It's our first winter together and my 1983.5 wbx 1.9 is acting up.  The
air temp was only -3 C on Sunday but she wouldn't start.  It would fire
occasionally but that was all. I plugged in the engine warmer and
recharged the battery. Now it was hard starting but did start only to
die after about 10 seconds. Did this a couple of times and I gave up
and took the Voyager.

Any idea where to start looking.

As always TIA
Cheers
Don
