System Inspection
1. Visually inspect the components of the fuel delivery system.
2. Exercise the wiring and connectors for the solenoids and other electrical components for obvious problems due to looseness, corrosion, or other damage.
3. If a component is suspected as the obvious cause of a malfunction, correct the cause before proceeding to the next step.
4. If all system inspection checks are OK, proceed to the pinpoint tests.
