3. Faulty Starter Motor

The starter motor is used to start the engine and without it the engine may start slowly or fail to start at all. Problems with the starter motor can be caused by;

  • Dirty and contaminated fuel pipes and fuel filter.
  • Worn piston rings.
  • Wrong valve timing and hence low compression or worn cylinder bores.

Troubleshooting Faulty Starter Motor

In order to solve problems relating to the starter motor one can try to do the following to try and address the problems;

  • Flushing and cleaning the fuel pipes and changing the fuel filter.

  • Blown head gasket or cracked engine block or cylinder head hence resulting in the coolant mixing with the fuel air mixture in the combustion process.

Troubleshooting White Engine Exhaust Problem

When the engine exhaust becomes white, the following can be done to try and address the problem;

  • Replacing the worn piston rings urgently.
  • Adjusting the timing to ensure proper combustion.
  • Inspecting the entire engine including the head gasket and cylinder head to ensure it has no cracks. If are cracks found they need to closed to prevent coolant from mixing with fuel air mixture.
