03 Montana No Spark

[grandamle91]

I've just did a top end rebuild and everything went good but went to go start it and it just cranks. There's fuel, injection is spraying. But no spark. Had the ignition module tested good. Crank sensor in the block read 950 ohms, .5 to 1v ac when cranking (New) PCM shows it is cranking at 200 rpms.



So I'm lost. I had it running last night. Then went to move it and back to what it was. Ran really smooth when it did

go back over every electrical connector you had disconnected looking for a bad pin, wire, etc.
