fuel pump keeps switching off, ideas?

Looking at the board good chance the capacitor is a problem. Did you trace to see which pin on the ecu it connects too??
That way In the manual you can see what it controls.
Should not be too hard to get an ECU plenty being wrecked around the place. Only difference maybe manual or Auto ecu. Back then though there may not have been much of a difference like you get nowadays. Goodluck Vee

Just got back from the wrecker.
What i had was: aw319647

What i found was aw335189 (has new caps on it which was a plus, looks to have been re-manufactured)

Did some searching and it looks like the ECU i have been using is for a manual up to 10/94. The one i found was in an Auto of a similar manufacturer date to my car so i thought i would take the risk.
Interesting that someone has put a manual ECU in my Auto at some point before i got it.

Anyway, put the new one in no clicking so far. Started fine ran fine for 5 min or so. Haven't taken it for a drive yet but it looks to be fixed! Woohoo.
All up cost about $85 for the ecu and the dizzy cap. Not bad.

Lessons learnt
1: If you havent checked the caps in your ECU it probably would be a wise move. One of the others i found at the wrecker had leaking caps as well.
2: If you get really weird clicking off and on of various circuits, check the ECU caps.
3: Dont drop ECU circuit boards on concrete. :/

Just to let you know, all 4 cyl ECU can be interchanged in second gens which are 4cyl and all 6 cyl ones can be used in any 6cyl car. In short provided you have an ECU to match your motor you are good to go

Same with the TCU, provided you have the right amount of plugs (ie 2 or 3 plug) does not matter if oyu have a 4 or 6 cyl one
