It's clear from Avengers, why he wouldn't trust Fury. In fact I wouldn't doubt Tony holding a grudge against Fury for Coulson's death. The last interaction between Fury and Tony, is him with his back turned walking off the bridge. If he would want anyone's help it would be Steve's, but I'm sure there will be a reason for why he can't.
