Hehe, funny youmention this, as I was telling Justin this exact same story with my car. Somehow it back fed one day and the pump began to stop priming through the ground signal from ECU. Did the exact same thing as you did to solve it, hence why I said check that ground side to the relay. Rocking that it worked.

Ive got an 89 coupe w sr20det w/fpr with no issues at all
the older cars circuits tend to have a lose of voltage under driving conditions

Agreed, and I have since done the same as well. This helps keep a solid battery voltage to the pump as well at all times, with the relay
(I simply ran wire from battery to a relay in the back, and then the relay to the power side of the pump. I used the factory 'power' from the fuel pump relay as the trigger, so it works just like stock)
