Fixing a car that cranks but won’t start can be a bit challenging, but here are some steps you can take to troubleshoot the issue with a free car:
1. Check Fuel Level:
Ensure that the car has an adequate amount of fuel. Sometimes, the fuel gauge may not be accurate.
2. Verify Battery Health:
Make sure the battery is charged and in good condition. Check for corrosion on the battery terminals, and clean them if necessary.
3. Inspect Spark Plugs:
Examine the spark plugs for wear and fouling. If they are old or damaged, consider replacing them. Clean or replace as needed.
4. Check for Spark:
Confirm if there’s a spark in the ignition system. Remove a spark plug wire, insert a spare spark plug, and crank the engine. If you see a spark, the ignition system is working.
5. Inspect the Fuel System:
Check the fuel pump and fuel injectors. Listen for a humming sound when turning the key to the “On” position (not cranking). If you don’t hear the sound, the fuel pump may be faulty.
6. Verify Air Intake:
Ensure the air filter is clean and not clogged. A restricted air supply can affect the air-fuel mixture.
7. Check Timing Belt/Chain:
If your car has a timing belt or chain, ensure it is not broken or slipping. A broken timing belt can lead to a no-start condition.
8. Examine the Ignition System:
Check the ignition coil and distributor (if applicable). If any components are faulty, they may need replacement.
9. Scan for Error Codes:
Use an OBD-II scanner to check for error codes. These codes can provide valuable information about potential issues with sensors or systems in the car.
Remember to approach each step carefully and, if needed, seek advice from experienced individuals or professionals. Always prioritize safety when working on or around a vehicle.
