Hey just an update. Im not sure how I did it but I went ahead and cleaned up all grounds and the coil pack connections and then the car started up for me. Its getting late so I wasnt thinking about it to much when I said no spark yet backfiring. I been trying to get this thing started for about ten hours now. Anyways runs ok now except the big holes in the mufflers. Still not sure what caused that. Thanks to this forum I have found tons of valueable info that helped me through this thing. I still have the ABS and Traction thing to deal with but Ill start that another day. Anyways Thanks for all the help guys. This is the first Grand Prix i ever messed with and have learned alot in the last few days. I would have never known why I had Antifreeze in my cylinders if I hadnt read it on here. I would have thought head gaskets first. But like I said the upper intake was bad and definalty had a hole in it. Good info I found in one of the post on here made that job pretty easy.
