Having a little trouble with my truck today. I went to start it up to head to class and she wouldn't crank. I had lights but no crank. I took the battery to the auto parts store and it tested good, so I got a starter to throw in. Old one was original to the truck anyways and I've been meaning to replace it for a while. After putting in the new starter, I'm still in the same boat. I can hear the fuel pump when I turn the key. I'm not sure where to go from here.
