95 Jeep Cherokee crank no start issue fixed easy!!!

Introduction

This tutorial provides a step-by-step guide to diagnosing and fixing a crank no-start issue in a 1995 Jeep Cherokee. If your Jeep is cranking but not starting, this guide will help you identify common problems and provide easy fixes.

Step 1: Check the Battery and Connections

• Inspect the battery: Ensure the battery is fully charged. A weak or dead battery can prevent the engine from starting.

Examine battery terminals

• Look for corrosion on the terminals.
• Clean the terminals with a wire brush if necessary.
• Test the battery voltage: Use a multimeter to check if the battery voltage is above 12.4 volts.

Step 2: Verify the Fuel System

• Check fuel level: Make sure there is enough fuel in the tank.
• Listen for the fuel pump: Turn the ignition key to the "on" position (not start) and listen for a humming sound from the fuel tank, indicating the pump is working.
• Inspect the fuel lines: Look for any leaks or damages.
• Test fuel pressure: Use a fuel pressure gauge to ensure the pressure is within the manufacturer’s specifications.

Step 3: Examine the Ignition System

Check the spark plugs

• Remove a spark plug and inspect it for wear or fouling.
• Replace if necessary.

Test for spark

• Use a spark tester or reconnect the spark plug, ground it against the engine, and crank the engine to see if it sparks.
• Inspect ignition coils: Ensure the coils are functioning properly and replace any faulty coils.

Step 4: Inspect the Crankshaft and Camshaft Sensors

• Locate the sensors: The crankshaft and camshaft sensors are usually located near the engine block.
• Check for damage: Look for any visible signs of wear or damage.
• Test the sensors: Use a multimeter to check for proper voltage and continuity.
• Replace if necessary: If the sensors are faulty, replace them to restore engine functionality.

Step 5: Review the Engine Control Unit (ECU)

• Check for error codes: Use an OBD-II scanner to check for any stored error codes that could indicate issues.
• Clear codes: If there are codes, clear them and see if they return after attempting to start the engine again.
• Inspect wiring: Look for any broken or frayed wires leading to the ECU.

Conclusion

In this guide, we covered essential steps to diagnose and fix a crank no-start issue in a 1995 Jeep Cherokee. By checking the battery, fuel system, ignition system, sensors, and ECU, you can identify the root cause and take the necessary actions to get your Jeep running again. If problems persist after these checks, consider consulting a professional mechanic for further assistance.
