Default Re: Datsun 1600 HFS3-Help needed

Now I can see the problem.

It appears after 5 seconds, the (+) of the fuel injector drops out hence the HFS-3 turns off. Reason being the system will not spray accidentally if there is not (+) supply to the fuel inejctors.

If there is a switch between the +12V to the fuel injectors (+), the system will work properly without the 5-second timing turning the system off. Is it possible for you to disable this timer?
