Reminds me of the reverse rotation on a Pontiac motor distributor / firing order. I was a Chevy guy for the first ten years of my car antics, then I turned to Pontiac and after my first cam swap, I was scratching my head for at least an hour trying to figure why the car wouldn't start, ... even though I "Seemed" to have the firing order correct (it was just in reverse that is !).
Once, and only once you make that type of mistake. Glad you got your situation figured out ! Life has a lot of lessons, some have to be learned the hard way, unfortunately.
Good Luck from this point on !
