The following steps will prepare the ESX for the cleaning procedure. Make sure the vehicle fuel
gauge reads at least 1/8th of a tank before continuing.
Note: Do not proceed with this setup or any cleaning procedure if the engine oil or coolant
level is low. If necessary add appropriate amount of coolant and/or oil to the engine.
Note: If Intake System Cleaning is desired refer to page 26 for proper instructions.
1. Start the vehicle and allow engine to reach normal operating temperature. Turn vehicle
OFF when the proper temperature is reached.
2. Turn Pressure Control regulator counterclockwise until it is completely open.
3. Connect red (positive) clamp on power cable to red (positive) terminal on vehicle battery.
Connect the black (negative) clamp to a ground on vehicle frame as far from the battery
as possible. All LED’s on keypad should illuminate for one second and buzzer should
pulse. If not, check connections and make sure REVERSE POLARITY LED is not
illuminated. If REVERSE POLARITY LED is illuminated reverse the battery connections.
4. Remove vehicle gas cap to relieve fuel tank pressure.
5. With the engine no longer running, disconnect the vehicle fuel lines from the fuel rail. There
are now four open ends to connect to: the Pressure Line from the fuel tank, the other
Pressure Line going to the rail, the Return Line from the fuel rail, and the other Return
Line to the fuel tank.
6. Connect the proper adapters to the above listed connection points as shown in the
following illustration.
