[928uk] No start!

[Paul]

There is a much worse failure mode

Rough running one day, then seems fine for another 500 miles

Then the car stops completely, and has to be towed to a local garage

When the French garage then checks the car the following day, it starts and
runs fine

So I try again and the car runs for another half day before cutting out,
and I gave up

The car was then recovered to a garage in the UK that the PO had last used
to service the car, and they diagnosed LH failure

I managed to buy a used LH for a few hundred quid, and that then ran fine
for the next twenty years, 90,000 miles

Then it failed, thankfully when the car was at home, on the morning of the
Merry Miller meet a couple of years ago

JDSPorsche either didn't exist or had only just been setup in the summer of
2002, otherwise I wouldn't have fitted a used LH

It is so much more relaxing knowing I have one of Michael's rebuilt LH in
the car now
