Which vehicle?
Never buy parts on speculation, pretty much ever! Take out tools before you take out your wallet. Find a way to test a suspected part first. For a starter, just jump the solenoid connector to the main feed (key off, so it doesn't start while you're under it).Sorry for the late reply, yes, battery is fine. I ended up taking the starter out and bought a new one. That didn't work.
Well, I did that, the solenoid didn't engage so I thought it was the starter, then took it to be tested at AutoZone, if failed. I was referred to a different store to buy a new one, I thought screw it, lets test it again, might as well, it's free. So i had it tested, and it passed, 3 time back to back. so I went back home and installed it and the solenoid was not engaging again, went and bought the new one, installed it and called it a night. I just got off and showered, ready to get dirty again. When I crank the key to start the car while under my jeep I hear a whirring but its not the starter, the starter isn't even engaging, it has power but wont turn, either on the new or old one. I tested all my fuses last night but they all passed except one for a light, which I replaced.Never buy parts on speculation, pretty much ever! Take out tools before you take out your wallet.
