C8 Engine turns but will not start
Help - please - I have my C8 that was running absolutely fine and now will not start - the engine turns over but does not fire. I have had it transported to my local (trusted) garage and they cannot get their Snap-on computer to talk to the engine ECU - it will talk to all the other ECU's e.g. airbag etc. - it has been suggested by another garage that the 'Protection Relay' may be faulty but where is the protection relay located ? is this the Brown double size relay referred to in other (non C8) posts.
The other symptoms are - no fuel pump operation, no window operation
Any help would be appreciated.

Re: C8 Engine turns but will not start
I can't help but it may help if you can add some details such as what year, which engine and, possibly important, how many miles.

Re: C8 Engine turns but will not start
C8's don't have double relays as such, the injection/fuel pump relay is an integral part of the under bonnet fusebox. You need to confirm if the ECU has all its power supplies & earths.
Re: C8 Engine turns but will not start
Hi - sorry I should have provided the car details
2006 C8 Exclusive HDI 16v Automatic Diesel
113,564 miles
The relay I am trying to replace (once I have found it) is a 1920 7L - brown double relay - sold to me by my local Citroen dealer - it is listed on the Citroen Service website under Engine --> Air and Fuel Supply --> INJ CALCULATOR SENSOR --> item no 2
This is the relay
I am lead to believe that this is the Fuel Pump and ECU relay.
Thanks for any help you can give

Re: C8 Engine turns but will not start
I've got your PM - you didn't include an email address though. I have some documentation, but I can't send it on without an email (don't post your email here)geoffarm wrote:Is the relay I have shown not the correct one - it is listed on the Citroen parts list for the car VINwheeler wrote:C8's don't have double relays as such, the injection/fuel pump relay is an integral part of the under bonnet fusebox.

Re: C8 Engine turns but will not start
As i said in an earlier post the injection/fuel pump relay is an integral part of the under bonnet fusebox thats probably why you cant find it. Did the parts department search for this part from your VIN??geoffarm wrote:
