Cold start problem

Post by Fox889 » Sat Sep 09, 2017 1:51 pm

I've searched the forum for 'cold start' problems & they all seem to have a rpm issue as well.....I haven't.
Only started last week, started from cold perfectly as normal, & immediately stalled, started again perfectly & no problem all day long.
Stop & started all day long [200 miles] & not a hint of a problem.
Stopped overnight at a B&B in Yorkshire, blow me, same thing..............starts on first turn of the key then immediately stops, start her again no problem & no problems throughout the day........weird?
The threads I have searched for, all have pulsating revs or fluctuating revs whereas mine is purely start-stop-start.

Is there a 'cold start' device that senses a drop in temperature perhaps?

All theories & suggestions very welcome indeed.

Ignition switch???. I have heard they can give all sorts of problems and are a cheap easy fix.

Must confess I hadn't thought of that one!
