I was directed to here by Philip Andrew - he helped diagnose my broken fuel pump circuit on the ecu. The help was much appreciated as I'm still very much a beginner when it comes to car maintenance...
So I read this post
http://scimitarweb.co.uk/sgwrs/viewtopic.php?f=4&t=2013
Which was really useful - pulled my ecu apart and replaced the resistor. Then wired up a relay to power the fuel pump, controlled by the ecu's on/off fuel pump earth
However, it doesn't seem to be working - I'm guessing there is further damage to the ecu as it looks like the tracks have been very hot.

My question is, is there any harm having an ignition on controlled relay, to turn on the fuel pump... then it runs all the time (instead of toggling on and off like it used to when my ecu worked)? Will it overfuel? And if so would a good solution be an adjustable fuel pressure regulator?
Many thanks!
ps this is my car... bluebird turbo zx - few subtle mods (t25, huge fmic, piper cam, filter, etc etc)
