Trick the Car Computer by Accelerating
In some cases, the electronic control module (ECM) won’t let a car start because of a bad coolant temperature sensor. This can be bypassed by sending fuel through the fuel pump. Press down on the accelerator pedal before turning the key to start the engine. This will engage the fuel pump, sending fuel to the engine, thereby fixing the coolant temperature sensor issue.
Tap the Battery Terminals
Tapping the battery terminals is a simple trick that can get your car started when the battery seems completely dead. Try wiggling a battery terminal into a new position to give the weak battery a better connection.
Start the Car in Neutral
This trick applies to cars with an automatic transmission since manual transmission cars always need to be started in neutral. Moving the gear stick could establish an electrical connection inside the car’s neutral safety switch.
Use Soda to Get Rid of Corrosion
If you see a white, blue, or green substance on a battery cable or terminals, corrosion is the likely issue causing your dead battery. Corrosion prevents a dying battery from properly conducting the electricity needed to start a vehicle. Get rid of battery cable corrosion by applying a fizzy drink like Coke or another soda.
Apply Baking Soda to Remove Corrosion
Baking soda is another effective way to remove corrosion from battery terminals. Make a paste with baking soda and water, apply it to the terminals, let it sit for a few minutes, then rinse it off with warm water.
Smear On Petroleum Jelly
After cleaning the battery terminals, apply a thin layer of petroleum jelly. This will prevent future corrosion and improve the connection between the battery and the terminals.
Drop Two Aspirin Tablets Into Each Battery Cell
Aspirin can be used to revive a dead car battery. The acetylsalicylic acid in aspirin combines with the sulfuric acid in the battery to produce one last charge.
Use the Epsom Salt Trick
Epsom salt can also help revive a dead car battery. Dissolve about an ounce of Epsom salt in warm water and add it to each battery cell.
