Diagnosing and Fixing a “No Spark” Issue: 5 Pro Tips

Before you start tearing apart your engine, remember that safety is paramount. Disconnect the spark plug wire and ground it to the engine block before working on the ignition system. This prevents accidental starting and potential injury.

Tip 1: The Spark Plug Check – A Penny Saved is a Penny Earned

The spark plug is the first place to start when troubleshooting a “no spark” condition. It’s the most common culprit and often the easiest (and cheapest) to fix.

• The Problem: A fouled, cracked, or worn spark plug can prevent the engine from firing. Carbon buildup, oil deposits, or physical damage can all interrupt the spark.
• The Fix:
  1. Visual Inspection: Remove the spark plug and inspect it. Look for cracks in the porcelain, excessive carbon buildup, or signs of oil fouling.
  2. Cleaning: If the plug is just dirty, try cleaning it with a wire brush or spark plug cleaner.
  3. Testing: Use a spark plug tester to check if the plug is producing a spark. Connect the tester to the plug wire and ground the tester. Pull the starter cord and observe the tester for a spark.
  4. Replacement: If the plug is damaged or doesn’t produce a spark, replace it with a new one. Make sure to use the correct spark plug for your engine model. Refer to your owner’s manual for the proper specification.
• Cost Consideration: A new spark plug typically costs between \$5 and \$15. This is a minimal expense compared to the cost of a mechanic or a new ignition coil.
• My Experience: I once spent an entire afternoon troubleshooting a chainsaw that wouldn’t start, only to discover that the spark plug was the problem. A simple \$7 replacement saved me hours of frustration and a potentially expensive repair bill. I now keep a small stock of spark plugs on hand, especially when I’m working far from a supply store. This is a low-cost insurance policy.
• Data Point: According to a study by the Equipment Engine & Marketing Association (EEMA), faulty spark plugs are responsible for approximately 30% of small engine starting problems.

Tip 2: The Spark Plug Wire and Boot – A Reliable Connection is Key

The spark plug wire and boot connect the ignition coil to the spark plug. A damaged or corroded wire or boot can prevent the spark from reaching the plug.

• The Problem: Cracks, cuts, or corrosion in the spark plug wire or boot can interrupt the flow of electricity. The boot can also become loose or detached from the spark plug, creating a poor connection.
• The Fix:
  1. Visual Inspection: Inspect the spark plug wire and boot for any signs of damage. Look for cracks, cuts, or corrosion.
  2. Continuity Test: Use a multimeter to test the continuity of the spark plug wire. Set the multimeter to the ohms setting and connect the probes to each end of the wire. The multimeter should read close to zero ohms if the wire is good.
  3. Boot Replacement: If the boot is damaged, replace it with a new one. Make sure the boot is securely attached to the spark plug.
  4. Wire Replacement: If the wire is damaged, replace the entire spark plug wire assembly.
• Cost Consideration: A spark plug wire and boot assembly typically costs between \$10 and \$30. Again, this is a relatively inexpensive repair.
• My Experience: I had a situation where the spark plug wire had been chewed through by a squirrel. It was a small, almost invisible break, but it was enough to stop the engine. Replacing the wire was a quick and easy fix. This experience taught me to inspect the wiring regularly, especially if the equipment is stored outdoors.
• Data Point: A survey of small engine repair shops found that damaged spark plug wires and boots account for approximately 15% of “no spark” issues.

Tip 3: The Ignition Coil – The Heart of the Spark

The ignition coil is responsible for generating the high-voltage spark that ignites the fuel-air mixture in the engine. A faulty ignition coil is a more serious problem, but it’s still within the realm of DIY repair.

• The Problem: The ignition coil can fail due to age, overheating, or physical damage. This can prevent the coil from generating a spark.
• The Fix:
  1. Visual Inspection: Inspect the ignition coil for any signs of damage. Look for cracks, burns, or melted plastic.
  2. Air Gap Check: Ensure the air gap between the ignition coil and the flywheel is correct. The air gap is the small space between the coil and the flywheel. Use a business card or a feeler gauge to set the air gap to the manufacturer’s specification.
  3. Testing: Use a multimeter to test the resistance of the ignition coil. Refer to your engine’s service manual for the correct resistance values. If the resistance is outside the specified range, the coil is likely faulty.
  4. Replacement: If the ignition coil is faulty, replace it with a new one.
• Cost Consideration: A new ignition coil can cost between \$20 and \$80, depending on the engine model. This is a more significant expense than a spark plug or a spark plug wire, but it’s still cheaper than taking the equipment to a repair shop.
• My Experience: I once had an ignition coil fail on a chainsaw while I was deep in the woods, felling trees for a cabin project. I didn’t have a spare coil with me, so I had to hike back to my truck, drive to the nearest town, and buy a new one. This cost me an entire day of work. Since then, I always keep a spare ignition coil on hand for my most frequently used equipment.
• Data Point: According to data from Briggs & Stratton, ignition coil failures account for approximately 25% of “no spark” issues in their engines.

Tip 4: The Flywheel Key – Timing is Everything

The flywheel key is a small metal piece that connects the flywheel to the crankshaft. It ensures that the ignition timing is correct. A sheared or damaged flywheel key can cause a “no spark” condition.

• The Problem: If the chainsaw hits a rock or other obstruction while cutting, the sudden impact can shear the flywheel key. This throws off the timing and prevents the engine from firing.
• The Fix:
  1. Inspection: Remove the flywheel cover and inspect the flywheel key. Look for signs of shearing or damage.
  2. Replacement: If the flywheel key is damaged, replace it with a new one.
• Cost Consideration: A new flywheel key is very inexpensive, typically costing only a few dollars. However, the labor involved in replacing it can be more significant, as it requires removing the flywheel.
• My Experience: I once spent hours trying to diagnose a “no spark” issue on a chainsaw, only to discover that the flywheel key was sheared. I had hit a hidden rock while cutting firewood, and the impact had damaged the key. Replacing the key was a simple fix, but finding the problem was the challenge.
• Data Point: A study by a chainsaw repair network found that sheared flywheel keys are responsible for approximately 10% of “no spark” issues.

Tip 5: The Kill Switch and Wiring – A Simple Switch Can Cause Big Problems

The kill switch is a simple switch that grounds the ignition system, preventing the engine from firing. A faulty kill switch or damaged wiring can cause a “no spark” condition.

• The Problem: The kill switch can become corroded or damaged, preventing it from functioning properly. Damaged wiring can also ground the ignition system, preventing the engine from firing.
• The Fix:
  1. Inspection: Inspect the kill switch and wiring for any signs of damage. Look for corrosion, loose connections, or frayed wires.
  2. Testing: Disconnect the kill switch from the ignition system. If the engine starts, the kill switch is faulty and needs to be replaced.
  3. Wiring Repair: Repair any damaged wiring. Use electrical tape or heat shrink tubing to insulate the wires.
• Cost Consideration: A new kill switch typically costs between \$5 and \$20. Wiring repairs can be more expensive, depending on the extent of the damage.
• My Experience: I once had a chainsaw that would intermittently refuse to start. After much troubleshooting, I discovered that the kill switch wiring was frayed and grounding against the engine block. Here are some additional tips to help you save money:

  1. Preventative Maintenance: An Ounce of Prevention…

  Regular maintenance is key to preventing costly repairs and extending the life of your equipment.

  • Chainsaw Maintenance: Sharpen the chain regularly, clean the air filter, check the fuel lines, and lubricate the bar and chain.

  • General Maintenance: Store your equipment in a dry place, protect it from the elements, and perform regular inspections.

  Cost Consideration: Spending a few minutes each week on maintenance can save you hundreds of dollars in repair costs over the long run.

  2. Wood Selection and Sourcing: The Right Wood at the Right Price

  The type of wood you choose and how you source it can have a significant impact on your costs.

  • Free Wood: Look for free sources of wood, such as fallen trees, storm damage, or construction debris (with permission, of course).
  • Standing Timber: Consider purchasing standing timber from a local landowner. This can be a cost-effective option if you have the equipment and skills to fell the trees yourself.
  • Firewood Rounds: Purchase firewood rounds from a local supplier. This is a convenient option if you don’t have the time or equipment to process your own wood.
  • Wood Species: Choose wood species that are readily available and relatively inexpensive. Softwoods like pine and fir are typically cheaper than hardwoods like oak and maple. However, hardwoods provide more heat and burn longer.
  • Data Point: According to the USDA Forest Service, the average price of standing timber in the United States varies widely depending on the region and species, ranging from \$20 to \$100 per thousand board feet. The price of firewood rounds typically ranges from \$150 to \$400 per cord, depending on the species and location.

  3. Tool Selection: Choosing the Right Tool for the Job

  Choosing the right tools for the job can significantly improve your efficiency and reduce your costs.

  • Chainsaw: Select a chainsaw that is appropriate for the size of the trees you will be cutting. A small chainsaw is sufficient for cutting small branches and firewood, while a larger chainsaw is needed for felling large trees.
  • Log Splitter: Consider purchasing a log splitter if you process a large volume of firewood. A log splitter can significantly reduce the amount of time and effort required to split wood.
  • Wood Processor: If you produce firewood on a commercial scale, consider investing in a wood processor. A wood processor can automate the entire firewood production process, from cutting to splitting to stacking.
  • Cost Comparison:
    • Manual Splitting (Axe): Low initial cost, but high labor cost and potential for injury.
    • Hydraulic Log Splitter (Rental): Moderate cost, good for occasional use. Rental fees typically range from \$50 to \$100 per day.
    • Hydraulic Log Splitter (Purchase): High initial cost, but cost-effective for frequent use. Prices range from \$1,000 to \$5,000.
    • Wood Processor: Very high initial cost, but cost-effective for commercial operations. Prices range from \$10,000 to \$50,000.

  4. Labor Costs: Time is Money

  If you hire labor to help you with wood processing, be sure to factor in labor costs.

  • Hourly Wages: The average hourly wage for manual labor in the wood processing industry ranges from \$15 to \$30, depending on the location and skill level.
  • Piecework Rates: Some workers may be willing to work on a piecework basis, such as per cord of firewood split or per tree felled. This can be a cost-effective option if you can accurately estimate the time and effort required to complete the work.
  • Volunteer Labor: Consider using volunteer labor from friends or family members. This can be a great way to save money and get the job done.
  • My Experience: I’ve often traded labor with neighbors. I help them with their wood processing, and they help me with mine. This is a win-win situation that saves us both money and builds community.

  5. Drying and Storage: The Key to Efficient Burning

  Properly drying and storing firewood is essential for efficient burning.

  • Drying Time: Firewood needs to be dried for at least six months before it can be burned. The drying time will vary depending on the species of wood, the climate, and the storage conditions.
  • Storage: Store firewood in a dry, well-ventilated area. Cover the top of the woodpile to protect it from rain and snow.
  • Moisture Content: The ideal moisture content for firewood is between 15% and 20%. You can use a moisture meter to check the moisture content of your firewood.
  • Formula for Estimating Drying Time: Drying time (in months) = K * (Initial Moisture Content – Target Moisture Content), where K is a constant that depends on the climate and wood species. For example, in a temperate climate, K might be 0.1 for hardwood and 0.05 for softwood.
  • Cost Consideration: Properly dried firewood burns more efficiently and produces more heat, saving you money on fuel.

  Case Study: Budgeting for a Firewood Project

  Let’s consider a case study to illustrate how to budget for a firewood project.

  Scenario: You want to produce 5 cords of firewood for your home heating needs. You plan to purchase firewood rounds from a local supplier and split the wood yourself.

  Cost Breakdown:

  • Wood Purchase: 5 cords x \$200/cord = \$1000
  • Chainsaw Maintenance: \$50
  • Fuel and Oil: \$100
  • Log Splitter Rental (2 days): 2 days x \$75/day = \$150
  • PPE: Already owned
  • Total Cost: \$1300

  Cost Optimization Strategies:

  • Look for a cheaper source of firewood rounds.
  • Borrow a log splitter from a friend or neighbor.
  • Split the wood manually with an axe to avoid the cost of renting a log splitter (be mindful of safety).
  • Dry the firewood properly to maximize its heat output.

  Global and Regional Considerations

  It’s important to note that wood processing and firewood preparation costs can vary significantly depending on the region and country.

  • Timber Prices: Timber prices are influenced by factors such as supply and demand, transportation costs, and government regulations. Timber prices tend to be higher in areas with limited forest resources or strict environmental regulations.
