There are a few fuses that might have gotten burnt while you were working. Check the Fuse 7 on the fuse block. Also check the IGN SW 1 50a under the hood. Verify your wiring is correct and all contacts are clean and tight. Make sure your chassis grounds are good. If you dont find anything abvious, you are just going to have to start tracing back wires and find out where you are losing power. Hopefully it will be something simple, and you can find a quick fix.

Thanxs Mikey for the insight, I checked all the fuses on the inside of the car (box on passenger side dash) they check out okay. The ignition fuse I switched it out with a fuse right next to it which was the same I think it was for the cooling fan and still no go. Where do you think I should start tracing wires from or any other ideas. Wires are all bundled up and covered pretty good there whole length Looks pretty difficult. Thanks again.

Well, if I understood you in your original post, the car will turn over, but not start? Make sure you have a fully charged battery, and that all cables are clean, tight and free of corrosion. Dont forget to check the negative cable that attaches to the frame of the engine. Alot of times they will connect on a stud on, or around the starter. Make sure this is connected properly and getting a good ground.
It really sounds like a power distribution problem. If you have a meter, and know how to use it safley. Lol. Then check for power at your fuse block inside the car. Check for power at the number 26 fuse which is a 15a fuse that powers the dome, and mirror lights. I suspect that there will not be power there. If there is not, then it sounds like one of your fusible links or maxiFuse's might have gotten fried.
Here is what I see in the diagrams I have been able to pull up.
Battery power goes directly to the remote battery stud. Power for your headlights, horn, park lights, blower fan are tapped off this stud. Also tapped off this stud are 2 fusible links. These fusible links are inline of the generator and the starter. I see 3 MaxiFuses the are in the Engine Wiring Harness Junction Block 1 and they power different cells of the power distribution system. I would try and locate these maxifuses and check to see if they are good.
This is all assuming that you dont have power to your interior lights fuse, and if you do have power, then I would turn my thoughts to a ground distribution problem. In most cases, fuses and fusible links are plzced to protect the system from failure, so I am leaning towards that as being what is wrong.
Good luck, and let me know if you need some more information.

Mikey I cant tell you how much I appreciate you takin the time. Im gonna start asap. There was one thing I left out, before I jumped the starter in my first message, I was under the car while someone was turning the ignition to start the car and there was a spark coming from one of the posts on the starter I couldnt tell you now which one sorry everytime the ignition would turn it would spark, finally I jumped the starter, turned it off and this where I originally posted maybe this little bit of info helps. Thanks again

That makes me think you have a loose ground. Check all of the big cables that run from your battery to the engine block. Check from your altenator to the ground. You might have one loose causing all of your problems.
One thing to look for when u have had a sparking connector is damage. When u see spark, it is like a mini arc welder, and things can get damaged. I would remove all of your ground studs, clean them, and inspect for signs of arcing. I have seen terminals complely burned off from arcing. Replace any terminal you find bad, and make sure you resinstall all connectiong clean, dry and tight.
