    Might you have mixed up some electrical plugs when doing the head work ?

    Check you are getting pulses from hall sensor at the distributor (5V LED on the middle pin wrt 0V should see pulses every 2nd crank rotation) and of course check twice that the mechanical alignment of crank, camshafts and distributor is as it should be

                With ignition on you should see steady +5V across the outer two pins at the hall sensor plug. If you don't have that, the engine will never start.

                Have a check that all the fuses are good just in case.
