The reasons for difficulty in starting a hot engine include ignition coil breakdown, poor thermal stability of internal electronic components in the ignition module, damaged carbon canister solenoid valve, faulty intake air temperature sensor, etc. Below are the reasons for difficulty in starting a hot engine: Fuel injector leakage: The more severe the fuel injector leakage, the richer the air-fuel mixture becomes. Damaged carbon canister solenoid valve: During hot engine starts, fuel atomization is normal and additional fuel vapor is not needed. If the carbon canister continues to supply fuel vapor to the intake tract, it will result in an overly rich air-fuel mixture. Intake air temperature sensor: The function of the intake air temperature sensor is to adjust the fuel injection quantity. A faulty intake air temperature sensor can cause issues.

What are the reasons for the high fuel consumption of the Kia Soul?

There are three main reasons for the high fuel consumption of the Kia Soul. Below is a detailed explanation of these three reasons: 1. Abnormal tire pressure: If you notice that the vehicle's coasting distance is significantly reduced during driving, you should check whether the tire pressure meets the standard. If the tires are underinflated, fuel consumption will also increase. It is advisable to inflate the tires properly in a timely manner. 2. Tire wear: Check the degree of tire wear. If the tires are severely worn, slipping will frequently occur, increasing fuel consumption. New tires should be replaced when necessary. 3. Bearings and braking system: If abnormal noises are detected from the wheels during driving or starting, the bearings and braking system should be promptly inspected for faults. If the wheels do not rotate normally, it will affect the vehicle's speed and increase fuel consumption.
