Thanks Mark - I appreciate the response. I figured e-mail would be a tough
way to go about this but was hoping for some suggestions like yours to at
least point me in some direction.

Yes this is indeed on the '90 but the wiring harness is from an '86 if that
matters (however all FI and wiring are the same as what was in there with
the original engine). When I looked closely at those relays they were indeed
exactly the same - I do not recall the numbers on them at the moment but
they were identical.

When the engine was out I did clean and remount the grounds you speak of -
maybe I didn't do as good a job as I thought - I will revisit that.
