Many thanks to all that replied. In all honesty I used to own this house some 16 years ago. I gave it to my wife in a divorce. Due to her health conditions, she was not able to keep up the maintance or the payments.
I took it over from her just two months ago, not realizing all the problems, I just did not want to see her lose it in foreclosure.
Anyway, in regards to the mositure in the crawl, it is now much worse than that. There is one spot in the middle, about 15 feet from the foundation, where a actual hole was made from the force of the water. The ground there is higher than around the foundation. This week end after draining it again with a 6 gal Shop-Vac and carrying the water out doing a duck walk, about 30 times, I started digging out the hole to enlarge it in order to place a sump pump and pit. The deeper I dug, I could push my hand down and feel water. ( I wish I could send some one a few pictures in order to get your ideas of what is causing this and get some more recommendations)
The reason I was asking about the extension cord,is I am not sure if I want to keep in where it is or not. Also, This house has drained me dry aleady. (No pun intended) I know nothing about electrical work. That is why I wanted to use and extension cord since there is already an outlet down there. Not GFI, just a standard one. The pump will not run in automatic mode, but it will using just the one wire alone.
I think I will check out the extension cord with the GFI built in, as mentioned above.
Thanks again to everybody, and if someone could explain the mysterious hole in the ground, please let me know.
