article. Remove air valve or dynamic chamber as necessary. Remove delivery pipe with hoses still connected. Remove fuel injectors. If necessary, secure injectors tightly onto delivery pipe using wire.CAUTION: Ensure injectors are securely tied to delivery pipe. If injectors are not properly secured to delivery pipe, fuel may spray from loose connections.
- Connect a jumper wire between terminals F/P and GND of diagnostic connector located near battery. See Fig 1 . Turn ignition on. Ensure no fuel leakage exists at injectors. After one minute, a single drop of fuel is acceptable. If fuel excessive leakage is present, replace faulty injector.
