| I have no audio system on my car.
I think my problem started right after I put some fucking shitty additive in the gasoline to "clean" my system.
After that the problems began.
I've changed the fuel pump(and all filters) but my mistake was that I have left the old check valve and have not replaced with the new one(it came with the fuel pump).
The old fuel pump was making a strange noise(not a smooth sound like supposed to). I have believed that the fuel pump it's defective so I've replace it.
After that the weird sound was still there. It is also possible that the return line to not work properly. |
