Definitely in need of repotting then
I don't know whether you can buy specialist citrus compost these days...........if you can, then get it. If not, I use a mix of multi purpose and JI no. 3 but my trees are around 25 to 30 years old. I do use a Citrus feed tho.
I'd suggest you prune back any dead stuff, repot and give a gentle watering until you see new shoots appearing. Misting the tree can help too (but bear in mind the weather - you don't want to make it soggy ). Rain water is preferable.
Once it's started into growth, you should be ok. One word of warning tho........if you keep in a g/h or conservatory all year round, red spider mite can be a problem so much better if it can live outside for most of the year.
Best of luck..........it will be worth the effort when it flowers.....gorgeous scent
