What Causes the Engine Not to Turn Over During Startup?
1 Answers
There are several reasons why the engine does not turn over during startup: 1. Fuel supply system issues: Blockage in the low-pressure fuel line, loose or leaking fuel lines, air in the high-pressure fuel line, poor technical condition of the fuel injectors, incorrect fuel injection timing. 2. Starting system issues: Power supply failure, poor contact in the electromagnetic switch, poor contact between the starter motor commutator and brushes, clutch slippage in the starter transmission mechanism. 3. Insufficient cylinder compression pressure: Leakage due to damaged cylinder gasket, leakage due to improperly sealed valves, leakage due to worn piston and cylinder liners. 4. Insufficient air intake: Clogged air filter element.
