I have not read all the emails in this thread yet, I need to head off to work, but I want to add that I recently solved my intermittant no spark no voltage at the coil problem by tapping on the fuel pump relay. The mistake I made is I heard the fuel pump buzz and then checked it off the list as OK. Then I moved to the electrical issues under the hood such as coil, powerstage, suppression relay, rebuilding some of the harness connectors (which I still need to do the rubber is rotten and they get loose). I spent a lot of time measuring voltage and trying to figure out why some times I had 12v at the coil and sometimes I had nothing with the key on. I moved and touched nothing. What it appears to have been is the fuel pressure relay contacting with a mind of its own. Any way my new conclusions are that 1) relays can be the source of intermittant problems and 2) some times you need to go back to the beginning of your trouble shooting check list and start over again. I have spent money on coil and powerstage that I may not have needed, but they were 20 years old and if my teenagers are going to drive it I want to have these critical parts that affect reliability updated.
