No spark for hot start - '90 200tqw

[Konstantin Bogach]

I had intermittent hot no start (which later developed to total no
start) condition.  I
found it was bad TDC sensor on fly wheel.
It looks like wires connection where they go insid of the sensor is
bad.  Find connectors
just on the left of igniton coil. You will see vertical row  of
connectors (for TDC, RPM,
nock sensors).  TDC connector is black, top most one. Disconnect it,
measure resistance
across pin 1 and 2. Should be around 1000 ohm.  I had infinity at no
start condition. I
moved wires at sensor and it became 100Mohm. Moved more and got 10Mohm.
It let me start
the car. I drive 2 days in this state. No problems while I am looking
for replacement.
Resistance across pin 1 and 3, 2 and 3 should be infinity.
