Well looks like I got the issue sorted out. Replaced the relay and also cut back the meth lines going into the FAV in the engine bay by 1/4" and reinserted, just in case they were somewhat leaking and causing a pressure drop. Pump only turns on when required now...

HFS-3 died
Dear Richard,
I bought an HFS-3 system from Jeff Howerton in 2011 (S/N 10444) for my heavily modified 2007 STI. It didn't worked for a while as the cable that goes to the ECU was crimped incorrectly (The wire that goes to injector 1 on the ECU was the wrong color). After troubleshooting that and wiring the correct cable, it worked perfectly for a long time. I don't drive my car often though. When I'm not using it, I usually fire it up once a month, let it get to operating temp, Check several things, among them that the HFS-3 is working then switch the car off and cover it again. A month ago the HFS didn't turned on. Nothing happened in it. I thought it might be a minor problem and decided to check it afterwards. I did it this month. I checked fuses and connectors, measured voltage on proper pins, connection to ground, and swapped the gauge cable for a CAT6 cable to see if the cable was ok, but nothing happened. I also checked for voltage in all pins on the cable going to the gauge and none has voltage. I checked on the controller but nothing happens if the gauge is not working, so I have no clue what the problem could be. I'm out of basic troubleshooting ideas, and would love any suggestion to what might be happening. I barely use the system as I have different maps on my Accesstuner, and just use the high boost with the aquamist map when I'm up to no good (which is not very often). I will appreciate any help to troubleshoot and fix it. Again, it worked one month, and the next didn't, without even driving the car. Thanks in advance for your attention and help. GS |

Is anyone from Aquamist still monitoring this? Their forum is not working, there is no email address to ask about service... I'm in the dark here.
