I replaced the following items, still no fire.

Ok I have replaced the DIS module; EEC; Coilpack; and CPS, But still my SHO won't fire. It will turn over but it will not produce fire at the coil.

I have spent about $500 in the last week trying to trouble shoot this. I can't get codes because the car won't run. Or is there a way to find out what it is. I am very tired of replacing parts and am starting to get VERY downhearted. I'm starting to think my SHO will never run again.

HELP ME PLEASE!!! shoot

Where exactly does the juice trail stop? Before or after it gets to the coil pack? You're going to have to trace the power and or grounds back. You are positive that there is not spark at the plugs?

Yep. Could be a bad connection. Does the EEC get power when you turn the key to the "on" position? If so, then the check engine light should come on and you can pull the stored codes.

The wiring harness that goes to the coil has power to it. There is no spark at the plugs. The EEC is new so it may not have any codes. I'll have to check the power to the DIS, but I am pretty sure that it has power. What grounds are there to check?

I'm sorry to see that you have had so much trouble getting the SHO to run. You are trying to solve a problem without knowing what the problem is. This costs time and money and doesn't necessarily solve the problem. An old saying goes, "85% of fixing something is finding out what is wrong."

Install the test jumper and run the key on engine off (KOEO) test by turning the ignition key to the ON position. The engine does not have to run to perform this tsst. This will cause the EEC to test the servos, sensors and motors that it controls to check for their proper operation. The error codes will be displayed. It may point directly at the culprit. See the site below for a very descriptive look at the EEC testing. Please.

I forgot how to pull the codes using the wire trick.

To run the tests it says the car has to be warmed up. Mine hasn't started in 3 weeks. Will the tests run OK with the engine cold?

Check out the link I posted above. No, the car doesn't have to be up to temperature to perform the KOEO test. Get those codes.
