1. Faulty wiring: Check the wiring connections to the fuel pump to ensure they are secure and free from damage. A poor connection can prevent the pump from receiving power.
2. Clogged fuel filter: If the fuel filter is clogged, it can restrict the flow of fuel to the fuel pump, causing it not to turn on. Check the fuel filter and replace it if necessary.
3. Defective fuel pump driver module: The fuel pump driver module is responsible for controlling the operation of the fuel pump. If it is faulty, it can prevent the pump from turning on. Check the fuel pump driver module and replace it if necessary.
4. Faulty fuel pump: Even though the fuel pump is new, it could still be defective. Check the fuel pump and make sure it is properly installed. You may need to replace it with a new one.
5. Faulty inertia switch: The inertia switch is a safety device that shuts off the fuel pump in case of a collision. If the inertia switch is tripped, it can prevent the pump from turning on. Check the inertia switch and reset it if necessary.
6. Low fuel pressure: Make sure that the fuel tank has enough fuel.
