Accord 9 generation 2.4 can't be started without sound.

The reason for this is the following：

1. Analysis may be caused by excessive carbon deposition in throttle, idle motor, air intake, air intake valve and combustion chamber. If there is too much carbon deposit in the combustion chamber and the fuel nozzle, the carbon deposit will absorb a certain amount of mixed gas during cold start, which will lead to too thin mixed gas during start-up and make it difficult to start.

2. Or because there is a problem with the carbon canister or the solenoid valve of the carbon canister, the mixed gas is too thick when starting, which will also lead to difficulties in starting. It should also be noted that another possibility is that the constant pressure performance of fuel in the electronic control system is poor and the fuel pressure is low, which leads to poor atomization of fuel injection and is not easy to start.

3. Give it a try. Open the key door until the instrument light is on and the sound of the oil pump is heard. After the sound is over, close the key door, and then repeat the above operations until the sound of the oil pump is no longer the sound of sound, and then step on the accelerator to start. You should be able to hit it at once.
