Car cranks pretty long on occasions...around 50% of times when I try and start engine.
Does this often at both cold and warm starts...

Car's got around 86000 kms. Battery is new. I am thinking maybe something to do with either spark plugs, coils, or maybe injectors which are still originals...

Anyone got similar issues?
Any possible reasons for this?

Long crank time = faulty fuel pump or loss of fuel pressure causing the pump to crank longer to get enough pressure to the injectors.

Thanks dude. I was planning on changing the fuel pump. Will give it a change and see if it gets fixed.
