Bought a 98 xlt 6 months ago. The bags never leaked off until two weeks ago. I also never heard the pump come on and the ck suspension light was on. I took the really off the core support and tryed another one with no luck. I can get the pump to run by jumping the wires at the realy plug. But the rear doesn't raise. I also tryed running a ground from the battery to the signal ground on the plug and got nothing. Any help would be appreciated.
