I got an 89 Laredo and I went to start up to drop off my gf and when I cranked it over it went really slow but started right up. So I shut it off waited a second and tried starting it again and it won't turn or even click all it does is make his humming sound when you turn the key to try to start it what I also notied is when turn the key my temp gauge goes all the way to the right. Can anyone help?

 

sounds like battery i would check the bat terminals for corrosion and make sure there tight first thing

 

I just checked those and the battery is probably 5 months old

 

Also just tried to jump start it still nothing

 

do the head light work

 

If your bat is that fresh and good, could be bad ground. I've had more than one ground wire (battery to block) fail on dif vehicles over the years. If your bat looses that ground it could have lost the charge as your alternator wouldn't be able to recharge with an incomplete circuit. When it wouldn't go with a boost it seems like an inclomplete circuit. 2nd thing to check is the positive lead to the starter, is it a good line?

 

Check this fuse under the hood. Check the neutral safty switch.

 

Well figured it out it's my starter motor my solenoid got stuck banged on it couple times started up

 

Thanks alot for the help anyway appreciate it very much
