Anyone knows what could be causin a hard start( long crank time) in the toyota altis when its warm?
If I park up and come back in an hour it doesnt start on the first turn.. but on the second turn it does.
I changed the spark plugs to NGK Iridium, checked the injectors and no leaking injectors were found, chwcked the battery and it was good, checkedthe coil packs and they were good..
I am thinking the fuel filter..
Any suggestions?
Thanks 
Most frequent reasons are fuel pump failing, fuel pump strainer and filter needs changing or less frequently fuel pressure regulator failing.
The problem maybe that the fuel delivery system has lost its ability to hold delivery pressures and is a precursor to fuel delivery break-down.
You may find your first start in the morning or long periods whilst parked requires more cranking than normal and when operating during the day things get a little better.
