My cucumber plants are loaded with blossoms but no cucumbers are forming. Also, I planted pumpkins and the seedlings are about three inches high but have stayed that way for weeks. Why?

The cucumbers may be having pollination issues, especially if it's been overly hot/humid or rainy. You can help it along by hand pollinating the plants. This article will help: https://www.gardeningknowhow.com/edible/vegetables/cucumber/hand-pollinating-cucumbers.htm
As for the pumpkins, it may also be a fertility problem. I would suggest getting the soil tested. Also, check the amount of sunlight in which the seedlings are receiving. Here is more information on growing pumpkins: https://www.gardeningknowhow.com/edible/vegetables/pumpkin/pumpkin-growing.htm
