Fuel Injector: Service and Repair

Fuel Pump Fuse:

REMOVAL

3. Remove the following:
Electrical harness.
Spark plug wires.
Fuel tube securing bolts.
4. Disconnect the fuel delivery and return hoses.
NOTE: Make a note or sketch of the position of injector terminals in relation to where the wiring harness was situated. This will aid in reassembly.

WARNING: Do not place the injector or fuel rail in a vise, this may cause irreparable damage.
6. Using a sharp knife or a single edge razor blade cut through the hose (do not damage the fuel rail when cutting).
7. Remove the injector and hose.
