Thanks for that.
Unfortunately, I know from hard experience parts swapping can be fraught
with dangers. In this case it was a necessary move. I use the shoebox
monitor, and the ECU with the pigtail for hookup was in the Carat, and I
SOLD the van - without the pigtail ECU, since I use it for trouble
shooting, primarily. I took the one from my 88 GL which was wotking fine,
and installed it in the Carat. Now the Carat won't start. Not even stutter.

It's always something!!!
