you've got to get in there with an ohm meter to see if the pump has electrical continuity~ if it does, measure the connector for the presence of 12 volts~

kink or break in the wire...traverse it's length to find the kink~
Thanks alot found the break in the line. Got the pump running. If you wouldnt mind got another issue the passenger side is to high. What would be the problem there.

check for a restriction in the piping...crimped during repairs?

...the "manifold" as it were is not distributing the pressures correctly...see if you can spot an obstruction...perhaps a bolt that is too long mountin' the thing~
i took the lines off of the block not sure if they are in the right places
