grounding plug question

My power to my pool pump is not working. In the garage I usually connect a plug/power line to a garage outlet. This power line runs to the pool The plug usually has a grounding plug adapter...the one that has the little metal thing on the bottom. I misplaced it this winter, so I plugged the cord in WITHOUT the grounding adapter and no power to pump. Is it likely the missing grounding adapter thing is the reaon I am getting no power. The outlet itself in the garage has powerb as I tested it and it works fine. Only other possibly is the pool outlet itself is damaged or somehow disconnected. , but I put in a new outlet last summer there. Anyways, I am not an electrical whiz. Any comments welcomed. The missing adapter seems like the obvious possiblity. I assume it needs this to be grounded correctly. I did not do the work, previous owner did it himself.

I'd suggest you buy or borrow one of the cheap testers found in the hardware electrical department. They have three little lights on them, usually 2 green and on red.
You plug the tester into the first outlet. if you have 2 green and no red you are fine. plug in the next plug and move the outlet to the next outlet. 2 green on and you are fine.
If there is any other outcome it is time to call in qualified help.
Using the ground lift adaptor on power to a pool is NOT a good idea.

Its *possible* that the neutral broke somewhere between the garage and pump and some jackleg used the ground to complete the circuit, but its really impossible to say for sure without much more info. The best anyone can do is to say that you REALLY need to have this looked at by a qualified electrician.

Definitely, get a licensed electrician to fix it. Don't screw around especially with a pool appliance even if you are sure you can fix it. If you have to ask questions it shows you may not know enough about it and you could create a big liability for yourself should someone get injured or even killed. If anything should happen even if it is not proven to be from an electrical fault, your insurance may be in jeopardy or worse. The last thing you need is a law suit claiming an amateur tried to fix the pool pump.

You could check it with a receptacle tester and it will indicate any type of fault., but, you have not mentioned if it is even GFI protected. It sounds dangerous enough for me to tell you to have it checked out by a qualified person asap.
