What should I do if my 1986 Ford truck won’t start?

Ah, the dreaded no-start situation! Don’t worry; we’ll walk through some common troubleshooting steps to help diagnose the issue with your 1986 Bullnose and its 351 Windsor V8. Here’s a systematic approach to get you started:
1. Check the Battery
- Connection: Ensure that the battery terminals are clean and tight. If they’re corroded, clean them with a wire brush.
- Charge: If the battery is weak, jump-start it or use a multimeter to check the voltage. A healthy battery should read around 12.6 volts or higher.
2. Inspect the Starter
- Listen for Clicks: When you turn the key, do you hear a click? If you do, the starter solenoid might be working, but the starter itself could be faulty.
- Tap the Starter: Sometimes, a gentle tap on the starter can help if it’s sticking. It’s an old mechanic’s trick!
3. Fuel System Check
- Fuel Level: First things first—make sure you have fuel in the tank!
- Fuel Pump: If you have fuel, listen for the fuel pump priming when you turn the key to the "on" position. If you don’t hear it, you may need to check the fuel pump or relay.
4. Ignition System
- Spark Plugs: Remove a spark plug and check for wear or fouling. If they look bad, it might be time to replace them.
- Ignition Coil: Check if you’re getting spark by connecting a spark tester to a plug wire and cranking the engine. If there’s no spark, you may need to replace the ignition coil.
5. Check Fuses and Relays
- Inspect the fuse box for any blown fuses related to the ignition system or fuel pump. A quick visual check can save you time.
6. Neutral Safety Switch
- If your truck won’t start in "Park," try shifting to "Neutral" and see if that helps. The neutral safety switch could be faulty.
7. Wiring and Connectors
- Look for any loose or damaged wiring, especially around the starter and ignition. Sometimes a bad connection can create a no-start condition.
8. Check for Error Codes
- If your Bullnose is equipped with an OBD-I system, you can check for trouble codes that might give you a hint about what’s wrong.
If you’ve gone through these steps and the issue persists, it might be worth checking some resources like the Bullnose Garage YouTube channel for specific troubleshooting videos or diving into forums like the Ford Trucks Forum or the Bullnose Ford subreddit for community advice.
Keep your spirits up—troubleshooting can be frustrating, but it’s all part of the journey with classic trucks! If you have any further details about the situation or questions about any of these checks, let me know!

What are effective methods to get rid of rust on my 1986 Ford truck?

Dealing with rust on your Bullnose can be a bit of a chore, but it’s definitely manageable! Here’s a step-by-step guide to help you get rid of rust and keep your classic truck looking sharp:
1. Gather Your Supplies
- Tools: Wire brush, sanding block, sandpaper (various grits), grinder (if needed), and a dust mask.
- Rust Treatment: Rust converter solution or rust remover (like naval jelly).
- Protective Gear: Gloves, safety glasses, and a respirator mask to protect against dust and fumes.
- Primer and Paint: For the final touches, having some rust-inhibiting primer and matching paint will help protect against future rust.
2. Assess the Rust
- Identify the extent of the rust damage. Is it surface rust, or has it penetrated deeper? Surface rust can usually be dealt with more easily, while deeper rust may require more intensive repair.
3. Prepare the Area
- Clean the area around the rust. Remove any dirt, grease, or debris. This will help you see the full extent of the rust and ensure a proper repair.
4. Remove the Rust
- Surface Rust: Use a wire brush or sanding block to remove surface rust. Be gentle to avoid damaging the metal underneath.
- Deeper Rust: If the rust is more severe, use sandpaper or a grinder to remove the rust down to bare metal. Start with a coarser grit (like 80-grit) and work your way to a finer grit (like 120-grit) for a smooth finish.
5. Treat the Area
- Apply a rust converter to any remaining rust spots. This will chemically convert rust into a stable compound and prevent it from spreading. Follow the product instructions for the best results.
6. Clean Again
- After treating the area, clean it again to remove any leftover dust or debris. This prepares the surface for painting.
7. Prime the Area
- Apply a rust-inhibiting primer to the treated area. This will help protect against future rust. Let it dry according to the manufacturer’s instructions.
8. Paint
- Once the primer is dry, apply the matching paint to the area. Depending on the color and type of paint, you may need to apply several coats. Make sure each coat dries completely before applying the next one.
9. Seal and Protect
- Consider applying a clear coat or wax after the paint dries to provide an additional layer of protection against rust.
10. Regular Maintenance
- Keep an eye on your truck for any signs of new rust, especially in areas where moisture can collect. Regular washes and waxing can help protect the paint and metal surfaces.
Bonus Tips:
- For larger rust patches or if you’re not comfortable tackling it yourself, consider consulting a professional body shop.
- Some folks in the Bullnose community have had good luck with products like POR-15 for rust treatment, so it might be worth checking out experiences on the Bullnose Ford subreddit or the Ford Trucks Forum.
Rust repair can be a rewarding project that extends the life of your Bullnose, so roll up your sleeves and get to work! If you have any questions or need clarification on any part of the process, feel free to ask!

How can I identify and fix a coolant leak in my 1986 Ford truck?

A coolant leak can be a sneaky issue, but catching it early is key to preventing more serious problems down the road! Let’s break down the steps to diagnose and fix a coolant leak in your Bullnose:
1. Identify the Source of the Leak
- Visual Inspection: Start by looking for visible signs of coolant. Check around the radiator, hoses, water pump, engine block, and under the truck where puddles may form.
- Dye Test: If you’re having trouble locating the leak, consider adding a UV dye to the coolant. After running the engine for a while, use a UV light to spot the leak.
2. Check Common Culprits
- Hoses: Inspect all coolant hoses for cracks, soft spots, or leaks. These are often the first places to go.
- Radiator: Look for corrosion or damage in the radiator itself. Check the seams and any plastic fittings, as these can deteriorate over time.
- Water Pump: Check the water pump for signs of leaking. Look for coolant around the pump area or a weeping from the weep hole.
- Thermostat Housing: Ensure that the thermostat housing is tight and doesn’t have any cracks.
3. Pressure Test the System
- If you can’t find the leak visually, a pressure test can help. You can rent or buy a pressure tester that fits the radiator cap. By pressurizing the system, you may be able to see where the coolant is escaping.
4. Repair the Leak
- Hose Replacement: If a hose is leaking, replace it with a new one. Make sure to use the right size and type for your Bullnose.
- Radiator Repair: For small leaks, you might be able to use a radiator sealant, but keep in mind this is often a temporary fix. For larger issues, replacing the radiator may be best.
- Water Pump Replacement: If the water pump is the culprit, it’s usually best to replace it entirely. Make sure to replace the gasket as well.
- Thermostat Housing: If this area is leaking, consider replacing the gasket or the entire housing if it’s damaged.
5. Refill and Bleed the Cooling System
- After making repairs, refill the cooling system with the appropriate coolant mixture (50/50 antifreeze and distilled water).
- Be sure to bleed any air from the system, as trapped air can cause overheating. Run the engine with the radiator cap off until the thermostat opens, and watch for air bubbles escaping.
6. Monitor the Situation
- After repairs, keep an eye on the coolant levels and check for any signs of a leak. It might take a little time to ensure the issue is fully resolved.
7. Regular Maintenance
- Check your coolant levels regularly and keep an eye on hoses and connections. Preventive maintenance can save you headaches down the line!
