Flow Bars not lighting

[rroth@vitex.com]

My HFS-5 has been installed about a year on a Nissan 300ZXTT and running well. Yesterday, it appears there is now no flow when triggered. System powers up normal with low water light on initially and then blue Sensor and blue W-Injection lights come on.

I use hte IDC to triger the HFS-5 and the blue Boost light will come on but now no Flow Bars light and the unit goes into falesafe mode and Low Water level light comes on.

Any thoughts?

I could not find any trouble shooting in the user manual.

Thanks,
Randy
