System Inspection

1. Inspect fuel delivery system components. Check for:

- Discharged battery.
- Damaged connectors.
- Damaged insulation.
- Fuse integrity.
- Inertia switch reset.
- Loose, leaking, or damaged fuel or vacuum lines.
- Adverse driveability symptoms such as rough idle, hard to start, miss, surge, hesitation, backfire.
- Leaking fuel injectors.
- Sufficient fuel in tank.

2. Exercise wiring and connectors for solenoids and other electrical components. Check for problems due to looseness, corrosion, or other damage. Perform this check with engine fully warmed up.
3. If a component is suspected as the cause of a malfunction, correct the cause before proceeding to the next step.
4. If all system inspection checks are OK, proceed to pinpoint tests.

WARNING: Fuel system remains under high pressure even when engine is not running. To avoid injury or fire, release pressure from system before disconnecting any fuel line.
