Scudo Fiat Scudo 2008 1.9 140 Multijet

Hello everyone hope some one can help
got problems with this scudo
plugged in my Texa diagnostic and getting multiple active faults
air tempsensor
fluxmetre signal
preheat relay
engine control unit
engine control unit start request
no coms with body computer
control unit activation

keep fiddling around and sometimes can clear the lot and all fine and dandy then drive it for a bit and then multiple faults
anybody got any ideas , I am thinking maybe a can fault or dodgy relay ?

Bad main earth cable..?

Try and check feedback from the sensors in that list..

Preheat isnt fussy.. but big current

Checked at the earths everything seems good 5v refrence at sensors and live data of map sensor seems to be working fine.
any body got a current wiring diagram, need to trace powerlacth relay (BSI)
and can line to check for a coms fault , bit lost without a wiring diagram help!
