Well I just finished putting the 1.8 ECU in the Tib, Thing is it wont run now. It turns over but wont start. I took the 2.0 out with the battery connected, did that do any thing? Should it be like this at first, then work right? Or did I mess something up bad? Thanks for the help!

I had my battery connected when I swapped it, and had no problems. As DTN said, definitely check all your fuses, then check one more time for all connections. Make sure you have the big plug on the ECU put in properly, it may not be seated just right.
And I have no idea how to check those big fuses either...

You check out the big fuses by looking at them and seeing if the little metal strap in them is melted.

lol RED I was talkin about the all black box ones. No worries though. I ripped my car apart lookin to fix it. I had no spark, I thought my alt. fuse was bad. I checked all the wires in the ecu harness to seee if 1 ripped. Checked all my other fuses. Finally put my 2.0 in. It fired right up. So I put the 1.8 back in and it started beautifully. Im thinking the main harness was loose up there. Thanks though guys!
