Need to see if anyone has any idea what else I can do to get this thing to get a spark.
The pcm was melted
Replaced pcm
No spark
Coil crank sensor cam sensor replaced
No spark
Replaced alternator
No spark
Pcm still not sending signal to coil
Auto shut down relay replaced
Still no spark

Any ideas of where to go from here?

 

What engine?

 

5.2 v8

 

Getting 12 volts to the coil? (you will only see power there for about 3 seconds if the PCM doesn't see the engine turning.)

 

Yes we are

 

Crank, cam and sync up signals all showing good
No pulse to the pcm

 

Need to test if you are getting ground signal from the PCM then. Can do that with a test light. Just plug it into the coil connector, (disconnected from coil...) the light should flash while cranking.

 

Bad PCM?

 

PCM has been replaced twice so far

 

No ground signal to the coil from the pcm. We have replaced the pcm twice with new and still nothing
