Engine Cranks But Won't Start: If the fuel pump is not installed properly, it might not deliver an adequate amount of fuel to the engine. As a result, you may experience issues with starting the car, and the engine can crank without turning over.
Engine Stalling or Surging: An improperly installed fuel pump could lead to inconsistent fuel delivery, resulting in sudden stalling or surging of the engine while driving.
Low Fuel Pressure: You can verify the fuel pressure using a fuel pressure gauge. A fuel pump that is not installed correctly might result in low fuel pressure, hindering sufficient fuel delivery to the injectors.
Fuel Leaks: Check the area where the fuel pump is installed for any visible fuel leaks. A faulty or improperly sealed fuel pump can lead to fuel leakage, which is dangerous and can also affect the performance of your vehicle.
Abnormal Sounds: If the fuel pump is not secured or installed properly, you might notice unusual noises coming from the fuel tank area, like a whining, buzzing, or clicking sound.
Check Engine Light: While various issues can cause the check engine light to come on, an improperly installed fuel pump can also trigger it. You can connect the car's diagnostic tool or get the codes read by a technician to determine if the issue is related to the fuel pump.
If you suspect that your fuel pump may not have been installed correctly, it's crucial to consult a qualified mechanic or automotive professional. They can diagnose the actual problem and perform the necessary adjustments or repairs to ensure that your fuel pump is functioning correctly and your vehicle runs smoothly.
