I finally got it back together and it started the first time. The idle is a little rough, but is beginning to smooth out. I do Have one problem, the fan on the rad with not go on. I do not have a decoder, but put a test light on the wring and there is no juice. ALso at times it stalls out adn the vacum is low, then it picks up again, seems to idle better in Drive. My main concern is not having a reading at the fan motor...Any ideas, I replaced just about every sendor when I redid the engine.
Thanks
 
Unplug the ECT sensor......

Your fan should come on and you will get a CEL.....

If this is the case, you need to replace your IRCM....

These are the only ones I have seen on 89 and 90 SCs.....
