Problem with my 2000 Pontiac Montana 3.4L.

Question = Why does my van not start when its
cold or damp or when it sits for 8 hours or more but
if i plug the van in with block heater it will start
when it does start it run a little on the rough side
until the engine warms up ,just wondering if it
could be the temperature
sensor  let me know what you think thank you  

Answer:
Hard starting when wet or damp outside is usually
caused by corroded ignition coil  towers and spark
plug wires. Just pull them off one at a time and
look for corrosion or  
rust on the coil tower and
inside the plug wire.  Plugged injectors are a
common  cause  for running rough. Also the fuel
pressure regulator leaking fuel into the vacuum line
will  cause a hard / no start and running rough, but
damp weather would not make a  difference.
