• Q: How to service and repair fuel injectors on 2000 Toyota MR2 Spyder?

  A: The process of fuel injector service requires removal of the suspension upper brace along with the No.2 cylinder head cover then separation of the PCV hose and three wire harness clamps from their attaching brackets. The first step requires disconnecting the four injector connectors while also removing two bolts which keep the delivery pipe attached to the cylinder head. Then disconnect both the delivery pipe and its four injectors. Pay attention to prevent dropping the injectors throughout this step before uninstalling both spacers and four grommets to extract four injectors from the delivery pipe and unfasten O-rings from each injector. Apply spindle oil or gasoline to new O-rings before placing them onto each injector followed by the two spacer pieces and four new insulators onto the cylinder head. After treating the delivery pipe contact areas with spindle oil or gasoline, carefully push the four injectors downward while turning them clockwise and counterclockwise to install them in the delivery pipes with their connectors facing upward. Secure the delivery pipe equipped with four injectors onto the cylinder head while temporarily tightening both bolts and test for appropriate injector rotation; repeat the O-ring check if the injectors lack smooth movement. The technician should tighten the two bolts to 19 Nm (190 kg.cm, 13 ft.lb). After tightening applies the four injector connectors. The last steps involve reattaching the three wire harness clamps while reinstalling the PCV hose then installing the No.2 cylinder head cover and the suspension upper brace.
