Hi everyone I have a 206 cranks but no start
We have no communication with ecu
We have changed BSI key chip and transponder ,and ecu as well as double relay
We did have the car running occasionally with this set up
but it wasnt reliable .1 day it would start the next it wouldnt
Recently we did a chip test on the key it worked on the tester but when put into the ignition it was a no go .Remembering it was changed before.
So Im looking at possible problems with cables maybe going to BSI
Has anyone got a wiring diagram of a 2000 pug 206cc or any idea where to start
cheers Jeff

When it doesn't start are you doing the key beep test?

Found the problem It was a broken wire going from ecu to ignition and fuse box in engine .Wiring diagram was useless ended up using bosch system diagram .It was a 3 wire connection crimped with a alloy crimp that had perished
