Why will my 2002 Chevy Impala not always start?

Answer 1

This a very vague question and there are a number of reasons why your car might not start. If it doesn't start and you have to jump it, then it starts up fine for a while and then doesn't work again its probably your battery. If, while you're driving, you accelerate and your headlights get brighter then you slow down and they dim and eventually your car sputters out and won't start you have a bad alternator. If you have to turn the key a couple times to get it to start check your spark plugs and/or wire connections. Hope this helps
