Q: occasional starting problems

asked by on

sometimes car wont start. lights on dash lights up but does not swing over and sometimes it has a grrr sound when trying to start and then it does nothing. had fuses, battery, starter checked. ABS box burnt (speedo ect wasnt working). i had it repaired. not sure if it could be a loose wire, spark plug or maybe battery related. i havent changed battery. the windows lights ect is working fine, so im not too sure about the battery. any idea what could be causing for it to sometimes not start. car went for service on 16 Aug 2016.

Hi and thank you for contacting YourMechanic. Two things come to mind - first: the battery could still be the issue. When the battery was tested, if the voltage was the only tested it could show good - at least 12.5 volts (13.5 -14.5 show full charged). The issue could still be that the cold cranking amp is not there. There could be a dead cell which will allow the battery to operate sometimes and then act like a dead battery at other times. Get the cranking amp of the battery tested. If there is a dead cell or if the cranking amps do not test up to spec, the battery will have to be replaced. The second thing that comes to mind is having a poor/loose ground. The number one ground issue is corrosion. With corrosion you will get resistance which in turn will not allow full voltage/amp to be available during the starting process.
