[Vwdiesel] An off-topic, but Diesel question

Doesn't that one have an electric lift pump?  IIRC, in impending failure
mode, cold pump works, warm pump won't.

Sorry for the lack of VW content, but I don't know a better group of Diesel
mechanics.  Brother-in-law has a 92 Ford 250, about a quarter million on the
clock.  He finally got around to changing the glow plugs after a couple
years of ether starts.  Now it starts fine cold.  It, however, won't start
if he warms it up then lets it sit for an hour turned off.  I didn't know
what to tell him because if it starts cold, everything mechanical should be
working.  My only thought was that maybe the glow plug coolant temp sensor
was saying "don't glow" erroneously when it was a little warm, but not warm
enough to start unaided.  I know very little about those engines, though.

Thanks in advance,

-Shalyn
