i dont think your problem is fuel related. you need to start from the begining again
let us take the initial cause of the problem. the alternator blades broke up and hit the lobe on the crank.
although it is highly unlikely did the shrapnel do any other damage like puncture a loom on the chassis leg or hit the coil area wireing. i can only assume that a blade jamed between the crank pulley lobe and something else in order to break it off.
the fact that you have white smoke comming out the turbo inlet indicates that some ignition is taking place with the inlet valves open or slightly open (ignition problem)
or that compression is taking place with the inlet valve not fully closed (valve timing problem)
seeing as you are very confident that the valve timing is good
i would concentrate on the fact that you only have a spark at number 1 plug. i know its obvious but you will not be able to fully diagnose any other problems if any, until all 4 plugs are sparking
if the car was running perfect before the lobe broke off then the simple solution of replacing the pully should have fixed it.
i know i am not offering any quick fix at the moment but i would suggest that you start from the begining with the basic cause of your problem and go from there before you start going off the track and trying to fix problems that you may not actually have
