You can plug the spark plug hole with your finger as you turn the
motor over by hand and feel when the compression stroke is (air will
come out).
I don't know all your details but was the motor pulled from the truck?
Sometimes if you are pulling a magnum and forget to remove the crank
sensor it can be damaged when you seperate the bell housing. Happened
to me. Something easy to check.
Also check the auto shutdown relay in the underhood fuse box. Mine
blew once and the truck wouldn't start. You can also check for spark
by cranking the motor with one of the plugs removed, just keep the
plugwire on it and watch for a spark (you might have to ground it to
the block while doing this). Anyway, just some things that come to
mind.
