  Q: How to replace the fuel rail assembly on Cadillac XLR?

  A: The replacement of Fuel Rail assembly begins by disconnecting the negative Battery Cable. Beginning with the removal of the Fuel Injector sight shield the technician will follow with fuel pressure relief using ch 48027 or by applicable procedures. Apply gm x 30a spray engine cleaner or an equivalent to clean the Fuel Rail assembly but avoid submerging it in liquid cleaning solvent. The first action detects Fuel Rail, positive crankcase ventilation (PCV) air tube, and each Fuel Injector electrical connectors during the fuel feed and return pipe and pcv air tube removal from the cam cover. Move the engine wiring harness away from the Fuel Rail stud before cutting the retaining clips then place it on the side. Disassemble the Fuel Rail attachment studs before removing the Fuel Rail with a decision to discard the lower o-ring seals contained in the injector assembly. The process of replacing the Fuel Rail requires removal of all the fuel injectors. You need to prepare new lower injector o-ring seals with engine oil before placing them during installation while adding fuel injectors if required. Position new o-ring seals on the tip of each injector spray opening before mounting the Fuel Rail. Secure the Fuel Rail attaching studs at 9 n.m whereas the harness needs installation onto the clips followed by tightening the Fuel Rail stud. Fitting new lower injector o-ring seals with engine oil requires a clean oil application. Install fuel feed and return tubes into the Fuel Rail and connect the Fuel Injector electrical links to each component. Complete the second step by inspecting for leaks after first turning the ignition on with engine off for two seconds then viewing for leaks while keeping the ignition off for ten seconds and re-starting the on position. Reinstall the sight shield after completion of the procedure.
