Is your rollover sensor broken fallen off or stuck upsidedown? That can cause similar problems. And check all connections. Fuses. Im not sure witch relay is the pump but you can try switching them around and seeing if it turns the pump on.
If you look where your front fenders mount to its like \___/ and in the middle theres a bracket that comes off and the rollover sensor is hanging on that. If you shake it you can hear it swaying around. if u dont it might be stuck.
