Injector synchronization is setting of all injector racks to a reference position so each injector gives the same amount of fuel to each cylinder. This is done by setting each injector to the same position while control linkage is in a fixed position (called the synchronizing position). Control linkage is at synchronizing position when cylinder No. 1 injector is at fuel shutoff. Since injector No. 1 is reference point for other injectors, no synchronizing adjustment is made to injector No. 1.
Always synchronize an injector when it has been removed and reinstalled.
1. Turn off engine and shut off engine's electrical system. Remove fuel shutoff solenoid to allow injector rack control linkage to move freely during injector synchronization. Remove fuel shutoff solenoid using Spanner Wrench (4C4734). See Fig. 2.
2. Remove valve cover from intake manifold. Remove 4 bolts and cylinder No. 1 rocker arm assembly. See Fig. 3.

3. Apply a small amount of clean engine oil to top of injector. Install Injector Spring Compressor (1U6675) to cylinder head and injector. See Fig. 4. Tighten bolt on Spring Compressor (1V6675) which is threaded into cylinder head hole for rocker arm assembly. This compresses injector. Tap lightly with a soft hammer on spring compressor directly above injector to ensure free movement of injector rack bar.
