    Default 2-3 seconds longer crank times after Vitz is parked for 6 hours.

    Hi,

    I've a 2010-model, 1L Vitz. Since the past week, if I leave the car parked for six hours or so, the engine/ignition cranks two to three seconds longer when starting for the first time. Last week I added four litres of hi-octane on top of super. However, I noticed the longer crank time once before adding the hi-octane.

    What could be the issue? It runs fine otherwise. There are no other perceivable issues. The battery is three-years old. Is it an early sign of battery going down? It works fine otherwise.

    I found one other thread here with a similar problem, but I couldn't find anything conclusive in the discussions.

    Any help will be greatly appreciated.

    Thanks.

    Lets come to basic things first, have you checked your plugs and plug wires? If engine is cold, then it requires higher current to ignite the fuel, if spark is not powerful enough, then you might face this problem.

    its very normal, its called fuel pressure bleed down.

    Thanks.
    plz try this
    turn the key to ON Position (dont start) & wait for 3 seconds then turn it back to OFF position after that start the car.

    it will allow the fuel pump to build the pressure prior cranking.

    If some thing is related to fuel pressure bleeding stuff then it will start at once otherwise u need to clean the Fuel filter, Fuel Injectors & spark Plugs

    just turn on ignition don't crank. 3 or 4 times,, turn on and off. . fuel pump runs fuel. then you crank easy and engines fires up fast. I do this with drift cars because I use them after weeks or month.

    toyotas dont run the fuel pump unless you crank the engine, the circuit works once while cranking and then latches from the MAF fuel circuit switch. That is why when these are brand new the fuel system is primed from the fuse box.

    The newer D4-D engines do run the intank pump and the high pressure pump in order to build the required start pressure

    Hi guys,

    Thank you for your valuable replies, @Xulfiqar, @levin, @hameeds01 and @sirdneo. I wasn't aware of the concept of fuel pressure bleed. Toggling the ignition a couple of times before cranking did help with decreasing the crank time. What I have noticed is that, the crank time only increases when I add hi-octane into fuel tank. But after reading your replies and experimenting myself, I am no longer worried about it.

    Many thanks.

    Cheers,
    Ayaz
