I just did a timing belt change and ran into a major "got ya". After everything was finished, checked and put back togeather, I had crank but no start at all.

Turned out to be a miss-build in the factory. The intake cam sprocket was put on 180 degrees out so when I used the timing marks to install the belt, that put the intake cam 180 degrees off. The factory must time the engine from cam position, not cam sprocket position.

When the sprockets are in the correct position, the dowels on the cams should both be up (under the washer). On mine, the intake cam was down and the exhaust was up.
