Hi Mate, I have replaced the fuel filter in my Toyota Corolla 2003 conquest. It's the ryco fuel filter(after market). There is problem came up after replacing the filter. The car does not start in first crank, start in second one or keep cranking till start. I have taken to the mechanic and he put new O rings. The problem is still there so it's still taking long crank to start in first time. Any suggestions which can prevent the problem. Thanks for the reading
