"Well I have run a few good hot cycles through the system. I checked the #13 fuse which was fine, and wired the pump to come on with the key. Turned key on and nothing, so it is definitely the pump. It is just a crazy coincidence that the pump goes out during the install of seperation tubes. Maybe some coolant leaked onto it and shorted it out. Now I have to wait on a pump to arrive to get my S/C back on track. It kicks on just long enough to heat up and kicks off.

we usually put 30-40 miles on the cars before closing the isolation valves (one good heat cycle will do it). with the issue your having now you might as well open them both back up for the time being as you may get a little flow that way. check power to the pump, if good power and no start then ya know what to replace.

you never touched the IC pump durring the installation of the isolation kit correct? and you did fill the overlfow talk back up after install i assume so the pump shouldnt have been affected by the install.

let me knwo what you find and ill help where i can
