It rolls over, the fuel pump comes on but no spark to the plugs and no
pulse from the coil. Power side of the coil is fine.. the other plug has no
activity while rolling the truck over. I am assuming it is the ignition
module but wonder if it may be something else.

Took me a while to figure out that this was not a Jeep with an engine swap
but
rather a Canadian marketed Chevy product.

According to what little I found, it has pickup coils and an ignition
module.
If either coil or module, or their connecting wiring,  is defective, you
will have a problem.

People who know these engines well can probably tell you if there is more
hiding out
under the hood.
