Re: Control board not commanding FAV to open .
 

As I said earlier. I will check the internal of the FAV on Monday. Both. The coil failsafe was the original cause.
Remind me what car and jets you are using.

Audi S5 and a 1.0mm -500cc jet spraying at the TB

Re: Control board not commanding FAV to open .
 

Have you checked the jet for blockage before shipping all those parts back to me? That is the most obvious step to do first. Judging from the condition of the filter of the FAV inlet , worth checking the jet and the in-tank filter for blockage.

Can you send a a picture of the in tank filter? unless it is all new since you changed over to DI tank.

Re: Control board not commanding FAV to open .
 

Yes I did look over the filter and nothing stood out to me as far as it being clogged and yes I have since tossed it when I switched tanks and setup, I also checked the jet during the first stages of trying to figure everything out and when I got the replacement FAV from Howerton the jet was spraying perfect everything was working for a day, I went and redialed in the flow, threshold etc... then parked the car over night and the next day it was back to things not flowing again.

All tests are completed, every part is working fine (including controller. Only the FAV was broken it doesn't look very healthy from outside either.
We need to look at the installation now after you reinstated all the components.

Please update what the actual issue is on your system now that we have ruled out the equipment.

Will do, soon as I have everything put back together! And thank you again!

Re: Control board not commanding FAV to open .
 

So it must've been the FAV/relay... hooked everything back up last night, didnt change any of the cables etc.. and it's working perfectly again. Thank you very much for your help, glad its solved now!

Re: Control board not commanding FAV to open ... not true
 

It will be the FAV coil. It could be damaged by prolong SYS test.
