 We went to AutoZonePro.com and discovered that AutoZone had a Duralash crankshaft sensor in stock. We typed in, deliver, hurry please, and boom. Shortly after that, we looked at the tracker and found that the crank sensor was on the way. We washed the rest of the mud off the engine, and while we were at it, we washed the whole Jeep. Then we installed the sensor, and boom, the Jeep Wrangler fired up. Briston paid the bill and took off with a great big smile on his face.
