- Deactivate fuel injection system by removing Digital Motor Electronics (DME) master relay and fuel pump relay before performing compression test. See «DME & FUEL PUMP RELAY LOCATION»(ref-10047-S06975059242000110700000) table. Ensure battery is fully charged.
- Ensure engine coolant temperature does not exceed 95°F (35°C). Turn fasteners ( 2 ) on electric lead cover 90 degrees and remove electric lead cover. Disconnect spark plug connectors.
- Using 16-mm Socket (12-1-171) and Torque Limiter (12-1-172), remove spark plugs. Use Pressure Gauge (11-0-162), Test Adapter (11-0-166) and Tube Extension (11-0-167) to check compression pressure. See «COMPRESSION SPECIFICATIONS»(ref-10047-S03875525742000110700000) table.
