I have an engine error code P0410. The air pump does not come on when engine is started. The 60 amp fuse in the engine fuse box was blown. The pump and hoses were filled with water. I replaced the fuse and the check valve on the manifold. I figured this was faulty which caused the water in the hoses and pump. I removed the plug from the pump and checked for 12 volts after the engine was started. No voltage was present. I removed the relay from the pump and disconnected the plug. I measured 12 volts across the coil. Figured the relay was bad and replaced it. Still no 12 volts at the pump connector. Could use any help from here.

I'm guessing the brakes need to be replaced.

thank you

my a/c only works on 4 now and the miles show up in odometor but not sppedometor. ck engine light, airbag light and change oil light always on.
