2003 mazda tribute, occasionally won't start. fuel pump replaced about 1 month ago. bad starter?


Many batteries may only last around three years. Check battery voltage at rest before starting. Any voltage in the low 12v range may be a sign of a faulty battery.If low voltage present, then perform a parasitic drain test:1) Disconnect battery POSITIVE terminal and connect ammeter in series, between battery positive terminal and positive lead.
DO NOT START THE VEHICLE!!

2) With all vehicle doors closed, alarm off, lights off, radio off, and all other accessories off, wait for around 20 minutes and then read the ammeter. A healthy system should read about 0.03 amps and little more. If reading more, then the vehicle could be suffering a parasitic amp drain, and you will need to locate this issue.


3) Reconnect battery when finished.


If no major parasitic drain present, yet low battery voltage then:


4) With vehicle started, check the voltage charge from the alternator. Connect voltmeter to battery terminals and take reading. A healthy system should be charging in the range of 14volts or down to around 13.5 volts. If reading around 12 volts only, then check and replace alternator.

What is draining my car battery?


sounds like perhaps it is time to purchase a newer car and let that one find a new home . our daughter had a problem like this and after much expense was told to unhook every thing electrical she could . ended up being the radio/stereo in the trunk.

I had a similar problem, 2003 530i, but only while the alarm was active. The culprit was a bad hood switch that was making intermitent connection.

2001 530i battery drain/alternator question


first off never never never trust a tow truck driver they are idiots, it takes a BMW 15 mins to go into a sleep mode before a draw can be mesured, as for the dealership they should have caught that using the Midtronics batt/alt tester that is standard from BMW 2.5 years for a batt replacement is reasonable especially in a BMW based on the high demand on the electrical system, I just replaced an alt on an M54 enginge just today so they do go bad, have them give you a print out from the midtronics with your VIN on the printout showing your alt is bad and what the batt is.

My 2004 530i won't start.


If you hear a mechanical hum then its either something with the starter or the battery. Charge your battery and see if its just a little too weak to turn the engine over. If that doesnt fix it, then you might have to replace the starter. Unless there is a serious mechanical issue, your engine shouldnt be the reason the starter can't get it to turn over.
