My truck died on me in the parking lot. I changed the battery because it didn't want to charge when I was trying to jump it. Then I drove for a little bit and then the truck died on me again. Thinking it is my alternator, I replaces my alternator and it is still doing the same thing. When on idle my RPMs are about 500-600 and the battery gauge is under 14. I am thinking that it might be my idle sensor but I have no idea.

 

Is the check engine light on? If it is it will lead you in the right direction.

 

No it isn't
