possibly a dumb question
Did you try bleeding the engine?

Unfortunately, I did not have time this afternoon to bleed the fuel
system but will do so tomorrow.
Another possible clue is that in the morning, it was very very hard to
start. I first thought this was due to the cold weather but I knew
that was wrong as it was turning over easily. I am puzzled at why it
would suddenly get air in the lines although it has been 3 weeks since
I ran it.
I vaguely recall something about the return line having something to do
with hard starting or stalling.
What does the return line do? Although it obviously would seem to
return unused fuel from the injectors, why is it needed?

The reason that I asked is this sounds very similar to a problem we had
last year where there was the tiniest air leak. It took forever to
diagnose and almost drove my poor husband over the edge. It finally
turned out to be the petcock on the fuel tank. (This after replacing all
the vacuum side fuel lines and the lift pump!)

Friends of ours had the identical symptoms, but theirs turned out to be
a clogged fuel tank vent line. (spiders) Again, it took forever to find.

That pretty much exhausts my engine diagnostic abilities. I sure hope
you find the problem. Please let us know what it turns out to be.

Cindy
