okay guys
i have done some investigating on DEM
Disconnected pump and connected 12 v pump ran maybe seemed bit noisy but maybe normal
checked fuse to DEM -fuse was blown
replaced fuse started car but not driven fuse still intact this is with pump still disconnected , which this may mean the pump blew fuse ,but pump is running on 12 v
removed DEM and looks clean no water ingress and all terminal look clean no sign of anything blown
so do i connect pump with new fuse intact and risk possible damage to DEM and see if fault goes
thanks heaps for any info
