How old is this system? It appear the gauge is v10 or v11.

Can you unplug blue harness and tell me if the failsafe light still on?

[chris-mr2]

Not sure what version it is, ive had it a fair while now on another car, ive got a blue circuit board that says HFS3-PWM

Taking out the blue harness appears to make no difference to w-level light being illuminated

HFS3-V1K ISS1 L2 printed on back of board

When you first post said you just installed the HFS3, I though it will be the lastest v3. Hence I was confused with your description. I should have asked you first before diagnosing the problem.

OK, lets start again.

Is this a brand new system out of a box?

[chris-mr2]

It was, I took it of my old car and was in storage for a while, ive bought new harnesses, jets, water lines, filters and fav before the instal on my current car

V1 has a blue circuit board.

I think it would be easier you can make a trip to us (East Sussex) I will be able to test out the controller for you. It is not easy to pin point a problem if the system has been in service for a while and re-installed into another car.

Ok that would work fine for me, when is best for you?
