Post-Service Procedures

After the service is complete and the fuel charging system is installed to engine, perform the following steps:
1. Install fuel tank filler cap on fuel tank.
2. Connect battery ground cable.

NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the Powertrain Control Module (PCM) relearns its adaptive strategy. The vehicle may need to be driven 10 miles or more to relearn the strategy.

3. Install Fuel Pressure Gauge T80L-9974-B.

WARNING: The fuel system is normally pressurized to 276 kPa (40 psi). Use care when servicing the fuel system or personal injury may occur.

4. Turn ignition switch ON/OFF several times without starting engine to pressurize the fuel system.

NOTE: Make sure the fuel system maintains pressure. If a loss of pressure is noted, the fuel injector O-rings may be damaged or incorrectly installed, allowing excess fuel to leak into the cylinders. In this case, disassemble the system and repair the problem before starting the engine.

5. Add engine coolant if required.
6. Turn ignition switch ON/OFF several times without starting engine to pressurize system. Check for fuel leaks.
7. Start engine and warm to operating temperature. Check for coolant leak if coolant was removed.

NOTE: Check all connections at fuel injection supply manifold and push connect fittings.

8. Perform Powertrain Control Module On-Board Diagnostics. Refer to Computers and Control Systems / Testing and Inspection.
