I have a 3-year old nectarine tree that is now starting to ooze sap. Does that mean that it is starting to die? Can anything be done? We live in a redwood forest and the tree receives somewhat limited sun. It fruited really well the first year. Last year we got no fruit. The trunk is about 4 inches. I appreciate you taking the time to help.

It sounds like you could have a peach borer problem. This article will help determine if this is indeed the problem and how to fix it: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-borer.htm Another possibility may be peach canker (which can affect any stone fruit tree). This needs to be addressed, but should not need any chemicals to treat it.
