Fuel Injectors

To check fuel injectors and circuits, use scan tool. See appropriate injector diagnostic test(s). See DIAGNOSTIC TROUBLE CODE DEFINITIONS in SELF-DIAGNOSTICS - RAM VAN article. To check injector only, disconnect electrical connector. Using a set of fused jumper wires, momentarily apply 12 volts across injector terminals. Injector should click. Remove jumper wires. Using an ohmmeter, check resistance between injector terminals. Resistance should be 10-16 ohms. If injector does not operate as specified, replace injector.
