96 sierra 4x4 5.7, no spark, no fuel, only have .4 volts at ingition module, coil, and 10A ign fuse. Door locks don't engage when turn key,

Something wrong in the fuse box if you only have .4 volts at the fuse. Maybe a loose terminal in there.

Car wont start no spark at plugs

if distributor model check coil feed to distributot for spark this is done by grounding the coil wire. if coil module feed then check power to coil module if no power then your problem is outside the engine area in the ingition or fuses ect many possibilities

No fire from ingition coil

are you saying that you have 12 volts to the coil but no spark out/if this is the case first make sure the cam is turning by looking in the oil cap hole,next yes the cam sensor is a common failed part and can cause the problem, you also have the crank sensor just below that and it would not hurt to replace also
