Thanks so much for all the input guys! Unfortunately, as I am moving into my new base housing this week, I am going to have to wait until the weekend to continue on. The car is at my parents place in vegas, and I'm getting ready to head back to Cali shortly. So hopefully this thread won't die, because I really value all the input from you all! And Pete, I almost stood at parade rest when I read your post! Lol. But yes...ready and willing to nail this!! I would love to my wife to the Marine Ball this year in a ZR1 chariot!! So here's is the newest update for today. On the line of WZR1's thought train, I spent half the night doing research on the ecm I got yesterday, and low and behold I do believe the ecm they have listed as for the Z, is actually for a LT1! Last 4 of the part number is 7727. As far as I can see the pn for my car should be 16163993. This probably explains why with the new one, all of sudden my fuel pumps no longer engage, but my cooling fan sure as hell does! Thats what I get for making the rookie mistake of buying a ecm through autozone!! I really should have known better!! But the good news is, they still have my core, and I will pick it up on the way home today! Hopefully this other unit didn't fry my prom! Pete, since I will have the ecm and prom for a week, and no car...I will give the ecm and prom a good thourough examination. And I guess we can proceed from there! Do you think I should go ahead and order the correct ecm...or do you think there is a chance this could a non ecm related issue? Either way, this is going to be a long week waiting to get under the hood! At least she will be on a trailer coming back with me next week! This week is sofas and furniture!!! UGH!!! Thanks again guys!!!
