2000 Buick LeSabre Fuel Injector Parts Questions & Experts Answers

• Q: How to remove and install fuel injectors properly on 2000 Buick LeSabre?

  A: The first step to remove fuel injectors requires two procedures: decrease fuel pressure while removing the Fuel Rail component. Start by removing the retaining clips of the fuel injectors before taking out the fuel injectors. Then proceed to remove the upper and lower Fuel Injector o-rings one by one. Replacements of o-rings belong to fuel injectors during servicing must always be performed because they help create proper fuel leakage prevention. The nylon device known as o-ring back up will maintain proper positioning of the lower Fuel Injector O-Ring during Fuel Rail installation and should be put back when complete to avoid vacuum leaks and related driveability problems. The installation requires ordering appropriate fuel injectors that have black upper o-rings combined with brown lower ones despite their identical size yet different material composition. By applying engine oil to all new o-rings you must install the o-ring back up and then put on the lower Fuel Injector O-Ring before adding the upper Fuel Injector O-Ring. The procedure ends by joining the Fuel Injector to the Fuel Rail before using retaining clips to fasten it while reassembling the rail components and installing the Fuel Injector sight shield.
