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~

Yup, sounds like a wire got broken during the repairs. Just like The Judge said. HTH. -Jim

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~

There should be a height sensor under there. Check for a restricted line to the driver's side, as The Judge said. Sounds like the height sensor is on that side as well. This sensor "reads" vehicle trim height and adds or removes air accordingly to maintain proper vehicle standing height. HTH. -Jim
