HFS-3 not spraying ::mystery solved::
Car is Audi S4 2.7BiT and I?ve just installed HFS-3 system and I?m having problems with HFS-3, its not spraying. After install the system was tested by linking up ? INJ? and ?SYS?
on the controller and it was spraying. When I start the car the red "s" and w-injection lights are on in the gauge so it should be ready to spray but under acceleration I don?t see any bars lighting up to show water been sprayed. |

Re: HFS-3 not spraying
A few questions...
1. Does the green led on the controller flicker in time with RPM? 2. Is the fuel injector standard?

2. NO, I?m running EV14 72lbs. (so roughly double over stock). |

Re: HFS-3 not spraying
What is Is the coil resistance of the EV14, 16 ohm or 2.5 ohm. If it is a 2.5ohm injector, you need to use the green harness supplied with the system.

Re: HFS-3 not spraying
Did the spraying test today again but the pump didn?t power up. Fisrt time we installed the system we had wrong wiring diagram for the car but that time it sprayed but had other issues HFS-3 working correctly.
This is how I did the test: 1. I disconnected the 6mm hose from FAV 2. Took the jumper from FAV (it says "inj" in the manual but its "FAV" in the controller) 3. turned on the ignition 4. Put the jumper to the SYS Nothing happened. Does this mean an install error or could I check something else? This is what the contoller looked pefore I Took the jumper from "FAV" |

Re: HFS-3 not spraying
I did spray test as said in the manual:
2. Priming and purging of the system: a. Fill up the tank with water half way. b. Disconnect the 6mm hose from the FAV assembly and put the hose into a container securely. c. Ignition switch in pre-crank position and gauge is switched on. Uncover the controller and pull out the ?Inj? jumper (disabling the FAV) and put it to the link marked ?SYS?. The pump should power up and water should come out of the 6mm hose within a few seconds, Let it run for a 10-20 seconds so that trapped air and debris are purged. Although my problem also is my gauge won?t light up when I turn the ignition on. It only lights up 15s after I?ve started the car. I did send email to Rickhard about this but I think he?s still out of office. |

Re: HFS-3 not spraying
If it lights up 15s after starting the car, then you have a wiring issue. The red wire on the molex connector is the main power supply, BUT the red wire of the gray connector energizes a main relay to let that power flow. So where ever you have the red wire of the gray harness tapped it is not getting power in the pre-crank position to let the system turn on.

Re: HFS-3 not spraying
Can you tell me the serial number of the controller. The wire of the RJ connector seemed to be pulled out.
