My car don't seems to start up., it shows a battery problem but charged and still didn't start up. it shows oil leak but add a little oil still didn't do any good. the oil is still good. when i usually start up the car. its like its going to died and it have couple of times. i messed with the battery and it started up again. but this time it just wont start. the radio, lights all work but when i ignited it, u hear it crank just not like "rhmm"( normally what u hear when you start up a car)
