3 Reason Why Your Car’s Engine Won’t Start | Carson Cars
What’s worse than rushing around to get out the door to make it work on time? How about the engine on your car no turning over? There are numerous thing that can go wrong with the myriad of components that combine to make a car’s engine operate. Understanding the basic operation of the engine, you will discover there are three primary problems that can keep your car’s engine from running. The Everett Engine Repair Experts at Carson Cars explain the fundamental issues:
Bad Fuel Mix
According to automotive experts, up to 85% of gasoline sold at fuel stations in the United States contains less than 10% of the recommended amount of deposit control additives! With odds like that, chances are, your vehicle is operating with a bad fuel mix. Also, it is not uncommon for the stated octane levels to be incorrect (intentional deception!)
So, what happens with repeated, continual use of bad fuel? The Mukilteo Engine Repair Specialists at Carson Cars point out that over time the fuel injectors can clog, causing:
- inadequate fuel supply, causing disruption in combustion
- spray patterns disrupted, which interferes with fuel atomization
Combustion within your vehicle’s engine requires that the fuel/air combination be sufficiently compressed. The primary reasons for decreased or lack of compression are:
- Worn piston rings – allowing the fuel/air mixture to leak around the piston during compression
- Worn valve seals – allowing the fuel/air mixture to leak around the piston during compression
- Faulty cylinder seal – causing leaks
One common cylinder failure occurs between the cylinder head (top of cylinder that holds the valves and spark plugs) and the cylinder body. Usually, the cylinder head is bolted to the cylinder, with a thin gasket sandwiched between the pieces. The gasket provides a good seal between the cylinder and the cylinder head. Small holes can develop between the cylinder and the head if the gasket deteriorates, which causes leaking.
The fuel/air mixture in your car’s engine is ignited by the spark produced from the spark plugs. If one or more plug or wire are fouled, you may notice also notice an increase in fuel consumption in addition to the misfiring of the spark.
Spark plugs can be fouled from deposits of oil or fuel. If the valve seals or guides are worn, or the cylinder seal is bad, oil can be leaked into the combustion chamber. Should you notice a heavy layer of black deposits on the intake valve or the spark plugs, this could indicate leaking oil.
If your car’s engine runs, but misfires, it could be due to:
- one or more fouled spark plug(s)
- one or more worn spark plug(s)
- one or more fouled spark plug wire(s)
- one or more worn/disconnected spark plug wire(s)
