How did you check for no spark?
It was running fine before right?
Here are some things to check

Is the ground strap connected to the valve cover?

Most ecus will cut spark to a cyl (or bank) if its misfiring badly enough to damage the cats ( which have an 8 year/80k warranty )

If you did the same thing I did, youll notice that after attempt, one exhaust bank will be cold, and the other will be warm. On the bank 4-6, the intake manifold will be warm by the head.

If thats the case, you set cyls 1 and 4 on on the compression cycle when you set the cam timing, instead of cyl1 on compression and cyl4 on overlap.

With the engine in the car, you can remove the valve cover for cyl 4-6. Loosen the cams, sprocket, chain and tensioner. Make sure the cam isnt pressing down on the lifters.

Rotate the engine 360deg. Thats just ONE revolution. Bolt the cam back in place,and set your timing again, put the cover on, and start the car back up.
