ST 205 Intercooler problems Options

I have been a member for a while. There is a lot of usefull info here and I enjoy reading everyones ideas amd suggestions.

I have a problem with my ST205
I have been looking online for a while now. I found some ideas for a fix here but with no sucsess. I have found lots of info on Intercooler(IC) problems.
I'll lay out the problem

My relay mounted off the rad is buzzing and sending my car in to limp mode.
I have checked the ic sensor on the top of the ic. It works fine. I bridged the sensor. The relay still buzzes. I have checked the pump and it works fine. I replace the wire from the ecu (int) intercooler pin from the ecu all the way to the relay.
If I ground out that wire the pump will stay on

I have a feeling its a short in the system. I just can't track it down.


There is a lot of info on the net but none of it seems to have this same problem.
There are a few ways to bypass the system but i would rather fix it not bypass. I found a bypass link here

Any help will be great
Thankyou

Any chance you could take a picture and circle what's buzzing?

What code are you getting btw?

Its a code 54


I have check any/every thing i can think of to fix this. I am slowly running out of ideas and online resourses.
If there is a way to fix it without bypassing I'm at a loss.

I have checked the wire from the Intercooler pin from the ecu harness and replaced it from there back to the realy to make sure of a good conection
