2000 Cadillac DeVille Fuel Injector Parts and Q&A

• Q: What tools are required to service and repair the fuel injector on 2000 Cadillac DeVille?

  A: Three essential tools necessary for Fuel Injector maintenance and repair are fuel pressure gauge (J 34730-1A) together with Fuel Injector removal tool (J 43013) and fuel line quick-connect separator tool set (J 37088-A). Lowering the fuel pressure should be the first step to perform. First detach the Fuel Rail from the intake manifold followed by taking out the Fuel Injector assembly. The service starts with discarding the Fuel Injector upper o-ring and lower o-ring. Before applying the new o-rings to the Fuel Injector you must lubricate them with clean engine oil. Source the Fuel Injector to the Fuel Rail after which you should reconnect the Fuel Rail assembly. Reinstall the negative cable on the battery before tightening the fuel filler cap. An inspection for fuel leaks should begin by turning on the ignition for 2 seconds followed by keeping it off for 10 seconds before a second check of the fuel leakage. The last step requires installation of the intake manifold sight shield onto the engine and secure it with intake manifold sight shield nuts which must be tightened to 3 n.m (27 lb in) before putting back the rear seat cushion.
