This could be a pump issue but we need to rule out a restriction in the line first. When you say you disconnected it and had no issue with flow, was that on the line running to the rear window? Where did you disconnect it? If it was from where you used this splicer to repair the line then that would indicate that is the issue. In other words, if you have good flow prior to this but nothing or very little coming out past that, then we need to use something different to repair this line.
I would suggest using a washer line repair kit. They are readily available on Amazon. The main reason is, you used a line that is 3/16 and these lines are normally 11/16. So I think you are causing to much of a restriction in the line.
Let's try and change that out for a larger splice and see what happens.
