I am recently switching my 91 gtu over to a full t2 swap with haltech, and im having trouble.

i recently switched over the fuel pump, and when i am cranking, i dont see a cas signal, and the fuel pump doesn't primer.

whats the proper way to check to see if the fuel pump is operational(since i got one that was used(walbro)) so that i know my fuel pump isnt the problem.

im asking this since i dont have the check connector any more since i swapped.should i just jumper the power wire or???
