If your 2015-2020 Ford Falcon is struggling to start, especially in cold weather, or stalling while driving, it may be due to a failing fuel pump relay.
You might notice your engine cranks without firing, similar to an empty fuel tank scenario. Unexplained battery drain when your vehicle is off is another symptom.
Temporary relief from starting issues may follow jump-starting due to higher voltage.
As you investigate these problems, you’ll want to explore the root causes and diagnostic steps to identify the issue and explore your repair options, which we’ll discuss further.
What You Need to Know
- A failing fuel pump relay in a 2015-2020 Ford Falcon may cause struggles to start the engine, especially in cold weather.
- The engine may crank without firing, similar to an empty fuel tank scenario, indicating relay failure.
- Unexplained battery drainage may occur even when the vehicle is turned off, pointing to a faulty fuel pump relay.
- Temporary relief from starting issues may follow jump-starting due to higher voltage, but the problem will persist.
Failing Fuel Pump Relay Symptoms
When your 2015-2020 Ford Falcon struggles to start, especially in cold weather, it may be a sign that the fuel pump relay is failing, causing the engine to crank without firing up.
You might experience starting difficulties, and the car may crank repeatedly without starting, similar to when the fuel tank is empty.
This relay failure can also lead to unexplained battery drainage, even when the vehicle is turned off.
If you’ve jump-started your Ford Falcon, you might’ve noticed temporary relief from the starting issues, as the higher voltage can momentarily improve the relay’s performance.
However, this is only a temporary fix, and the problem will persist if left unaddressed.
Furthermore, if your car stalls while driving, especially after prolonged use, it could be a sign that the faulty fuel pump relay is affecting fuel supply to the engine.
It’s essential to recognize these symptoms to address the issue promptly and avoid further complications.
Diagnosing the Fuel Pump Problem
To diagnose the fuel pump problem in your 2015-2020 Ford Falcon, you’ll need to follow a series of steps to identify the root cause of the issue.
First, check the fuel pressure using a gauge, as low pressure readings can indicate a failing pump or relay issue.
Next, listen for the fuel pump to prime when turning the key to the ‘on’ position; a lack of sound often points to a malfunctioning fuel pump relay.
Inspect the fuel pump relay for any signs of physical damage or corrosion, as these can disrupt the electrical flow necessary for proper fuel delivery.
Utilize diagnostic tools like an OBD-II scanner to check for any diagnostic trouble codes (DTCs) that may highlight faults related to the fuel pump or its relay.
Furthermore, conduct a visual inspection of the fuel lines and connections for leaks or damage, as these can also contribute to fuel delivery issues alongside relay concerns.
Repair and Replacement Options
Your Ford Falcon’s faulty fuel pump relay can be repaired or replaced, and the cost will depend on the extent of the problem and the labor involved.
If you’re not comfortable doing it yourself, a mechanic can diagnose and fix the issue. They’ll likely start with relay testing to determine the root cause of the problem.
Depending on the results, they may need to source a new OEM part to guarantee proper compatibility and functionality.
Repair options include soldering connections or replacing the relay entirely.
Costs typically range from $50 to $150, depending on labor and parts.
To guarantee safety during the repair process, it’s essential to disconnect the battery and relieve any fuel system pressure.
Having documentation of past repairs and maintenance for the fuel pump relay can also assist mechanics in diagnosing future issues more efficiently.
Regular maintenance checks can help identify potential relay failures early, avoiding more costly repairs associated with fuel delivery issues.
By addressing the problem promptly, you can get your Ford Falcon back on the road quickly and avoid more extensive damage.
Preventing Future Fuel Pump Issues
By taking proactive measures, you can substantially reduce the risk of future fuel pump issues in your Ford Falcon. Regular maintenance and good habits can go a long way in preventing problems down the road. Here are some steps you can take:
- Inspect and replace the fuel filter regularly to prevent clogs that can strain the fuel pump and its relay.
- Use high-quality fuel from reputable sources to minimize the risk of contamination that can lead to fuel system issues.
- Schedule routine vehicle inspections and diagnostics to identify potential problems early, especially with the fuel pump relay and associated wiring.
- Keep the electrical connections to the fuel pump relay clean and secure to prevent intermittent failures caused by corrosion or loose connections.
Whats more, stay informed about any recalls or service bulletins related to the fuel system of the 2015-2020 Ford Falcon to address potential issues proactively.
Monitoring Engine Performance
You’ve taken proactive steps to prevent future fuel pump issues; now it’s time to focus on monitoring engine performance, as a failing fuel pump relay can manifest in various ways.
Regular engine diagnostics and performance monitoring are essential to identifying potential problems early on.
Pay attention to any unusual noises from the fuel pump area, such as buzzing or whining, which may indicate relay or pump malfunctions affecting fuel supply.
Track starting issues, noting how often the vehicle requires multiple attempts to start, as this can signify a relay failing to provide sufficient power to the fuel pump.
Observe vehicle acceleration and responsiveness; if the engine hesitates or struggles to gain speed, it may be due to inadequate fuel pressure caused by a compromised fuel pump relay.
Keep an eye on dashboard indicators, especially the Check Engine Light (CEL), as its activation can signal disruptions in fuel delivery linked to relay failures.
