It seems to be the same problem of me

i found another source for 12v to power the system .. so the gauge lighting issue resolved .. now once i turn the car off , gauge turn off too !!!! but pump still not working ..


the aquamist came with ground kit , for pump ground wire !!! is it necessary to use i??? because i did not use it .. i just wired the black wire to chassie .. so is it possible that this is the reason why pump not working ??

This is good, do you have a pinout for it? May be you got it from the fuse box?

I wonder if it is the relay?

If you use "SYS" to turn on the pump relay (with "FAV" unpluged). Let me know if you can measure a 12V across the pump. If the ground is bad, you will not see a 12V across the pump connector.

Everything fine , tested the sray by useing the SYS in the controller , than i tested the system by active the F-IDC and everythings perfect ..

richard when i tested the system by SYS it showed me 3bars in the gauge , after that i went to road real test and it showed me in the gauge 4bars only ... so is that mean that system is spraying full flow that i need ?? more info will be usefull .. thanks

Now is a good time to set the gauge to display 5-6 bars at WOT and high RPM. (using the "SC" trimmer on the gauge).
