Darren/Mike Thanks for the replies.
Darren, sorry didn't make it to the SOM as I didn't leave work until gone 8pm ☹️
Your idea of disabling to ECU, which in turn will not power the fuel pump sounds good, not sure how easy that is.
Mike, Seven is 1.4SS with MEMS ECU, originally built as a racer. As for the wiring, must have pulled out loads of tape/poor connections/scotch loks, replaced where necessary with soldered joints and lots of heat shrink, good job there is a Maplins just around the corner from the office.
Cheers
Chris
