| Dear Customer,|
This year will go down as one of the most hectic times in modern history. But the good news is, the holidays are finally here to bring a bit of joy and wonderment to an otherwise chaotic year. Why wait any longer? Let’s break out the eggnog and let the festivities begin—we deserve it!
One thing that’s on everyone’s mind during the holidays is gift-giving. Trying to come up with that perfect something for that special someone can be a daunting task. To help out, in this month’s newsletter, we’re discussing gifts that gearheads (like you) can give their loved ones. Fixing or upgrading someone’s car is a great way to show them you care.
Planning on traveling this holiday season? Then you'll want to read our article on safe holiday driving during the COVID-19 pandemic. Even though the holidays bring much joy, the virus is spreading in many locations, and it's important to take extra precautions to stay safe.
We’re also excited to give you a first look at the Naperville North Auto Tech program, where Career Technology Teacher Greg Ditch and his students have been hard at work restoring a 1995 Ford Mustang GT. CarParts.com is proud to sponsor the team as they work together to get the Mustang back on the road.
Last but not least, we have our monthly Auto Shop Pop Quiz, as well as the latest updates from NASCAR Cup Series driver Michael McDowell and the No. 34 CarParts.com Ford Mustang team. We’ve also included an exclusive 8% coupon to help out with your holiday shopping.
With all the best wishes,

| The holiday season is going to be a bit different this year because of COVID-19. In the past, you wouldn’t have thought twice about loading up the kids and heading to Grandma’s house. But now, you have to reconsider your travel plans. Stopping for food and lodging along the way can be intimidating, and so can the thought of spending time around loved ones who might be compromised. |
We asked our followers whether they were still planning on traveling for the holidays, despite COVID-19. Nearly 8,000 people voted, with 75.8% of respondents saying no, they will not be traveling for the holidays. Meanwhile, 24.2% said they still plan on traveling this holiday season.
| A vehicle cranks normally but doesn’t start. Which of the following could be the cause? |
| D || A failed crankshaft position sensor (CKP) |
| Scroll down below to find out the correct answer. |
| Correct Answer: D |
| The correct answer is D. There are two primary types of no-start conditions: no-crank-no-start and crank-no-start. In a no-crank-no-start scenario, the engine either doesn’t turn over at all, or it sluggishly tries to turn over but cannot. On the other hand, a crank-no-start condition is when the engine turns over, like normal (or faster than normal), but doesn’t fire up. |
Each of the two conditions has a distinct list of potential causes. A no-crank-no-start condition usually points to a problem somewhere in the starting system (i.e., battery, starter, etc.). A mechanical problem that prevents the engine from turning over is also a possibility.
Meanwhile, a crank-no-start condition usually points to an air/fuel delivery issue, a lack of spark, or a loss of compression.
Answers A and B are wrong because a dead battery or a faulty starter would prevent the engine from cranking normally. Answer C is also incorrect—a starter motor can’t crank an engine that is seized.
That leaves us with the correct answer, which is D. The engine’s computer, often referred to as the powertrain control module (PCM), relies on the signal from the crankshaft position sensor (CKP) when calculating vital outputs, such as ignition timing and fuel injector timing. A faulty CKP can prevent the engine from getting proper spark and fuel, resulting in a vehicle that cranks normally but doesn’t start.
