Mechanical Inspection: Notes
NOTE:
For component locations and connector identification, see COMPONENT LOCATIONS and CONNECTOR IDENTIFICATION in appropriate SELF-DIAGNOSTICS article. After each repair procedure has been completed, reconnect all components.
Check engine mechanical condition with a compression gauge, vacuum gauge or scan tool. See scan tool manual for specific instructions.
WARNING:
DO NOT use ignition switch during compression tests on fuel injected vehicles. Use a remote starter to crank engine. Fuel injectors are triggered by ignition switch during cranking mode, which can create a fire hazard or contaminate the engine's oiling system.
