92 Nissan PU KA24E engine no spark, what to shotgun ?

This truck occasionally and only briefly won't produce a spark Since it never cooperates by not producing a spark long enough for me to track the problem, I've decided to just shotgun it and replace everything that has to do with the spark.

OK here's what I'm thinking constitutes all of what should be replaced to consider the spark aspect of the engine to be fully "shotgunned"

Firstly, the ignition coil has already been replaced, so the remaining items should be,

  1. the transistor that drives the coil
  2. the computer board
  3. the sensor inside the distributor

Anything else I need to add to this list ?

Thanks in advance Dave

That would be the ECM,VERY expensive,and probably NOT NECESSARY.

did you bother to get the ECM read for trouble codes? That is the FIRST thing you should do.

distributor cap,rotor,plug wires(they can break down with age)

and spark plugs.

you can download sections of the Nissan manual,1 per 24 hr period. I can't recall if they go back as far as your year of PU,though.

Thanks. Unfortunately, I wasn't able to find anything there before 1994

I downloaded the EC manual for a 1994 and so far it looks like it might be the same as my 92, or at least close enough to be useful.

If nothing else, it does explain a lot of the Engine Control theory, so if nothing else it should be a good educational read.

Thanks for the link Jim
