Mr. Resourceful
If the coil has power to it and you're not getting spark, that sounds like a bad coil.
Can you give us some more info?
When did this start?
Has the car been sitting or did it die while driving?

Just because parts are new does not mean that they are a) good and b) properly installed.
You're going to need to do some in-depth diagnosis to see if you're getting the CPS signal and if the DIS is firing properly.
most common failure in the scene you describe is that the new crank sensor was not gapped properly and has been destroyed because of that. are you absolutely certain that the crank sensor was gapped properly?
I did not install the crank sensor, I just boughtthe car non running for a steal so I am starting with what I know. I do know the Crank sensor was replaced although I dont have that much faith in the genius that installed it so it may be junk now. It does have a leak at the fuel pressure regulator when you crank it over the feed line is leaking where it enters the regulator. Not severly but it is leaking. That wouldnt do it correct ? So HOW do I test the Crank sensor ? Greatly Appreciate the help !!!
The guy I bought it from said one day it just wouldnt run, ran the night before but the next day wouldnt start. I checked for loose wires, I was told a ground wire could also cause this issue ? I dont see any loose. How Many Ground wires are there on this that may impact it running and where are they ? Appreciate the help !

The DIS module on the intake is grounded via a strap at the back of the intake, to the firewall. If that strap, and the brackets that attach the surge tank to the rest of the intake are questionable, or missing, then you would experience the issue that you're describing to us now.
Check those connections and get back to us.

It needs to be around .030" - but the way the sensor is made it wants to be larger than that because the magnet is in the top part and it wants to clamp to the shutter wheel, which results in a dead crank sensor. So you need to verify that the gap is not too large.
A matchbook cover works pretty good for a thickness gauge in this instance.
