Why am I not getting any fire from my coil

Nate, it seems you're experiencing a frustrating issue with your Ford F-Series. Let's troubleshoot this together! Lack of spark from the coil can be caused by several factors. Here are some steps to consider:

1. **Wiring Connections**:

- Ensure that all your wiring connections are secure. Double-check the connections to the coil, distributor, and ignition module.

- The **white and blue wire** should be connected to the **positive side** of the coil, while the **green wire** (with the resistor) goes to the **negative side**. You've got that part right.

- However, don't disregard the green wire just yet. It plays a crucial role in the ignition system.

2. **Ballast Resistor**:

- The green wire you mentioned is likely connected to the **ballast resistor**. This resistor reduces voltage to the coil during normal engine operation (RUN mode). It prevents the coil from overheating.

- When you crank the engine (START mode), the ballast resistor is bypassed, allowing full battery voltage to reach the coil. This ensures a stronger spark during starting.

- If the ballast resistor is faulty or incorrectly connected, it could lead to no spark. Check its condition and connections.

3. **Condenser (Noise Suppression)**:

- The green wire also connects to the **radio-suppression condenser** (if your vehicle had a factory-installed radio). This condenser reduces electrical noise.

- While grounding the wire might work, I recommend replacing the condenser. It's a small investment and can improve ignition performance.

4. **Distributor Points**:

- Inspect the **distributor points** under the distributor cap. Make sure they are opening and closing properly.

- Verify that the distributor shaft is turning when the engine cranks. If it's not, the issue might lie with the distributor itself.

5. **High Tension Wire**:

- Check the **high tension wire** (the one from the coil to the distributor) for any defects or damage.

- Ensure that the wire is securely connected at both ends.

6. **Engine Mileage**:

- If your engine has high mileage, consider checking the distributor shaft for excessive play. A worn-out shaft can affect ignition timing.

Remember, diagnosing ignition issues can be tricky, but methodical troubleshooting usually leads to success. If you've covered these steps and still face problems, consider seeking professional assistance. Best of luck getting that spark back!
