I had an ignition switch that intermittently and distinctly did not supply
'15' power during starter cranking.
This was in an 87 Syncro Doka with AAZ 1.9 TD engine.
it would crank just fine, and had that syndrome where if you just let off
the 'start' position back to 'on'...
and catch it just right...the engine would still be turning a turn or two
when it got that '15' juice from the 'on' position in the ignition switch,
and it would fire up.
A new ignition switch fixed it just fine, so 100 % certain it was a bad ign
sw.
So might check that '15' voltage is present during starter cranking.
or try the 'catch it just right' method.
or just , as suggested, quickly plug in another ign switch and operate it
with a screw driver.
