No spark

Question type: Maintenance & Repair

Recently got the truck with a fresh motor
and trans out of a identical year truck.
Motor was rebuilt now it's installed but not
getting spark.. Changed the coil, plugs,
wires, distribter , crank position sensor.
Has power to where it needs to but no
spark or pulse ( tested with led test light).
I'm totally stumped on what to do and
what the cause could be. Please help

I was under the impression that a computer couldn't be read without the motor running cause it will only read what codes was stored in it from the previous motor
