Hi all. I have toyota corolla altis 1.6 SR, driven around 190000 km. Car was perfect. But I did routine maintenance a week ago by cleaning plugs, injector, air inlet, silencer etc in short full tuning.i also changed fuel filter,just fuel filter...NOW, I am facing starting issue.it is not starting on first self start, but I give it short self once, twice and then it starts on third self..Battery is perfect,new...self starter is perfect..can reflect from its sound...fuel pump was perfect before tuning..as per mechanic issue may be due to replacement of fuel filter..as the black pipe of fuel filter inside was difficult to install at the time of installation...can anyone plz help what could be the issue?
