Welcome, I'm Chris (aka Moose) I'm an independent contractor here at Just Answer.
Can you access the pump connector, unplug it, monitor across the 2 pins for power and ground, command it on to see if you get the signal to the pump. If your getting signal but no pump operation then its the pump bad, if the pump runs but no fluid comes out then the lines are likely clogged. If you do not get signal, let me know.
Thanks for asking your question and letting me try to help you.

Your rating is my feedback. If I don't get feedback from customers, I will not be able to continue helping customers here.
Rating me good, bad, or not rating at all does not effect the fee you have paid nor does it close the post.
