Check the yellow wire that runs from the sensor to the connector at the rad support. It then runs to the relay on the pump. The sensor provides a ground to activate the relay. By grounding it, the pump should run. Not only does it activate the pump relay, it also lights up that dash light. Mine was broken inside the connector at the rad support. I jumped around it with a couple of wire taps.

The yellow connectors are airbag connectors. Don't mess with those.

There's a black connector near the rad support, by the air box, that has the wires from the ride height sensor. One of them is yellow. I'm pretty sure you'll find that is your problem. You should see a ground on that wire when the system calls for the pump to turn on. The pump isn't seeing it. Could be at that connector or anywhere in between.
