Something stupid??? I HOPE!!!

Maybe a little pricey, but there is also the mega-squirt. As I understand, it has been tested on the 90 and functional. I believe the later model was done first. Could be wrong.

Ok guys...just want some input here before I do the wrong thing again!



Found this online at a gm parts supplier. Looks to me to be the correct ecm I need, but I wanted some input from you guys if this is indeed the correct part number and ecm. So judging from this listing, the AC Delco part# is 218-12663. So here is the big question....I would imagine this would be the same ecm??



Or this??



Just want to make damn sure I order the right part this time!!! Thanks guys!!

The service # for the 91 ECM ends in 8331. Heck, just buy one from Haibeck,
Limey or Jerry. These other guys don't know what they're doing.

The saga continues!!! Got my ECM back from Solo Automotive Electronics in Miami today. Excited as hell to finally drive my beautiful garage anchor!! Threw it in and you guessed it!...Same problem! I am homicidal at this point! Called the company and they said they had replaced the injector driver and flowed the board. But I guess thats as far as they went. So the lesson learned for me is don't let them know what you diagnosed! Because thats all they fixed! I figured they would have at least trouble shot it! I should have just said it was broke! And let them find out the problem! Well the guy said send it back and he will find the problem...so we will see! I guess this Marine won't be driving his Z anytime soon!!! Can't explain how frustrated I am right now! Sorry...just had to vent!:-)

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!!!

Maybe break up your posts into a few paragraphs; this is really a difficult read.

But after reading the others' replies, it looks like you don't need your old ECM - that a new one from Marc, or Jerry, or Limey, like someone else posted, is the instant fix.

Isn't it?
