So I just got finished replacing the timing chains and tensioners on my 01 S-Type 4.0L. Everything went smoothly. Used the lock down kit to set the cams in position and the pin to hold the flywheel after taking out the crank sensor. Put everything back together and now having a crank, no start issue. Have checked for spark and it's sparking, all 8 spark plugs are also new. the engine seems to be getting fuel on all 4 cylinders on the passengers side (those plugs are wet) but the drivers side 4 plugs are completely dry. I also noticed the tach is not moving at all. Just stuck at 8k all the time. Any idea on what I might have going on? There are no DTC codes what so ever.

 

I don't know. But I think the 4L S-Type engine and the 3.2L X308 engine are similar - below is my writeup of my X308 timing chain replacement - maybe, if you go thru it, you stumble across something, which might give you an idea:

PS: And here is a far fetched idea: Not long ago I drove 90km distance with my X-Type, reached the destination and right at that moment: Crank, no start. I had to get towed back home.
What, if your crank, but no start issue is not connected to your timing chain replacement at all.
Maybe it is the same problem my X-Type had - I figured that one out fairly fast: Sudden death due to suddenly blocked fuel filter. I swapped the fuel filter and all was good again...
