Hello everyone. The injection sound never stops when you turn the ignition on or off.This problem appeared after replacing the tps sensor. The relay has changed But the problem persists. Does the amount of fuel in the tank matter? Hypermotard796EU-2010
Do you mean the fuel pump sound? The fuel pump should run for 2-3 seconds at switch on then turn off until the engine turns over with the starter. If it is staying on either the relay is faulty or the connection to the ECU is being held low by either the wire shorted to earth or a faulty ECU.
