follow this link and go through the whole no start diagnostic. I have used it multiple times and it has always found the correct problem. Best of luck!

In '96 an improved coil was put in, at least on the Caprice LT1 I am familiar with- it was used as an upgrade for older Caprice/Impalas, and yes, a different plug-
I would think that an ignition switch is a possibility- the run circuit and the crank circuit are different parts of the same switch- Can you hook up a hot-wire to the coil, and see if it will run that way? Might be a quick diagnostic test-
And, since there is no spark, you might have to start chasing down the one or two security systems that you have- either one could be disabling spark to prevent theft- Lastly, the circuit in the ignition switch that uses the 'pill' or resistor in the key- if that goes bad, again, no spark-
I would hook a jumper from the battery to the hot side of the coil, in effect, turning the ignition on, and see if it fire then-

If the Key resistance was incorrect wouldn't the "security" light come on???
I'll check that out as well and if no luck with the "jump" then....
..I'll be back.
Thanks,
Ivan
