Car won't start unless jumped. Good battery and alternator.

Did you put a OEM alternator in? If not that's part of the issue,aftermarket alternators in Asian automobiles will back feed causing the charging system not to work.

It is OEM.

A Toyota alternator,not one from a parts store.

I got it off of a Toyota.

Put in battery with a little bit more cranking amps

Common Starter problem with this car. I would replace the copper contacts and plunger inside the starter. It's better to fix the OEM one (and cheaper) than to replace with an aftermarket one. Check this link: http://antares.co.nf/toyota-corolla/starter/

You got it off a Toyota??? Wow.

It's not the starter because it starts perfectly when I jump start it. And it's not the alternator either because the one on it has tested good.

Cjsras, the alternator I have on it is original. It is not aftermarket.

So you never replaced the alternator? and if you jump it,it will start?you put a different battery in it (not new) and it won't start with that either. Is all this correct?

I got the alternator from a parts car that I own. Battery too. The battery is still under warranty so I can always go get a new one if that's the case. But yes it will only start when jumped.

Thank you,Yes,please put in a new battery.That is were you need to start.

I will be back later with an update. We'll go from there.

I should be around.

Cjsras, I didn't get a new battery. However, I was able to get it to start a few times. And then it stopped turning. When I turn the key it'll either do nothing, click once, or click repeatedly until I stopped turning the key. Won't start again unless jumped. Any ideas?

It may be the starter. What do you think?

It sure sound like low battery voltage along with a bad connection at battery,starter or ground.If it was a ignition switch issue you wouldn't have power to have a click. Diffidently check all connections for tightness or corrosion.

If all connections look good then yes, replace starter or you can buy a plunger kit from Toyota for $10.00 or so.

The connections should be good. I completely redid the positive terminal as the people it was bought from had 2 wires tucked under a clamp on the terminal. I also check the connections on the starter and they seem to be good. I also tapped it with a hammer a couple times.

So Are you good?

I seem to have figured it out. It was having bad connection and it lost it, resetting the brain. So I plugged it in all good and tight and drove the hell out of it to give the brain time to relearn.

just reuse the alternator by removing the cutout (alternator rectifier) http://www.discountstarterandalternator.com/p/new-alternator-rectifier-fits-toyota-corolla-1- 8l-2-4l-2009-2010-2011-2012-2013/ your main alternator is soldered and this should be removed by soldering iron and refix with the new onw

I cannot believe every answer I read on this condition trying swapping out Parts you start by diagnosing with proper tools a cheap $5 voltmeter. But just from reading the problem it was obvious it was a connection because when the jumper cables were connected to the battery terminals the Jaws grabbing the outside of the terminals the car started. That tells you the connector on the inside portion which goes to the dead battery or dead car was not making a good connection clean and simple.

I have the same problem: my Corolla, current odometer reading at about 74,400 miles, needs a jump at every start of the day in the summertime. But in the wintertime while living without having snow around, it requires a jump at every stop. (For example: I drove about a mile to a grocery store - came out of the store - required me to use a jump- drove up to nearby gas station less than a mile down the road to get some gasoline - required me a jump - drove to the bank about a mile down - came out of the building - required me a jump). Yes, changed the battery with a new one. Purchased a new alternator and brought it to the mechanic, only to be told that no alternator replacement needed because it's still good. Had the mechanic to replace the negative battery terminal with new. Still the same. I am willing to have the positive terminal replaced, once the part has been located. But do not know if it will solve the problem. Other than this issue, never had an accident, my Corolla runs great. I love my Toyota Corolla.
