Electric Problem

My Relay Integration ( fuses holder under steering coloumn ) is making a buzzing, like it having an electric shock but when I turn the key to on but not initially started yet the Relay will stop making the buzzing so I don't know if my Relay Integration is bad or wire circuit somewhere and when I checked the wire harness using a wire cuicuit tester to test on the TPS and MAF connector they gave a very low light so is this normal? I checked the under dash wiring and it seem to be in good shape, everything work fine from the back lights and front and window, lock work fine but the signal will not work when I enguage so I guessing it is my relay is bad or the steering itself, your input will by apeciated, thanks!..

Does it make the noise when the key is removed?
If so, the ignition switch may be "sticky" tap on it with out the key in.

it turn out to be a bad ground, I clean the corrosion that connect to the engine block and now it has stop the electric buzzing on the relay and solved the key issue that the key kept getting stuck inside, it was the solenoid that connect to your ignition is burnt well that is a $65 part. This what I get for an 212,000 miles truck... it really need a tuneup, previous owner is a elderly man whom is not a car minded person so I purchase from him and have drove it only 2,000 miles and it died on me so it stay in the garage for more than 3 months and ended up opening the whole dash board and fender which is a pita and it turn out to be just the damn ECM, stupid me lolz so I convinced that I'll get it fix by this month or next, and I'm not really a mechanical incline person but somehow I sometime get luck to find the problem is and alot of help from your guy's too very appeciate for that, thanks!
