Default no spark 1997 5.9 1500

ok guys this one is driving me nuts
i swap out my 1997 ram 1500 5.9 engine with a 2001 ram 1500 5.9 i installed a new coil new crank sensor and cam shaft sensor and change a few other sensor form old engine to the new engine and still no spark


i have tested the asd relay and changed it just in case and checked pin 30 i have power there

when i put my test light at the coil no power at all when cranking over i have tested the 2wires from the pcm to coil to make sure they dont have a break or shorts and still no spark


any ideas and help would be great and there is no cel on and the light does work

thanks james

Then you are having an asd event.

Grab yourself a buddy. Park buddy in drivers seat. Get your meter out, and insert one probe into the power feed for the coil, ground the other probe. (meter set on 20vdc) Have buddy turn ignition to on, but, not try to start the truck. You should see power there for about 3 seconds. (a test light will work too......) Light should blink on for a few seconds, then off.)

Got all the ground wires attached properly? Like the 2 that go by the power steering behind the water pump inlet tube?

Two on the front of the motor, by the power steering pump. Also ground wires at the back of each head, to the body. (I think)

I could be wrong, and I'll look in the morning(at my truck for you), but doesn't the negative from battery go to the alternator? (the thick one) and a thin gauge one goes to the radiator support.
