Car Will not start
Attempts to turn over, then makes a 'brrrrp' sound. What do I check?
sharihinkel could be a bad battery, not properly grouneded engine bolack or a bad starter. As blanemanis suggested, either fully charge your battery, or if it is relatively old, have it checked and replace it as necessarry. Once you have a known good battery, see if the engine then turns over properly. If it still does not, check your starter since it may draw to many amps because of a short or may have mechanical issues with the starter drive.
The problem most likely seems to be the battery, as other contributors have pointed out. The most surefire way to check if it indeed is a battery problem would be to use a multimeter and check the battery's voltage. It should be at around 12.6 V. In this case, simply jump start the car and let the alternator charge the battery up. Once you start it up, turn on the headlights, heating, radio, and anything else that uses battery power. If you get a 'check battery' light or the engine stalls, then you know it's most likely a problem with your alternator.
