Make sure the fuel remains enough (0.3 US gal
(1.0 ℓ) minimum) in the fuel tank and add fuel if
necessary before increasing fuel pressure.
1. Connect the fuel pump connector (1).
2. Disconnect the DLC/fuel pump sub harness
connector (2).
3. Before connecting the battery harness cables to
a 12V battery (3), make sure that the battery
harness selector switches (4) are OFF.
