I purchased three tomato plants with blooms. I now have a few tomatoes, but no new blooms. What can I do?
If you haven't planted them yet, then do so. If these are planted, then there could be a few issues. If it has been too dry, OR too wet, then both can cause the issue.
Not having the proper nutrients in the soil can cause this as well. Either too much nitrogen, or too little phosphorus and potassium will be to blame.
Temperature can also cause issues.They need to remain pretty steady in order for the plant to fruit properly, as temperature fluctuations greater than 10 or 15 degrees will halt flowering in many cases.

Why do my tomatoes split open right before they are ripe?
This usually happens with uneven moisture. When it is hot and dry for a period, and the plant suddenly receives moisture they will split.
It is necessary to maintain constant moisture during fruiting for the best fruit set.

When this first occurs what can one do?
If the manure is not well composted, then this is certainly the cause. It contains way too much raw nitrogen in a form that is not useful to plants. This will cause nutrient burn. You will have to remove the manure, and replace with compost, or composted manure.
The rest of that nitrogen will have to leach out of the soil naturally. It may take some time, but it will happen naturally.

After starting to produce, the plant dies from bottom up
This sounds typical of magnesium, calcium, phosphorus, and potassium deficiencies.
I recommend adding a HANDFUL of DOLOMITIC LIME per plant, and adding a bloom booster at half strength.
You can also amend your soil with compost, and dolomtic lime. This will have a similar affect.
If you can include photos, then I can rule out fungal infection, and conclude what is going on here.

I did some very heavy pruning of tomato plants. I watered them heavily after pruning. Is there anything I should be looking for now that would suggest I did too much cutting?
Pruning of tomatoes is covered in the articles below.

There are hundreds on my tomato plants but they don’t seem to be causing any noticeable damage. They are light black and have wings but they tend to just walk around when poked and are very easy to kill by hand. They’re not attracted to any other plants either.
That is a tomato leaf miner. It is definitely doing damage to your plants. This article will help: https://www.gardeningknowhow.com/plant-problems/pests/insects/leaf-miner-control.htm
I pulled up and destroyed tomato plants affected with curly leaf caused by what I believe to be a virus. Can i replant with new plants in the same soil or must I move to new location?
Curling leaves on tomatoes can be caused by a virus but there can be other causes.

Crop rotation is very important in growing tomatoes.
