Need a little help with my ABS pump!

Please help,

My abs pump runs but I can't get any pressure from it. I took the ball (accumulator) off and ran it but no brake fluid came out of the hole. I am assuming that I should get brake fluid squirting from the hole where the ball mounts? Could the pressure switch screw up and not let fluid in to the pump chamber? Which way does the pump turn? My books only explain operation and location but no troubleshooting. Thanks for any help in advance, Rob
 
I took the entire unit out and found the pressure switch was stuck in, thought this would fix it but still no pressure. Any ideas? Please, I really need some rear brakes!
 
My advice is to just yank it out and go conventional. There is a 6 page thread about it. I am rounding up parts as we speak to do my 92. Should git-r-done next week...maybe! :D Bye bye Abs crap...hello actual stopping power!!!!!
