WMI pump not activating

[Careen88]

Hey guys! I just installed a BMS WMI kit, and when I go to purge, I can hear a click but the pump doesn’t kick in! I tested the pump separately and it does work, I was wondering if you guys had any ideas? The FSB is blinking red when I try to do the purge, I have a feeling it shouldn’t?

My first FSB also blinking red and didnt work. I got a new one and then all worked

Any idea what was wrong with the FSB? I’ve checked everything on mine, it’s even blinking red, checked pump with alternate power and that works, jb4 is hooked up correctly…. I’m at a loss

Should be green light I think. I got it replaced by Terry at Burger.

I'm just super confused, because Terry is telling me that it's supposed to flash red?

Ok, I can be wrong, maybe mine didnt light at all. Sorry if so. If all other things is right, maybe you need to test another one.
You are sure settings is right?

Make sure you have map7 set, it doesn't purge unless you have map7 set.

this is partially correct, it will also purge if you have the bit selected that allows for WMI with external inputs such as ecu tunes from other companies.

Hey guys! All good, it was just a bad ground in the end, I’ve got it up and running! I took the car for a test drive, and on the 4th or 5th attempt, the car threw an engine light and lost all power, which I’m thinking may have been over boost? I’m on 91+wmi, and it was about -2 degrees C outside! I shut the car off and the light went away and it’s been driving fine since! Would the EWG wires fix this issue? I should note I’ve got intakes and exhaust, was in comfort mode by accident and want logging at the time so only assuming!

You'd need a JB4 log for tuning advice. If you get a code in dash be sure to read it.
