Re: NO fuel pump...
The relay is wrong IMHO. I had the same thing happen a long time ago, had a guy at autozone sell me a new relay and it wouldn't turn off, brought it back and he said it was the same part number for some other vehicle so he thought it would be the same cause they showed out of stock on mine. Went down the road to Advanced Auto and got the right one, worked great. You said you swapped in the SD computer and it worked, maybe he gave you a relay for a SD 88 mustang, see if they have a different relay for an 89-93 stang.
Not going to cancel out the computer though either. I can't beleive our cars are going to be 20 years old.....
Hey have you ran it at the track yet with the new motor?
