Turn the ignition switch ON and check that the fuel pump operates for few seconds.
If the fuel pump motor does not make operating sound, inspect the fuel pump circuit connections or inspect

If the fuel pump relay, tip-over sensor and fuel pump circuit connections are OK, the fuel pump may be
faulty, replace the fuel pump with a new one.
