In the end you need to remove the pump. The pump sitting there thry to pump air will not it any good at all. If it trys to lock up it might cause a problem with the esentric on the front of the cam. To do the test and see if thats the problem just bypass it for now.

It's better to push the fuel through the filter with the pump then try to suck it through. electric pumps are made to push not pull.

Rick lake has some good tips and things to look at as well. It only takes one little piece of crap to give you major headaches.
