Battery is in trunk compartment. Must be positioned exactly and locked down. Not easy to do and keep in position unless using BMW battery. There is a slight size difference (BMW wants to sell their batteries - at inflated price.) Save yourself the headaches and get BMW battery. In the meantime, just move your battery position a little bit until trunk light comes on. Car will start if trunk light is on - unless the problem is really something else. Hope this helps. Let me know.

I would first check the condition of the battery. If the battery is okay, that is it puts out enough current to operate the starter. I would then check for a short. The battery would be dead in a couple of hours only if there is a short or another load on the battery.

No power and batt is good


My first guess would be a dead cell inside the battery, or a blown fuseable link between the battery and the fuse box.
Someone would need to check the battery connections and fuse box with a meter.

I jumped car off it crunk on its own fora day,then batt went dead again,this time it won't jump off. It wants to crank but won't turn over.


not sure what you said but.
seems the battery is discharging,? 12.6v is fully charged,
own a voltmeter?
try a good loaned battery , does it start the car,?
i think you meant?
i can jumper cable start my car at any time. (off another running car)
but after running my car, the battery discharges and it will not crank at all. right?
this means ,the charging system on your car is bad.
if the starter cranks great, then the engine is flooded or is in great need of a tune up (sparkplugs etc)
if flooded try the super secret in the op guide, crank with throttle wide open , this magic trick cuts all fuel injection allowing the flooding
to purge away, and eventual starting.
my guess 2 is the car wont start, so you crank the battery flat
you jumper start it and it runs. (luck)
then day 2, same deal cranks ok but wont start.. ever tune up the engine?

98 Deville had a dead batt. Replaced, turns over but wont start


Sounds like fuel issue, remove the black plastic cadillac cover on the top of the engine, then find the fuel rail on top, and remove the black tire cap looking thing on the end of the fuel rail. Now you will have to get a fuel pressure guage ($45), and screw it on right there. Or you can also just poke that little valve with a ink pen to see if any fuel squirts out, it should come out with alot of force, it is like a valve on a bicycle, it only lets fuel out when you push on the valve ***. As for the battery being dead perhaps you left your parking lights on? My 97 deville, had a cold start problem, that it took 5 minutes of cranking off and on, to get it cold started, but after it was running it would start throughout the day just fine. I ended up replacing the fuel pump in the tank, and the fuel filter on the rail.

1994 BMW 740i with 222,000 turns over but won't start. Removed battery, had it tested and it's good; radio, lights, windows all working fine. Driving the car on Friday, went to start it on...


Hi.

If it does turn over and electrical works, then the problem is unlikely the battery. You can try jump starting. If it cranks when jump-starting it may be a weak battery, starter motor or alternator, but I don't think that this is the problem.

Check if there is spark on all cylinders. Do a code scanning (this car is OBD1, you will need to do the scan at the dealer place or to find a BMW OBD1 tool- Universal OBD2 scanner will not work on a 1994 BMW). If the codes return misfire or mixture related errors check fuel pressure, check sensors and parts that determine the mixture (MAF/MAP, AIT, O2 sensors, IAC and EGR system), check the vacuum system for leaks and check the crank sensor.

Regards.

98' Cav.. Drove it to store, shopped, didnt leave anything running or turned on. Went to car, opened dr...no dome light (thought, hmph, must have burned out -- fix later). Tried to start car... I turned...


this sound to me like at first I thought it was a fuse, as the problem went on it shifted more toward a weak cell in the battery, if a weak cell sits for a little while the battery will not hold the charge in that cell and that will cause loss of power, "its charge", in tne other cells. you had mentioned you used another battery and it ran great but when the battery was removed, things went wrong. You may check to see if there is water in your battery

2002 BMW 740i will not start


Take your battery to the parts store and have them test it. If its an original replace it anyways batteries only have a 5 to 7 year life span. on another note when your window walked off they may have damaged a switch in the door. this may be causing your display issues.
