  Q: How to service and repair the fuel injector on Chevrolet Tracker?

  A:

  Proceeding with the service or repair of a Fuel Injector requires a step where users should first release the fuel pressure. The first step requires removal of the Throttle Body followed by disconnecting the electrical connector that powers the Fuel Injector. Move on to the hold down bracket at the rear of the Intake Manifold for removal while following it with the bracket bolts extracted from the Intake Manifold before bracket removal. Start by detaching the high pressure and return hoses from the fuel pipes then removing the fuel pipes hold down bracket bolt. First disconnect the 3 retaining bolts attaching the Fuel Rail. Following that, pull out the Fuel Rail and the fuel injectors. Pre-installation tasks require motor oil coating on the fuel injectors o-rings which should then be positioned onto the Fuel Rail before securing the Fuel Rail onto the Intake Manifold while tightening the 3 retaining bolts to 30 n.m (22 lb ft). As the next step install the fuel pipes hold down bolt then secure it to 25 n.m (19 lb ft). Afterward install the Intake Manifold reinforcement bracket and tighten both retaining bolts to 25 n.m (19 lb ft). After installing electrical connectors to fuel injectors you should apply the code reader and activate the fuel pump through the ignition before checking for leaks. Any necessary repairs must also be completed.

  Q: How to replace a fuel injector on Chevrolet Tracker?

  A:

  The first step to replace a Fuel Injector requires you to relieve fuel pressure. Unplug the Fuel Injector electrical connector prior to extracting its mounting bracket at the Intake Manifold rear position along with bolts from the Intake Manifold bracket. The high pressure and return hoses should be pulled from the fuel pipes before the fuel pipes hold down bracket bolt can be removed. Proceed by taking out the Fuel Rail after removing its three retaining bolts and extracting the fuel injectors . Before fuel injectors mount on the Fuel Rail users should apply a thin coat of motor oil to the o-rings and properly fit the fuel injectors onto the rail. The Fuel Rail installation requires a correct fitting to the Intake Manifold where the three retaining bolts must be tightened to 30 n.m (22 lb ft). The procedure requires installation of the fuel pipes hold down bolt followed by bolt tightening to 25 n.m (19 lb ft), after which the Intake Manifold reinforcement bracket receives installation alongside its two retaining bolts that must be tightened to 25 n.m (19 lb ft). Plug in the electrical connectors to the fuel injectors and put on the scan tool. Click on the ignition switch but leave the engine off then use the scan tool to activate the fuel pump followed by leak inspection and repair procedures.
