Fuel Systems: Notes
WARNING:
ALWAYS release fuel pressure before disconnecting any fuel injection-related component. See FUEL SYSTEM PRESSURE RELEASE
. DO NOT allow fuel to contact engine or electrical components.
CAUTION:
Do not insert test equipment probes into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal can cause a poor connection, which can result in system failures. Always use the Connector Test Adapter Kit (J 43907) to frontprobe terminals. Do not use paper clips or other substitutes as they can damage terminals and cause incorrect measurements.
NOTE:
Manufacturer does not provide testing procedures for many individual systems and components. For fuel system testing not listed, perform related DTC testing procedure. See DIAGNOSTIC TROUBLE CODE DEFINITIONS
in SELF-DIAGNOSTICS - 2.2L ION article.
NOTE:
Perform powertrain diagnostic system check prior to testing, and after completing any repairs. See DIAGNOSTIC SYSTEM CHECK - ENGINE CONTROLS
under SELF-DIAGNOSTIC SYSTEM in SELF-DIAGNOSTICS - 2.2L ION article.
