Just an update,tapped the slide back got the pump out. Some small parts came out and 2 of the springs were broke. Found an engine out of a gen unit with bad generator, pulled the pump , same engine, put it in bleed it ,runs great. Thanks for all the help. I'm sure I'll be back.

Follow up, took the intake ,lines, and bolts out of the pump. The slide was stuck firm. I went through the stop sol. Hole with a small punch and real small hmer. Before i did anything i sprayed some carb cleaner all over the slide. I barely tapped it and it moved. Lifted it right out. It was...

Ok looked again today and the slide at the top of the pump wont move. Removed the intake, sol. , Injector lines , pump bolts and the slide will not move so i cant line up the pin and slot. Not sure how to remove the pump. Any ideas. Thanks again in advance.
