F150 timing chain change now won’t start.

If you mess the timing up on those overhead cammed Fords it is very easy to bend valves. If it ran before you changed the chain the problem is something you did.
If the marking are dead on then what could I have done wrong?
Does the engine turn when you try to crank it? Did you turn the engine a couple of revolutions in the correct direction by hand before putting it back together. Did you replace the tensioners? Did you replace the rubbing blocks? Did you leave any sensors unplugged like the crank sensor etc. Also from the pictures it looks like the chain is dirty and has sand on it.
Did you figure the issue out I’m having the same problem with my 2005
I forgot to put my Ignition Pulsator Crankshaft Sensor Ring back on after doing the timing chain, wouldn't fire at all.
