I gave someone a jump now my car won't start. When you turn the key everything comes oh but won't turnover. Could it be the 120a fuse on battery.

 

Hi Bill. Welcome to Maxima.org.

We try to help everyone who has a problem, but in order for that to happen, you have to give us some information besides car won't start. With all the different years of cars, the answer to your question can be both yes and no.

Ya gotta give us more info. Year, model, transmission, mileage is the bare basics. Without this, your chances of getting an accurate answer is slim to none.

If you are interested in working on your own car, you can get the service manual here:
