Problems with set up

[trmurphy21]

Hi Richard. I'm having a few issues getting my hsf3 system up and running. I've everything installed but the system won't prime. When I put the sys jumper in nothing happens.
Also I turned 4the threshold down when I rev the engine the gauge cuts out and the water level light comes on and nothing from the jet. I have idc on the controller and map signal I've soldered the mps link and b for the flow map table for the single jet.

I've checked and double checked all wiring and piping it's all fine as far as I can see. You have wattsapp I can send you a video? Cheers
