Fuel or Spark: The Two Vital Components

When your car cranks but doesn’t start, it usually means it’s missing one of two critical elements: fuel or spark to the spark plugs.

**Step 1: Checking Fuel**

1. **Starting Fluid Test**: Begin by checking if the issue is related to fuel. Grab a can of starting fluid, a readily available automotive product. Locate a spot near the air filter assembly where you can spray starting fluid, typically a hole or opening. Remove any sensors obstructing access and spray a small amount of starting fluid into the hole.

2. **Attempt to Start**: Try starting the car. If it starts but then quickly shuts off, it indicates a fuel-related problem.

3. **Check Fuel Pump**: Inspect the fuel pump fuse to ensure it’s not blown. However, fuel pump fuses are often intact, and the issue lies with the pump itself.

4. **Test Fuel Pressure**: To confirm a faulty fuel pump, turn the ignition key to the “on” position and attach a fuel pressure gauge to check for fuel pressure. If you don’t have a fuel pressure gauge, you can use a simple trick. Locate the fuel injector rail, usually near a large bolt. Use a socket wrench to crack open the bolt slightly. If no fuel pressure sprays out, it indicates a faulty fuel pump that needs replacement.

**Step 2: Checking Spark**

1. **Testing Spark**: If the car didn’t start when you used starting fluid, the issue may be related to spark. Begin by taking out one of the spark plug wires.

2. **Spark Plug and Jumper Cable**: Insert a spare spark plug into the removed wire. Next, take a jumper cable and connect one end to the spark plug and the other end to the negative terminal of the battery.

3. **Crank the Engine**: Crank the engine over while observing the spark plug. You should see a visible spark. If there’s no spark, it indicates an issue with the ignition system.

Possible Ignition System Issues:

– **Distributor**: In older vehicles, ignition issues often stem from a bad distributor, which may need replacement if it’s faulty.

– **Modern Vehicles**: Newer cars typically don’t have distributors; they utilize coil-on-plug ignition systems, where each cylinder has its own ignition coil controlled by the computer. If you lose spark in a late-model car, it can be more complex. Common issues include a faulty crankshaft position sensor, which may require replacement.

By following these diagnostic steps, you can pinpoint whether the problem lies in the fuel delivery system or the ignition system, helping you effectively address the issue and get your car running smoothly once again.
