Dodge Dakota Timing Chain Replace/Remove

Replaced All Three Timing Chains. Had Everything Lined Up Correctly But When I Rotated The Engine 7 Revolutions Both Cam Chains Are 1 Tooth...

Do I Need To Change All Three Chains Or Just The Main One?

My Car Runs Fine But I Would Like To Know When I Should Take It In To Have My Timing Chain Replaced I Know On Toyotas It Should Be Replaced...

I Have Changed The Timing Chain And Gears, But My Dakota Still Wont Start. We Drove It To Town And Turned It Off And It Would Not Start...
