2020 Ford F-150 Starter Problems? Here's How to Fix It

How to Fix Starter Issues

Experiencing starter problems with your 2020 Ford F-150 can be frustrating. The vehicle might not start, or you might hear unusual noises when you turn the key. Identifying the symptoms early can help you diagnose the issue and get it resolved quickly. As one owner shared: "It worked 100% normal for 2 days. This evening I went to start and I got lights on the dash for 8-10 seconds then all lights go dead and when I turn the key to start, there is a slight noise from the starter."

Symptoms

Several symptoms can indicate a starter issue in your truck. One of the most common is a no-start condition, where the engine fails to crank or turn over when you turn the ignition key. This can be accompanied by a clicking sound coming from the starter motor.

Another symptom is unusual noise during starting. Some owners have reported a slight noise from the starter when attempting to start the engine. Others may hear a rattling noise, which could indicate a loose starter motor or a worn-out component. The presence of noise can be intermittent, making it difficult to diagnose.

Corrosion on the battery terminals or starter connections can also contribute to starting problems. Check for any signs of corrosion, such as white or bluish deposits, which can impede the flow of electricity. Loose connections can exhibit similar symptoms. As one owner reported: "If battery is good, check terminal connections(if corroded or loose, clean and tighten). If still no start, most likely starter solenoid or starter itself" (demoman45).

In some cases, a check engine light may illuminate on the dashboard. While a check engine light can indicate numerous issues, it's essential to retrieve the diagnostic trouble codes (DTCs) using an OBD-II scanner to determine if any codes are related to the starting system. The DTCs can provide valuable clues about the source of the problem.

Most Likely Cause

Based on owner reports, a vacuum leak is a plausible cause related to starting issues in this F-150 model year. A vacuum leak can affect the engine's air-fuel mixture, making it difficult to start. While not directly related to the starter itself, the engine might struggle to start due to the incorrect mixture, causing the starter to work harder or fail to engage properly.

An intake leak can create similar issues. When there is a leak in the intake manifold or related components, it can affect the amount of air entering the engine. This, in turn, can disrupt the combustion process and cause hard starting or no-start conditions.

The starter motor itself, or the starter solenoid, could be the issue. The solenoid is responsible for engaging the starter motor and providing it with power. If the solenoid fails, the starter motor won't engage, preventing the engine from cranking. As one owner pointed out: "you can use a screwdriver across the big studs to check the starter function.. that should make the starter engage.." — waynep712222.

How to Diagnose

Diagnosing a starter issue involves a systematic approach to identify the root cause. Start by checking the battery voltage using a multimeter. A fully charged battery should read around 12.6 volts. If the voltage is significantly lower, the battery may be weak or discharged.

Inspect the battery terminals and starter connections for corrosion or looseness. Clean the terminals with a wire brush and tighten the connections to ensure good contact. Also, trace the positive battery cable to the starter.

Next, perform a starter voltage drop test. Connect the multimeter to the starter motor while someone attempts to start the engine. If the voltage drop is excessive, it indicates a problem with the starter motor or its wiring. The vehicle may have a corroded starter.

If the battery and connections check out, test the starter solenoid. Locate the solenoid (typically mounted on the starter motor) and use a screwdriver to jump the two large terminals. This bypasses the solenoid and directly powers the starter motor. If the starter engages, the solenoid is likely faulty. If the starter does not engage, inspect the starter itself.

Step-by-Step Fix

1. Gather necessary tools and parts: You'll need a socket set, wrench set, multimeter, wire brush, replacement starter (if necessary), and safety glasses.

2. Disconnect the battery: Disconnect the negative terminal of the battery to prevent electrical shorts.

3. Locate the starter motor: The starter motor is typically located on the engine block, near the transmission.

4. Remove the starter wires: Disconnect the wires connected to the starter solenoid. Note their positions for reinstallation.

5. Remove the starter mounting bolts: Use a socket wrench to remove the bolts securing the starter motor to the engine block.

6. Remove the starter motor: Carefully remove the starter motor from its mounting location.

7. Inspect the starter: Check the starter for any visible damage, such as broken wires or a cracked housing.

8. Test the starter (optional): Connect jumper cables to the starter motor to test its operation. If the starter doesn't engage, it's likely faulty. As one owner shared: "If it were me I’d try throwing a breaker bar on the crank pulley to try and move the flywheel just a little. Then give the starter a good wack or two." — LastEntertainment684.

9. Install the new starter (if needed): Install the new starter motor in the reverse order of removal.

10. Reconnect the battery: Reconnect the negative terminal of the battery.

11. Start the engine: Start the engine to verify that the starter motor is functioning correctly.

Real Owner Costs

The cost of repairing a starter issue can vary depending on the cause and whether you choose to DIY or hire a professional mechanic.

DIY: If you decide to replace the starter motor yourself, the cost of the part can range from $150 to $300, depending on the brand and quality. You'll also need basic tools, which you may already have. So, the total cost could be around $200 to $350.

Professional Mechanic: If you prefer to have a mechanic diagnose and repair the issue, expect to pay for labor in addition to the cost of the parts. Labor rates vary by location, but typically range from $100 to $150 per hour. The total cost could be around $400 to $700 or more, depending on the complexity of the repair.

As a real-world example, one owner reported spending $250 on a replacement starter motor and another $300 on labor to have it installed. This demonstrates the potential cost savings of DIY repair.

Prevention

Preventing starter issues involves regular maintenance and inspections. Keep the battery terminals clean and tight. Check for any signs of corrosion and clean them with a wire brush if necessary. Consider using a battery terminal protector to prevent future corrosion.

Have the battery tested periodically to ensure it's in good condition. Replace the battery if it's weak or nearing the end of its lifespan. Also, avoid excessive cranking, which can overheat and damage the starter motor. Start your truck within a reasonable time frame to prevent unnecessary wear and tear on the starter.

Regularly inspect the starter wiring for any signs of damage or fraying. Replace any damaged wires to prevent shorts or other electrical issues. Properly functioning grounds are important as well. As one owner shared: "Truck fires right up regardless of how hot it is out side or how long the motor has been running and I live in the Deep South. I really underestimated how important a good ground is and the importance of new cables." (Kevo80).
