Nissan Repair: No spark Nissan, mass air flow, mass airflow sensor

Question
86 1/2 4x4 Z24 - I bought this p/u when it would only run at about half throttle, and now I assume it was running on the exaust coil. Now there is no fire from either coil. The ECU gives a code 12, 32, and 34. Mass air flow is first. Would a sensor cause it not to send a fire signal to the coil?

Answer
Gerald,

Code 12 Mass Airflow Sensor means it is out of range and needs to be replaced.  You can check the wiring and connector for this.  Code 32 is the start signal and that leads me to think the distributor is contaminated with oil on the optics and needs to be replaced.  Code 34?  Don't know this one as the only thig close is a code 44 and that means all is ok.  Email me back if you need more.
