hey everyone i have been able to start my car no problem but the other day my car wont start. everything works fine lights, radio, dash etc. the car starts when i get a jump from another car and it would work for a couple days then it wouldnt start again. today i bought a new battery and put it in and still no luck starting but it starts when i get it jumped. any ideas? evos my dd and i need help with this thanks guys.

 

Try checking your grounds. Since everything else works it may not be that though but I'd still check them.

 

Try cleaning the connectors at the battery posts.

 

ive checked both and cleaned the post nothing happend. any other ideas?

 

Alternator

 

Starter relay

 

If Barneyb's input doesn't fix it I'd say starter relay as well.

 

When it won't start check the battery voltage. I doubt a car would run a few days off just battery power unless it's short trips not using the lights much. The easiest way to test your alternator is to jump the car and while it's running disconnect the negative battery cable. If it dies, the car is running off battery, if it runs, the alternator is keeping it running

 

Do you have a voltmeter? You need to put the positive lead to the starter solenoid, I believe is the black and yellow wire or the smallest wire to the solenoid, negative to motor . Have someone crank the motor to see if you have 12v at the solenoid. If so, you need a starter. You may also put the leads across the Batt. to see if there is 14.5v when the motor is running, quick check to see if the alt. is putting out. GL.

 

i would say the alternator... cause if your battery is holding a jump then its not the battery and nothing is recharging it so it will run out of juice. the dash and what not will work, but doesnt have enough to start the car. happened to my other car not to long ago and it was the alternator.

 

if it was the alternator wouldnt my car start when i put a brand spanking new battery?
