90 240 ignition timing problem

    I just finished laying an engine into a 90 Volvo 240 wagon.

    It runs for two minutes, will not restart (no fuel pressure). I
    replace main relay. It starts now.

    The base timing (non-adjustable EZ-116K ignition) seems to be about
    ~45-60 degrees BTDC which is way advanced. Idle staggers and spark
    knocks badly while driving. It runs for 15 minutes, will not restart
    (no spark).

    I replace the flywheel/crankshaft ignition pickup, it starts now with
    the same ignition timing problem as before.

    I made a point of indexing the flywheel/flexplate to the crankshaft
    when I swapped it onto the new engine (92 240), so that it was aligned
    as it was on the old engine. There is a small possibility that I
    wasn't paying full complete attention, was smoking crack cocaine or
    something, and have the flywheel/flexplate w/ hall effect wheel
    misaligned. I really can't see any other possible cause of my
    problem, and I don't really want to have to yank the transmission to

    Any Volvo gurus out there care to speculate? Thanks.

    position of the crank sensor will make the timing more advance or retard.
