Hi all
Could anybody tell me which end of the engine cylinder one is. I always thought it was the flywheel end on french engines. TIA

Disconnect an injector and see what the serial tool says.

Hi Keith
Thanks for the reply,tryed that last nite it wouldnt flag a fault up. I found that cylinder one is at the timing cover end by checking the injector calibrations.

Wouldn't flag a fault for open piezo injector fault, did you crank it (they will run on 3)

hi i thought it wasnt recommended to disconnect injectors due to them needing both open and close signal or am i being over cautious as the injector should be closed when ignition is off
why is it that the french decided to alter where number one is as i was always taught number 1 was at the free and of the engine would be nice if they all stuck to the same BASICS and component description

Hi all
Yes i did crank the engine but still didnt flag a fault up for open circuit for injector. Couldnt really run the engine as there was an engine breather that was off.

Martin
Do not disconnect with engine running.
Now think about the system and how it works, what is happening?

keith so when the engine is off and the ecu shut down the injector remains closed so as not to allow the fuel to bleed back therefore ok to unplug when off answered own question sorry been a long week
