Is there anything else besides air intrusion which will cause the ``start easy, run a few seconds, die and restart hard'' syndrome?
The reason I'm asking is that my '89 crewcab just occasionally has that problem. Sometimes it can sit for days and be fine, sometimes I shut it down for an hour or two and it happens. It consistently runs raggedly for a few minutes when it's cold - sort of an uneven idle, with an occasional, irregular miss. At -40 degrees, the funky idle is very noticeable. Once it warms up it smooths out. Still seems powerful, still starts OK.
I can't find any fuel seeps anywhere on the return lines.
It does have a check valve between the stock filter and the mechanical fuel pump, and it does have a Facet in line between the selector valve and the mechanical fuel pump.
The pump and injectors are probably in decent shape. I think it's a rebuild by Advance Diesel in Anchorage. They've been around a while and have a good reputation.
