E6GMX Manual

A.3 Starting problems
Fuel Pump doesn't prime when ignition switched on
The Haltech E6GMX will attempt to run the Fuel pump for about 2 seconds just after the
ignition is switched on. The fuel pump relay should be heard clicking in and out with the fuel
pump.
Engine makes no attempt to start
Check the following:
Does the engine run with the Standard ECU
ECU is operating (will communicate ONLINE) during cranking
Battery voltage and connections
Fuel Pump runs
Injector fuse is OK and injectors fire
Ignition system is operating properly and spark is available
Ignition timing is correct
If the engine is flooding, reduce the bars in the fuel map that are being used during cranking
in the fuel map, the coolant correction map and the cold prime map.
If the engine is not receiving enough fuel and increasing those bars does not help, check that
fuel pressure is available and that the injectors operate properly (are cleaned and flow-tested).
A.4 Idling Problems
If the engine will not idle when cold but will when the engine is warm then the coolant
correction map may need to be adjusted.
If the engine idles too fast or too slow, and you are using an Idle Air Control Motor, firstly
check that the Idle Speed Control is enabled, and then lower the target idle setting if
necessary. If not using the idle air control motor then adjust the idle using the idle adjust
screw on the throttle body. Check for any air leaks in the manifold.
Check the ignition timing at idle and adjust if necessary.
If the engine surges or hunts at idle then the mixtures and timing are wrong. Adjust the fuel
maps near idle conditions.
In some circumstances it may be necessary to use the Zero Throttle Map. Consult Chapter 6
[6.2] for information on using the Zero Throttle Map.
A.5 Light throttle and Cruising Problems
If the engine falters under light load then the mixtures may be incorrect, check the Fuel Maps.
