First time start, no power or anything

[RattyMcClelland]

I bought my hfs3 system early last year but I took my supercharger off so I left the aquamist system uninstalled.

I finally installed it over the last week.

Everything has been wired in except for the ecu cable to the injectors.

The control unit power comes from my stereo switched 12v and is grounded on the own stereo ground. My stereo uses its own power direct from the battery as its a full on high end ice install.

So every thing is connected. But not connected to the fuel injectors.

I thought the system would at least start up and blink without the ecu connected Or does that make a difference?

At the moment absolutely nothing happens, no light or blinks from anything to do with the hfs3 system. Nothing from the gauge.

Annoyingly the car is off to get a full engine rebuild and supercharger fitted so I cannot do much from here on bit instruct my very competant mechanic at performance autoworks. It's getting mapped there too on water meth.

Just read on here that the grey ecu wires need connecting also to power everything up so that such should solve the problem.

Yes. The system needs the fuel injector signals to function.
