New inition coil...new crank position sensor...no spark...has fuel...was told to update the harness to the coil...did that...no spark...might be auto shutdown relay...cant find a test for it...any ideas?? Once in a while the i/p cluster goes dead and no bus appears in the odo box...temporary...it clears itself...also before the failure the engine would begin to run rough...if the car was shut off...when restarted it ran fine for week or so...then it would do it again.

 

Any codes? Is the harness to the CPS fried? What's the fuel pressure in psi? Coil pack no distributor right?

 

Connections and grounds.

Regarding your ADS relay question: you can swap it with a known good relay in the PDC to verify.
