CRANKSHAFT POSITION (CKP) SENSOR

Note. Engine front cover design precisely locates CKP sensor. No CKP sensor adjustment is necessary.

FUEL SYSTEM PRESSURE RELEASE

1. Remove fuel tank cap. Using Fuel Pressure Gauge (T80L-9974-B), release pressure from system at pressure relief valve (Schrader valve), located on fuel injection manifold rail.
2. If fuel pressure gauge is not available, disconnect Inertia Fuel Shutoff (IFS) switch. See INERTIA FUEL SHUTOFF (IFS) SWITCH LOCATION table. Remove fuel cap to release fuel tank pressure. Crank engine for 15 seconds to release system pressure.

Spring Lock Coupling

1. Release fuel pressure. See «FUEL SYSTEM PRESSURE RELEASE»(ref-24211-S32294543282001010400000). Place indicated spring lock coupler over coupling. See «SPRING LOCK COUPLER IDENTIFICATION»(ref-24211-S00515699052001010400000) table. To release female fitting from garter spring, push coupler along tube into coupling. (Scheme 24)
2. Pull spring lock coupling apart. Remove coupler from disconnected spring lock coupling. Check for damaged garter spring and "O" rings. Wipe end of lines with clean cloth.
3. To install, place NEW "O" rings onto tube. Lubricate ends of lines with clean refrigerant oil. Locate White indicator ring (if equipped), which may have slipped down length of tube. Insert White indicator ring into cage of male fitting.
4. Push fitting together with a slight twisting motion. White indicator ring will pop free of cage to indicate that male fitting is properly seated over flared end of female fitting.
