Throttle Body Injection (TBI) Setup
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 throttle body, the Return Line from the throttle body, 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.
