Startup delays can be caused by:

Weak 12V battery, which affects the hybrid system’s power-up process.
Hybrid system malfunctions, such as issues with the inverter o r electric motor.
Fuel system problems, like clogged fuel lines o r weak fuel pumps.

Diagnosis: A diagnostic scan tool OBD-II can identify the issue.
Solution: Check the 12V battery regularly and replace it every 3-5 years. If the issue persists, seek professional assistance to check the hybrid system and fuel components.
