Troubleshooting for Starting Diesel Generator /Engine 1. Fault Phenomenon The crankshaft rotation speed is normal when starting, but it takes a long time to start, or there are obvious signs that the crankshaft can't start. 2. Failure Cause Air leakage in intake system; low fuel pressure; clogging of air filter; fault of water temperature sensor; malfunction of air Flowmeter; failure of idle speed control valve or additional air valve; failure of cold start injector; leak of injector; Incorrect ignition timing; starting switch to computer connection broken; cylinder compression pressure is too low. 3. Fault Diagnosis and Troubleshooting A. Perform fault self-diagnosis. If there is a fault code, by the fault code to find the corresponding cause of failure. B. Check the vacuum of the inlet during idling. If the vacuum degree is less than 667 kPa, the air leakage in the intake system should be checked at the joints, gaskets, vacuum hoses, exhaust gas reci...
