Sounds to me- If you have fitted the belt as the marks on the out side of of the wheels eg the info Rossco posted the cam timing should be good !
just check that again covers off hand rotate the engine until it all lines up again

If the cams were set ether open and closing times or lobe center don't play with that ! as that would have taken some time to do

So the air gap at the cam sensor - usually it just will not run but check it
Crank angel sensor failing - will give the fault you are describing
So if you can swap it with a friends to test it out

very easy to do one bolt and a plug

also check the wires as the insulation fails due the heat at the crank and cam sensors
