Mike: Your Yukon, like many newer vehicles, have a taillight circuit board that the bulbs and wiring harness plug in to. Vibration, moisture, and age sometimes cause the circuit board to fail. If you replace a brake or taillight bulb and it still doesn’t work, this is where I would look first. Luckily, they are usually less than $15 and are relatively easy to replace. I have replaced dozens.
Ed writes. I have a Subaru WRX-STI with a manual transmission, and I love it. It is the first 300-hp STI version sold in the US in 2004. I am the original owner, and it is in pristine condition. Do you think this is a future classic?
Mike: It is absolutely a future classic, so hold on to it. The STI (which stands for Subaru Technica International) models are great to drive. The manual transmission adds value. What else adds value is keeping it stock, in other words, no modifications. If you do make any changes such as wheels or exhaust, KEEP YOUR STOCK PARTS. That is very important to a collector to be all original. The WRX-STI is on everyone’s list as an affordable future classic. Good Luck!

When it does this, I can go back later (or have it towed in), and it starts wonderfully! The problem is that it runs fine for days or weeks until it does it again. It has been tuned up and also had a new fuel pump last year. Mike: While I am not there to diagnose the problem, let me give you my best guess. GM used an anti-theft feature called Passlock for several years. Passlock utilizes a special lock cylinder that stops the engine from getting fuel (and running) until the proper chipped key is detected. Sometimes, the Passlock feature activates without any reason, making you sit and wait out a 10-minute delay. I have many friends that have gone on the internet and found the exact procedure to bypass the system. Several YouTube videos are online showing how to do it. Good Luck
