No spark

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

Plug into the OBDII DLC port check the codes..have it scanned

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
