"This doesn't make clicks inside I've even connect it direct From the battery but the fuel does not flow out, could it be that it has burn? Engine refuses to start."
-------------------------------------------------------------------------------------------------------
If you're experiencing a situation where your engine refuses to start and you've confirmed that there are no clicking sounds or fuel flowing, there could be several potential causes. One possibility is that the fuel pump or fuel injectors are faulty or not receiving power. This could be due to a burned fuse, a malfunctioning relay, or a problem with the wiring.
Here are a few steps you can take to troubleshoot the issue:
1. Check the fuel pump fuse: Locate the fuse box in your vehicle and inspect the fuse related to the fuel pump. If the fuse is blown, replace it with a new one of the same rating. However, a blown fuse indicates an underlying problem that may require further investigation.
2. Examine the fuel pump relay: The fuel pump relay controls the power supply to the fuel pump. Consult your vehicle's manual or a wiring diagram to locate the fuel pump relay. Check if it's functioning correctly by swapping it with a similar relay from another system in your vehicle. If the engine starts after swapping the relay, the original relay may be faulty and needs to be replaced.
3. Inspect the wiring and connections: Examine the wiring harness and connections associated with the fuel pump and fuel injectors. Look for any signs of damage, loose connections, or corrosion. Repair or replace any damaged wiring or connectors and ensure they are properly connected.
4. Test the fuel pump: If you have access to a fuel pressure gauge, you can test the fuel pump's functionality. Connect the gauge to the fuel rail or fuel line and turn the ignition on without starting the engine. The gauge should display the correct fuel pressure for your vehicle. If there is no pressure or it is significantly lower than the specified value, the fuel pump may be faulty and require replacement.
If you're unable to diagnose and resolve the issue on your own, it's advisable to consult a qualified mechanic or contact a professional roadside assistance service for further assistance. They will have the necessary tools and expertise to identify and fix the problem with your engine.
We look forward to your comments... 😉
