just put a motor in, went to turn it over with all sensors replaced and got no spark, replaced coil, ignition module, cam sensor, crank sensor, tested all wires for cont. - went by the book and looked to see if there was a pulse signal, no pulse signal but each sensor is getting the proper voltage. i dont know what to do now

Did it run before or did this happen during the engine work?

i got it fixed, if the timing chain is off just a hair or loose just a hair the motor will not start in these trucks

Yep, basics as usual!
