System Inspection

1. Visually inspect fuel system components for:
^ Loose, leaking, or damaged fuel or vacuum lines
^ Leaking fuel injectors
^ Adverse driveability symptoms such as rough idle, hard to start, misses, surges, hesitates, backfires
^ Insufficient fuel in tank
^ Discharged battery
^ Damaged connectors
^ Damaged insulation
^ Damaged fuel system components
^ Fuse integrity
^ Tripped inertia fuel shutoff switch

2. Exercise wiring and connectors for solenoids and other electrical components. Check 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 checks are okay, proceed to Pinpoint Tests.
