So the new distributor arived today, it was a cheap part to throw at this but i figured i would try. Still get the code. The old one was in bad condition anyway but i figured out that you CAN rebuilt them. Not sure why the parts are not available.
A new distrib or rebuilt is a good thing on old cars like this. we can not burn fuel (gas) with bad spark. A good IDEA new distrib.
I do see the sheathing on mine but there is nothing around to create signal were the sheathing is not on it.
I looked all over for where it might be grounded in the engine bay and near the ecu but i cant find anything that looks like it.
Sadly I have no X90 ECU drawings, and are very hard to find on this rare car.
The 96 tracker pins are pin 16 and 17, and are colored. org-blue (means orange with a blue strip(ignore dots) and White-blue.
maybe the x90 uses the same colors, there is a good change it does.
the org wires are not common, that color is very unique on our ECU pins.
The harness was ran right over the alternator so i moved that so its not near it.
Thought this might fix the problem but it did not.
That 2pair wire to CKP does in fact go into the main harness, in the engine bay then does in fact go Through the fire wall, and into the dash board
hardness and does arrive at the ECU on those 2 pins named the same (CKP pair)
this long run of wires does in fact go past vary electrically noisy circuits!, and in fact the shield on that cable (not there for fun) keeps said noise out of the ckp pair, both inductive noise (magnetic) and capacitively coupled noise.
all you saw as the short pair, the trip to the ECU, is a long trip, meandering to the ECU, and was shielded cable, for very very good reasons.
there may be connectors in that long path that are not documented anywhere on earth. (harnesses are very complex)
try to consider 2 facts. (the CKP is now too far from the tone wheel, pan gasket stand off)
the CKP signal will be weaker, for this 1 fact.
and now the ckp signal to noise ratio will be much poorer for sure at low idle speeds.
My next move is the run new wire and then i am all out of ideas aside from replacing the ECU.
do run only 2 pair shielded cable. with only the ecu end ground to the shield just like suzuki did.

things that make noise. in cars. 101.
the alternator makes huge noise, and even more noise if 1 of the 3 phase output diode rectifiers are bad, or omg worse shorted.
with the radio on AM and off station (between) hear the whine of any alternator for sure bad, or not quite right, but still charges battery.
all ignition both primary and for sure secondary HV side makes tons of noise.
the AC clutch kicking in and out , omg noise huge, if you have AC .
The wiper motor noise. (blower fan in dash too)
about the only thing quiet in cars is lighting of any kind stock.
also I bet no 2 harness ever made even same year have wires laid down inside the same, so some may be more noisy that others. (luck of the draw)
they are hand made those harnesses.
some have crimp connectors not documented in the middle of some harnesses. (Y- crimps , or ground wires tied all together crimped then go to car body with a ground lug. (if loose oh boy, trouble)
