Yes! Hard starting is a common symptom of bad spark plugs.

🔍 Signs Your Hilux Wont Start Due to Spark Plug Issues:
❌ Engine cranks but doesn’t start.
❌ Starts but immediately stalls.
❌ Takes longer to start in cold weather.

📌 Solution: If your Hilux is struggling to start, check:
✔️ Battery health.
✔️ Fuel system pump & injectors.
✔️ Spark plugs & ignition coils.

Replacing old spark plugs can solve hard starting issues in petrol models.
