Troubleshooting
Green POWER light does not come on
•
Check fuse. A blown fuse may indicate reversed electrical connections or wiring short circuit.
•
Check for power on red wire at the controller and for ground continuity on black wire. Repair broken
wires or bad connections as necessary.
Green POWER light flashes slowly (once per second)
•
101005-101050 models: Sensor input signal is disconnected or under 0.10 volts. Correct sensor wiring.
•
101000 models: Engine not yet running or no duty cycle input. Correct injector tap wiring.
Green POWER light flashes quickly (five times per second)
•
No draw on pump wire detected, correct pump wiring and check for broken wires or poor pump
ground.
•
Pump circuit overloaded. Check for short circuit to ground on blue pump wire.
Green POWER light does not go off
•
Power source is not a switched ignition feed. Relocate red wire to switched feed.
Blue ACTIVE light is on with engine off
•
Wrong MAP sensor-controller combination. Refer to chart (right) to
determine which sensor you have. Try setting the START knob higher.
•
Wrong wire tapped for MAP sensor. Use volt meter to verify correct wire
is being used.
•
Pump ground wire connected to 12V instead of ground. Refer to
installation instructions and wiring diagrams.
Blue ACTIVE light does not come on above set point
•
Lower start knob to minimum, and re-test. May be due to incorrect map
sensor range or poor ground on black wire in the sensor tap wiring
harness.
ACTIVE light is illuminated Red
•
A current overload will illuminate a red indicator light rather than the blue light. This means that
either the current draw by the pump exceeds specifications or that the controller has become
internally overheated. This is generally due to a short circuit in the pumps blue feed wire, or a
defective pump.
If at any time the controller activates the pump when it is not expected stop engine and remove fuse or
turn off switch as quickly as possible.
To avoid hydro-lock, remove all the engines spark plugs and turn
engine over to remove any built up water from the cylinders. If nozzle is mounted in another location than
the intake manifold, take similar measures to ensure excess water is removed from the systems charge
pipes or similar.
If the above troubleshooting fails to resolve the issue, it may be due to a failed control module or another
problem.
