..

Nice ride by the way, i like the mpar rims.

Thank you on the car!
Slamming that pothole may have jarred a sensor somewhere, cam position etc, I'm doing all this reading and googling, there is a plethora of info to digest and attack! Love the car so I guess I have work to do

may want to get the codes read on it. I bought a cheap code reader at autozone that does the trick nicely. it was like 30 bucks. granted i had to go look the codes up on the internet, but i didnt care.

It might lead you in a direction.. I think you said your cel was on..

fuel filter is located on the passenger side of the car, under the plastic covering under the car under front door. You'll need to jack the car up a little to get to it comfortably.

as for the relay. not sure where you can pick one up. I cant imagine it being even that expensive from a dealer, unless you dont have a dealer close by...

IMHO, dont go throwing cash at parts that might be fine. but that is obviously your choice...

Ok, interesting place for pump, because that's the tire( right) side that hit the crater

no under the car is your fuel filter, pump is under the rear seat. if you grab the rear seat from the center and pull it forward, it will expose the fuel tank. there is a rubber bladder around it. the access hatch for the fuel pump is on the passenger side of the car. You should be able to tell where it is. I think if memory recalls the rubber bladder is perforated.

The fuel filter is the one under the front passenger door (approximately). You have to remove the plastic shielding to get to it. You cant miss it, Its a silver cylindrical looking tube. with two rubber tubes going into it. One in the inlet, one on the outlet. It will be obvious once you drop the plastic shielding...

here is an image to what the fuel filter looks like

http://www.google.com/imgres?imgurl=...ed=0CDoQ9QEwAw

here is a video link to the fuel pump..

http://www.bimmerboard.com/forums/posts/754001

again, before you go throwing cash at parts. make sure you know what is causing your issue... thats my disclaimer...

I got your message within the parts request Will. I can't say I have heard of this before. I don't believe the 740 has a fuel cutoff switch, as I know them anyway. The fuel pump relay is in the row of relays above the battery, second from right. Without researching it again, I believe when the car is in an accident, the airbag module triggers the appropriate airbag. The DME detects this action and stops fuel and spark. I think it does a few other things like turning on the flashers. This could just be an electrical quirk. It's a stretch but if it were mine, I would give it a battery nap and touch the cables together before putting them back on.

Then get your codes read. Perhaps you cracked your crank position sensor or something. Make a note of the codes and then have them cleared. Drive thru a number of cycles and have them checked again. JMO

Went out this am, located fuel filter, looked good no damage from pot hole, checked all fuses under hood, replace any that we're in wrong place( ie, 15 that may had a 20) checked all fuses in rear, done the same, cleaned all relays with wire brush( tarnished pretty bad) gave her a battery nap, washed and waxed, drove around ALL day and coming home came to stop light with 50 ridges( you know the type of grooves left by big trucks) bumpbumpbump etc, sitting there and realized it fell dead!!!!! But started right up, I'm thinking camshaft sensor, crankshaft sensor etc, don't know just guessing, but I do know the succession of bumps killed power! Tell me what you think guys!Click image for larger version

Ummm. can't see anywhere in the above posts where you might have checked the battery connection? Transient 'total shutdown' episodes are pretty rare, and in my experience (not that I have experienced such a thing in my E38) are rarely due to just one relay or fuse. Maybe when the fuelpump was replaced the tech just forgot to tighten the battery terminals, and one is just sitting there jumping up and down over the bumps ....
