When I turn the key, the usual visuals show up, but the engine does not turn over. Lots of fresh fuel.

The engine on a Kubota LA434 may not turn over despite having fresh fuel due to several possible causes:

1. Safety Interlocks: If any safety switches (such as seat switch, PTO switch, or clutch switch) are not engaged properly, the engine will not crank.

2. Battery Issues: A weak or dead battery, corroded terminals, or loose connections can prevent the engine from turning over.

3. Starter Motor or Solenoid: A faulty starter motor or solenoid can prevent cranking.

4. Fuses or Relays: Blown fuses or defective relays in the starting circuit can interrupt power to the starter.

5. Wiring or Ignition Switch: Damaged wiring or a faulty ignition switch may block the signal to start the engine.

6. Hydraulic Lock or Load: If hydraulic pressure is not released properly, it may cause resistance that prevents engine cranking.

7. Fuel System Pressure: If fuel lines are under high pressure or partially blocked, it may affect engine function even with fresh fuel.

Each of these should be checked systematically to identify the root cause.
