Re: 321 code in 740 wagon
Glenn, could you let me have a copy of the service correction, as my '91
Green book shows a cold start injector for Regina (B230F) in the wiring and
in component location diagrams. Amongst all my service and correction notes
I have no mention of this particular note.
JB, the relay you refer to is the Radio Suppression relay and sits by the
right hand strut tower. It is the common feed for all the injectors and is
switched from the fuel relay.
All the best, Peter.
