Tree id and prognosis

Anyone know what this tree in our front lawn is, and how ill is it?  I had to trim a few dead branches off the other week.  It's about 6-8ft tall and has arching down branches.

It might be a crab apple.  Does it fruit?

No fruit.

It's a cherry, probably a Japanese cultivar. The bark damage is probably from bacterial canker, there's often a sort of amber resin at the branch junctions.

Looks like one of the flowering cherry varieties to me as well.

Thanks.  I googled around japanese cherry, and it seems to be:  Prunus serrulata - either Sato-zakura - Japanese village cherry, or,  from wiki:  'Kiku-shidare'. Cheal's Weeping Cherry. Stems weeping; flowers double, pink. Tends to be short-lived.

I don't think it's happy as it's hardly grown in 7yrs.  Perhaps were could feed it somehow? Hopefully treat the canker too.
