Only thing I can think of is contamination in the fuel system?

I just put a rebuilt 1.9l NA engine into a customer's Vanagon to replace
one that grenaded on him in under 5k miles (don't ask).  The new rebuilt
one is from Parts Place up in Michigan but it is actually rebuilt by the
guy that does vwdieselparts.com.

Anyway, the problems that the customer is having since installing the
new motor is that when it starts up in the morning it seems to spin over
a bit more than the previous engine.  Also when it starts it smokes a
bunch and runs rough for a short time until it warms up.  Once it is hot
it actually is harder to start than it is when it is cold and cranks
over even more.  None of these problem existed with the previous engine
which would start up at the touch of the key once the glow plug light
went out and didn't have any hot restart issues.  All of the fuel
injection and glow plug parts were just swapped over from the old engine
and I set the timing the same way I did on the previous engine with per
the Bentley Manual for the 1.6l NA engine.  Can anyone give me an idea
of what could be causing these issues?  The fuel pump is a rebuilt unit
from Parts Place and probably only has around 10k miles on it since
rebuild.  Any thoughts would be appreciated.
