I just put new alternator and took the battery to get recharge at autozone it sat for a day try to get in and start but it only turns over but when I put the jumper cables to my car it start right up
My ranger turns over but doesn't start on 1999 Ford Ranger
Ckeck cable connections first, if ok have the battery load tested and all cells checked with a hydrometer! Sounds like a battery problem but possible parasitic load. Until tested as suggested,, there is NO way to know!!
