Pontiac Montana Hard To Start
2000 Pontiac Montana.
Question: i have a Montana that wont 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.
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.
Question: I have a 99 pontiac Montana that won't start. Brand
new starter. It turns over when done manually but not when using
the key. Have checked battery connection etc. No signal to
ignition from starter. Help!
If you're not getting power at the starter when the ignition is in the
'crank' position, that could be really only a couple different things.
You could have a bad ignition switch, although that is not really a
common problem on your type of van. You could have a security
problem which is more likely than an ignition switch. This could
be either a bad key or a faulty ignition cylinder. A quick scan of
trouble codes would tell you if you have a theft deterrent problem.
Otherwise, a wiring problem or bad computer could cause this.
You might also want to check the starter relay and/or fuse.

Question: My cruise control just stop working, it has worked fine
and then nothing, you move the switch and no light..nothing.
You're problem would need some in person diagnosing, as it could
be many different things that are causing the cruise control not to
work. First off, you should check the fuses and make sure that one
isn't blown, that's about the easiest first step I can suggest. If the
light doesn't come on, there is a possibility that the cruise switch is
shorted out, or there is a problem with the wiring to the switch.
Another thing that could be faulty is the actual cruise control unit
itself. It is called the cruise module and does the actuating of the
cable to the throttle to control the speed for the cruise control.
When the module goes bad, it causes no function to work. Usually
the switch will still work and the light will come on, but not always.
As you can see, there are quite a few possibilities here that can be
at fault. It would take some looking into by a qualified technician.
