Need help and stumped. Replaced timing chain, tensioner and guides and VVT on 07 cx7 and now has a no start. Code p0340 and only one spark and done. Have checked and rechecked timing over and over. TDC and cam tool slides in both cams. Am 98% confident that's that's not the issue. Tested cam sencor with my vantage and has square wave form while cranking. Any ideas please
