There are no timing marks on this motor. The timing has to be set with a special tool that holds the cams in place, as the timing is variable and held in place by the bolts that mount the gears to cams. If you loosened any of those bolts, you'd need the tool to get the timing back in place.
But if you didn't mess with any of that, and just replaced the tensioner, then my guess is somethiing like a sensor, maybe the crank position sensor?
Do you have spark? Get an old plug, pull a plug wire and see if the old plug sparks when you crank it (lay plug so its touching metal, so it has a ground). If no spark, I'm guessing its a sensor not connected properly.
If you've got spark, didn't mess with the chains or gears at all, and have fuel getting to rails, then um, I give up. But did you check fuel? Sure you're getting fuel to the rail?
One last thing? Still have your old tensioner? I need it, even if its in pieces. I'll pay for shipping of course.
