Problem with my 2000 Pontiac Montana
3.4

tech = jk
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  

JK:
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.
