Hard starting TOYOTA Yaris Hatchback (_P9_)

A faulty fuel pump or clogged fuel filter can reduce the fuel pressure, making it hard for the engine geometry dash to start. If the fuel injectors are dirty or malfunctioning, they may not be supplying enough fuel to the engine during startup.

Thank you for providing very useful information!

Reduced fuel pressure, caused by a malfunctioning fuel pump or a blocked fuel filter, makes starting the engine difficult. Inadequate fuel supply to the engine during beginning could be caused by unclean or defective fuel injectors.

If the fuel pump is weak or the fuel filter becomes restricted, the incredibox engine may experience low fuel pressure and struggle to start; likewise, contaminated or failing injectors can prevent the proper amount of fuel from reaching the combustion chamber during ignition.

There could be a problem with the fuel pump, fuel filter, or fuel injectors, leading to insufficient fuel reaching the engine during startup drive mad 3.

If the CKP sensor is slow to signal, the ECU won’t trigger spark and fuel immediately.

Symptoms

Long crank, especially when hot

Sometimes random stalling

No check-engine light in many cases google

Based on experience with this engine:
Replace fuel pump + strainer (biggest success rate).
Clean throttle body and run fuel system cleaner.
Replace crankshaft position sensor if the issue is intermittent.
Check battery and starter. Fun with Geometry Dash
Replace spark plugs (engine idles better immediately).
