200tqa '89 MC2 has intermittent starting problem which gradually
developed probability of the failure from 0 % to 100% within last 2
weeks. I checked coil power stage and coil per Bentley and one test
does not look as ok: voltage across pin 3 and 2 on power stage
connector is changing all the time when I crank engine. I saw 0.0,
1.3V. It is just what I caught. There were some other numbers. Bentley
says at least 0.2 V. Should it be stable or fluctuating? Wire between
ECU pin 22 and terminal 2 on power stage connector is ok (0 ohm).
Bentley says: amen, change ECU. I would appreciate any recommendations
before I start to look for MAC-14?
P.S. I did not check fuel pump relay but at output test fuel pump runs.
Therefore I assumed that relay is ok.
