Ignition Switch Issues
The ignition switch is where you put the key. If it is broken, the car will not start. Try turning the key. If it feels loose, this might be the problem.
Check the Alternator
The alternator charges the battery. If it is not working, the battery will drain. Your Jeep will not start. If your lights dim when starting, this could be the cause.
Fuel Pump Failure
The fuel pump sends fuel to the engine. If it fails, the engine will not get fuel. Your Jeep will not start. Listen for a hum from the fuel pump when you turn the key.
Check the Spark Plugs
Spark plugs ignite the fuel in the engine. If they are old or dirty, they may not work. This can stop your Jeep from starting.
Cold Weather Effects
Cold weather can make it hard to start your Jeep. The battery may not work well in cold. Keep your Jeep inside a garage if you can.
Security System Problems

Transmission in Park or Neutral
If your Jeep is automatic, check the gear. It must be in Park or Neutral. If it is not, the Jeep will not start.
Clutch Problems in Manual Jeeps
Manual Jeeps need the clutch pressed to start. Make sure you press it all the way. If the clutch switch is broken, it may not start.
Inspect the Fuse Box
Fuses protect your Jeep’s electrical parts. If a fuse is blown, the Jeep might not start. Check the fuse box and replace any bad fuses.
Check for Corrosion
Corrosion can happen on battery terminals. This can stop power flow. Clean any corrosion with a brush and baking soda.
Look for Leaks
Leaking fluids can cause problems. Check under your Jeep for leaks. Fix any leaks to keep your Jeep running well.
Computer System Issues
Modern Jeeps have computer systems. Sometimes, they may have problems. This can stop your Jeep from starting. A professional can help with this.
