Intercooler pump not turning on after Afco HX install
Just finished installing Afco Dual Fan Hx, filled it through the top as much as i can with burping. i then turned the car on and the pump never turned on after the car warmed up but it did around 15 minutes in and kept going on and off for a bit then stopped, now it does not start at all, i emptied out the system and tried again cause i thought maybe it had too much air and then tried again with no success yet again. is it possible that i burnt it out? because it almost always had fluid going through it but it was making a fuzzy noise. No CEL, no blown fuse, unplugged the relay and tried manually switching it on without any success, checked the pump plug and i have tried everything that every IC pump thread on the forum suggested and since it did turn on briefly i doubt i messed up the wiring job to do with the Afco fans.
please help |

and FYI if you're asking how i wired up the fans, i cut one of the white wires, specifically the one that is alone not the one next to the black wire, so please tell me if this is correct?
the Afco instructions were not clear at all about which one to cut. so i just copied their picture and i am not sure if i did the correct thing, keep in mind that it did turn on but just briefly. |

Could be low on fluid or air in the system. I'd check that before diagnosing any circuits.

Alright, but shouldn't it turn on? For at least a few seconds because it didn't at all, I filled water directly from the lower port on the supercharger, so the pump has water directly on top of it.

Well, if your pump was dry you've answered your own question...as it is the lowest part of the system it should never be dry. Yes, the pump is probably fried.
Only a 50/50 mix of Dexcool and distilled water should be installed in the system. |

Yes it should shut off if there is air in the system and no fluid is in the pump. |

At this point you have already wired the AFCO fans into the pump so I would just unplug the pump and put 12 volts to it to test. |

The pump circuit should be separate and isolated and is the trigger for the fans. if the fans are running you should see a constant high flow rate in the reservoir. I had the rotofab black tank.
I had ground issues with the relays with mine. I had to add a dedicated ground to the relays but this was a fan issue no a pump one. The pump always ran the fans were intermittent. I am thinking pump issue, but you should be checking the voltage on the IC fuse in the engine bay and see if that is odd. |

Also I'm guessing you have the Afco hx with the fans? If so which power wire did you cut from the pump plug? As I feel like that might be causing an issue and I did it incorrectly, I cut the wire that is on its own not next to the ground black wire. Thanks for your input!

I didn't cut in to the harness but went directly to the IC pump fuse NO3 and tapped off that as a trigger. That brings 12volts to the relays for the fans and keeps the actual pump isolated.

My fans are running all the time now, but my pump is not so I'm guessing the pump is fried or I tapped in the wrong wire? |

The fans on the Afco are designed to operate all the time unless you install a switch.
