One day I came home from work, vehicle working fine, went to leave again and car would not start. Have a computer reader and 20 years of experience working on vehicles the computer said crank shaft sensor. After replacing that still nothing. Local mechanic suggested the cam shaft sensor. Still nothing. After lots of suggestions of timing chain and other sensors and days of headaches my brother and I finally found the problem. It was corroded wires to the fuse boxes. After fixing them it started right up. Just wanted to give someone else some advice never thought to check the wires to the fuse box.
