How to Fix Starter Issues on Your 2020 RAM 1500
This guide focuses on addressing starter problems specifically in the 2020 RAM 1500. Starter issues can be frustrating, leaving you stranded and wondering what went wrong. Many owners have faced similar challenges, often finding the solution in unexpected places. As one owner shared: "Your symptoms scream poor connection(s) somewhere 99/100 times... Temperature affects both fastener clamp load & terminal contact (metal contracts when cold) which in turn affect the ability to carry load." (source) This guide will help you diagnose and potentially fix the starting issues with your truck.
Symptoms
The symptoms of a failing starter system in your 2020 RAM 1500 can manifest in various ways. You might experience a complete failure to start, where turning the key or pressing the start button results in nothing happening. This can be accompanied by the dashboard lights illuminating as normal, leading you to believe the battery is functioning correctly.
Another symptom reported by owners is an intermittent starting issue. In these cases, the vehicle might start fine sometimes, but then fail to start at other times, often without any discernible pattern. This intermittent behavior can make it challenging to diagnose the root cause. As one owner pointed out, sometimes the truck won't turn over at all.
Some owners have also noticed that temperature seems to play a role. Cold weather conditions appear to exacerbate the problem, making it more difficult to start the truck when the temperature drops. This might indicate an issue related to connections, as metal contraction in cold weather can affect their ability to conduct electricity effectively. This is why you need to check all electrical connections.
Finally, a less common but still possible symptom is related to the gear selector position. Even if your truck is in Park, a faulty gear selector might cause the system to think it's in another gear (like Reverse), preventing the starter from engaging.
Most Likely Cause
Based on owner reports, the most likely cause of starting issues in the 2020 RAM 1500 is poor electrical connections. As "CurrentlyatBDC" succinctly put it, a poor connection is the culprit 99/100 times. Temperature changes significantly affect these connections.
The issue often stems from loose or corroded connections at the battery terminals, the Power Distribution Center (PDC), the starter itself, and related ground wires. These connections can weaken over time due to vibrations, exposure to the elements, and the natural loosening of fasteners. The "snow chief package" might play a role in the battery performance.
When the connections are compromised, the electrical current flow to the starter is restricted. This reduced current can prevent the starter from engaging properly, leading to the symptoms described earlier. Moreover, the truck uses a special package on its battery.
Furthermore, temperature fluctuations can exacerbate the problem. As metals contract in cold weather, the clamping force of fasteners decreases, further reducing the contact area at the connections and hindering current flow. This explains why some owners experience more starting issues during cold weather.
How to Diagnose
Diagnosing a starting issue in your 2020 RAM 1500 requires a systematic approach to identify the root cause. Here's a step-by-step process:
-
Visual Inspection: Begin by visually inspecting the battery terminals and connections for any signs of corrosion or looseness. Clean any corrosion with a wire brush and ensure the terminals are securely tightened. You will need gloves and a wire brush for this.
-
Battery Test: Use a multimeter to check the battery voltage. A fully charged battery should read around 12.6 volts. If the voltage is significantly lower, the battery might be weak and unable to provide enough current to the starter. A load test can also be performed to assess the battery's ability to deliver current under load. You will need a multimeter for this.
-
Connection Check: Inspect all electrical connections related to the starter system, including those at the PDC, the starter itself, and any ground wires. Ensure these connections are clean and tight. Pay close attention to any connections that appear corroded or damaged. You will need a wrench for this step.
-
Gear Selector Test: Try shifting the gear selector from Park through Reverse to Neutral and back to Park. This can help rule out a faulty gear selector switch as the cause of the starting issue. Sometimes the gears are off.
-
Starter Relay Test: Locate the starter relay in the PDC and test it using a multimeter. You can also try swapping it with another identical relay in the PDC to see if that resolves the issue. This will require a multimeter.
-
Video Recording: If the problem is intermittent, try recording the starting process on video. This can provide valuable evidence to a mechanic if you are unable to resolve the issue yourself. A smartphone is perfect for this.
Step-by-Step Fix
If you've diagnosed the starting issue to be related to loose or corroded connections, here's how you can attempt to fix it:
-
Gather Tools and Materials: You'll need a wrench set, a wire brush, battery terminal cleaner, dielectric grease, and possibly replacement battery terminals if the existing ones are severely corroded.
-
Disconnect the Battery: Before working on any electrical connections, disconnect the negative battery terminal to prevent short circuits.
-
Clean Battery Terminals: Use a wire brush and battery terminal cleaner to thoroughly clean the battery terminals and cable clamps. Remove all traces of corrosion.
-
Tighten Battery Terminals: Ensure the battery terminals are securely tightened. If the terminals are damaged or corroded beyond repair, replace them with new ones.
-
Inspect and Clean Other Connections: Locate and inspect all other electrical connections related to the starter system, including those at the PDC, the starter itself, and any ground wires. Clean any corrosion and ensure the connections are tight. "If you/your dealer hasn’t already, every connection from the battery to the PDC to the starter B+ feed needs to be tightened, as do related grounds, PDC connectors checked & reseated as well," as one owner suggests.

-
Apply Dielectric Grease: Apply a small amount of dielectric grease to all electrical connections to prevent corrosion and improve conductivity.
-
Check Ground Wires: Ensure that all ground wires are securely attached to the frame or engine block. Clean any corrosion and tighten the connections.
-
Reconnect the Battery: Reconnect the negative battery terminal.
-
Test the Starting System: Try starting the truck to see if the issue has been resolved.
-
Gear Shift Test: Shift gears to see if that fixes the starting issue. "Next time it happens try shifting it from Park through Reverse to Neutral then back to Park again. I chased starter issues on my truck but it turned out that something is wonky with my gear selector." as stated by another owner. (source)
