@user_1931303 Oct 14, 2023MemberIntermittent starting issues have now become permanent, all since replacing the 7 year old original battery that died a month ago. Before making access to the starter motor I’m wanting to check the starter relay, is it ok to swap with the aux heater relay (same part no.) temporarily? Can this be done with the battery connected? Thanks.

Does it manage to turn the starter on at least for a while? Does it run erratically? Is there a knocking sound characteristic of this?Reply

It comes from the top right hand corner of the Inlet Manifold just below the metal bracket that supports the other vacuum pipes from the Rear of the Inlet Manifold. I have connected all of these vacuum pipes up but I just cannot remember or find another push on connection for the open end of this pipe. Please, Please can someone tell me where it is.
