After replacing the supply pump and/or the ECM:
The ECM's learned values must be initialized. The engine can be initialized through the intelligent tester or by short-circuiting DLC3 terminals.

Press "Next".
Press "Exit".
Start the engine to check if the initialization is complete. If the engine cannot be started, repeat the initialization procedures from the beginning.
Idle the engine for at least 1 minute under the following conditions:
The water temperature is 60°C (140°F) or more.
The fuel temperature is 20°C (68°F) or more.
Note
Do not race the engine immediately after starting the engine. After warming up the engine, racing the engine is acceptable.
