Hyster H 90 FT:
Not starting

Used to run fine. Now just died. The started used to be a wonky, I swapped that out. Now when starting, I can hear gas pump into the engine but still won't turn over. All the fuel filters have been cleaned and has a new fuel pump. What maybe the issue? When enginotion turned off, I can hear fuel back into the tank.

To diagnose your Hyster H 90 FT not starting:

1. Test fuel pressure to ensure it's within specs despite the new pump.
2. Check injectors for proper operation and signal.
3. Confirm the ignition system has a good spark by inspecting spark plugs and coils.
4. Verify airflow and throttle are clear and functioning.
5. Inspect critical sensors (crankshaft and camshaft) and wiring for proper connections.
6. Ensure no safety interlocks are preventing the start, and check the ECU for any stored error codes.
