How to fix an MTU 16V4000Gx4 Engine that won't turn over?
- J
  Jeremy PriceAug 20, 2025
  If your MTU Engine doesn't turn over when you try to start it, here are a few things to check: * Make sure the battery isn't low or faulty by charging or replacing it. * Check the cable connections to make sure they are secure. * For electric starters, verify the engine cabling or starter isn't faulty and that cable connections are properly secured. If issues persist, contact Service. * For compressed air starters, check the starting valve or starter cabling and ensure connections are secure. If problems continue, contact Service. * Inspect the engine wiring. Also, check the engine/generator control assemblies and connectors for looseness, and the engine governor plug-in connections. If the running gear is blocked, contact Service.
