A bad alternator may kill the battery, but the alternator is part of the charging system, not the starting system.

Dude, have it towed to a shop, it's your fuel pump

I'm afraid you might be right.

Are you sure you hooked the jumper cables up to the correct ears?

What type of car were you using to jump and what type of car were you jumping?

Beware the cheap set of jumper cables, too.

So far it sounds like a failing starter motor or a bad/corroded ground connection at the battery.

That's my guess too. I generally categorize failure to start problems into 3

So what you have is an electrical issue, not a fuel delivery issue. You're not

Yup, pull the negative terminal off and bang it against something and see if any corrosion comes out, my

Check your battery terminals and cables. Take them off and clean with a terminal

If you want to isolate if it's the battery, jump it this way.

You could also swap out the battery with another car but I'm too lazy

You can do that, but don't run a car very long without the cables hooked to

Very true. As long as the jumper cables are connected they should be ok.

Haven't tried that before.... makes sense though. Thanks for the idea!

I had never heard of a dead battery interfering with the ability to jump

Troy McClure

A dead battery will suck the life out of the jumping

I knew that about dead batteries... some just truly die and a jump won't cut it.

No noise most of the time. Once in a while it will sound like it starting to

I think it's just a power supply issue then.

So assuming it is not the battery, that is what my 06 Honda Accord did before the starter went out.

It's your alternator. Take it to the shop.

It absolutely can. Let me tell you the story of my 86 Corolla

I think it might be my battery cables. They look terrible.

If you're handy then it'll only set you back $20 and about 30-45 minutes.

Cheap jumper cables have caused more bad diagnoses and wasted time than most people will ever admit.

Usually, the end is all you need to replace. Depending on the car, cables can be quite pricey and difficult.
