Low Oil Pressure help?

[Tx97GSX]

A couple of months ago I had installed a 6bolt into my GSX. Well before I did that my stock oil pressure gauge did not work and I purchased a after market gauge. Installed the gauge and it is still not reading any pressure. I go out and buy a new Oil Pressure Sending unit at autozone and install it after a oil change and my gauge still doesn't work. I now sometimes get the low oil pressure light when it is at idle but as soon as I rev on it, it goes away. I know that I should have plenty of pressure since the block itself only has 1000 miles on it, and it also has the balance shaft removed so I should have more oil pressure then normal. So do you guys think that something electrial is wrong? I did a test and grounded the wire from my aftermarket oil gauge that connects onto the sending until and when I would shut the door, my gauge would jump to a random number and stay there. It will move every once in awhile. Any suggestions would be great.

You can get mechanical oil guages that you thread into the sending unit hole to check oil pressure. Try that - it'll tell you where the problem resides.
