I have a toyota vitz 2007 (old shape) model:
Dear Pakwheelers hope u all are fine..
I am facing these issues for nearly a month:
1.The car takes a long time to start (5-7 sec) after it is idle for 7-8 hours.
2.When the cars starts (after 1 min or so) I hear an annoying sound (goouuuuuunnnn) form the rear.( The sound comes from fuel pump).
The fuel filter and pump was changed at 31000 kms..Now it is 34600kms.
I went to the Totota capital motors to get these issues resolved..
They changed the oil,oil filter,plugs,air filter, thoroughly cleaned the fuel pump.
There is a very aged mechanic named " Muhammad Anwar" at toyota capital motors. He told me to run the car for few days and check whether the problem has been resolved or not..I also asked that whether the throttle body needs cleaning or not..He checked it and said "NO there is no need to clean it the condition is normal.
When I came home and tried to start the car after 9 hours the problem still prevails. There is nothing displayed on the Speedometer regarding the checking of engine or any other electrical failure.
I do not think that the problem will be resolved automatically after few days..
One thing more i use high octane and always get my car filled from F-6 Caltex. The avg km/l is 12..Before 2 moths it was 16 km/l on normal isloo roads.
