I have a starting issue with my STS. At times (when it wants to rather) has starting fits that can last, at maximum to date, 9 minutes. I got the car where the previous owner took a couple of resistors and tied them in line with the wires for the anti theft system or chip in the key. I found a lick cylinder at the wrecking yard with its respective key in it. I installed it in my car, hooked up the wires for the anti theft system and hoped it would start, but to my dimay, it did not. I am worried that if I get one off of ebay that I will have this same problem. Do I have to take the cables off
