Played with all the fuse tricks to fix radio but it was the oem amp that needed replacement. Thanks YT and eBay!
Anyone change plugs on a GM 5.3 truck? Plug #8 is buried. Youtube has various suggestions including removing the tire and shield and going through the wheel well/ Trying to avoid that, cause lazy.
2 outta 3 ain't bad.....
One spark plug is all you need.
could always do the @Patrick method and use the most versatile tool he has, one which has never failed to solve the problem 🤣 (credit card)

More on the Tiguan problem. Looks like the tensioner failed and caused the timing belt to slip. Some mechanics think the engine is shot while others think the motor should be fine as the cylinder compressions are normal and may be resolved by replacing the timing belt.

A broken timing belt or tensioner will trash engine that won’t freewheel. Usually they won’t hold compression, but it sounds like you may be real lucky here. 🤞

Many questions without scrolling back for details.
What year, is it an interference engine, belt or chain?
Short Google brings up some answers.

Seems there was a problem with the timing chain but not for my year. Apparently there was a class action suit for many VWs and Audis

Is it an interference motor and is it possible one of your pistons swallowed a valve? This would cause low to 0 compression in a cylinder. The only way I see this happening is if the chain slipped a few teeth due to the tensioner failure and the crank turning over made it hit, but you would have heard some nasty noises when cranking it. Did your child say anything about what it sounded like or just that it didn't start?

No tin can rattle and all cylinder compressions are good

So the mechanic who said it had low compression and needed a motor is out of the picture?
New battery, turns over but doesn't start, good compression, and are there any codes on the OBD?

It was the first mechanic who does basic maintenance for my cars. Said the compression was 120 but should be 160. Though a VW specialist said it was fine at 120. Checking the VW boards it's seems good compression ranges from 120-180. It was measured cold so maybe 120 is fine? No codes, we never saw a check engine light either

Was it the first mechanic who said the chain tensioner failed? Where did that come from and was it verified?
I assume plugs were pulled for compression, any mention of how they looked or if a little ether was sprayed in the cylinders to see if it fired?

Got lucky with the Tiguan engine. Seems the timing jumped while trying to start when cold so it didn't turn over and break valves. Since the cam positions were so far off that's the reason it wouldn't start. A new timing chain kit and a few pieces including plugs and it's back running again. Three mechanics told me the engine was gone including the dealer. Glad to not need to go used car shopping with the kid.
I'm hearing chirping/squeaking noises from my 2002 Silverado. Noise gets faster when wheels spin faster. I hear the noise when rolling downhill w/o stepping on the gas. Seems to be louder going backwards. I should also note that I lifted each wheel and spun them by hand and did not hear the noise. I'm leaning toward a wheel bearing. Any other guesses?
Also, what is the plate behind the brake rotor and do I need to replace it on a rusting out 200k truck that I hope to get 1-2 years out of for Home Depot runs?

Backing plate is optional. Don't worry about it.
Noise sounds like U-joints unless some rusty thing is rubbing on another rusty thing. The version you sent me sounded like potatoes in a garbage can. See if you get a noticeable clunk shifting forward/reverse. Sometimes there will be some rust dust around the joint if it's eating itself.
