Pontiac Montana 2006 won't start just clicks but

Sounds like a bad starter solenoid, or starter. Change the starter solenoid.If bad no click to energize starter. Good-Day!

Sounds like you found the problem . get a new MAP sensor or take the one you have to the dealer to be tested . Good Luck

Sounds like the anti-theft/alarm system was triggered.
Have you tried locking and unlocking the driver door with the key to disable the alarm ?
And you need at least 12 volts to crank the engine so the battery may need to be charged up first.

I have to ask, did you connect or attempt to connect the cables the wrong way round! Sounds like a main fuse has blown, some vehicles have a fusible link directly connected to the battery, you may have disturbed or broken a wire off the battery when you connected the boost leads. This seams like the only explanation. Good luck

could have a theft deterrent problems.

just had the same problem and i ended up having to change the altenator, for 2 or 3 weeks i would have to bang on the altenator with a hammer while it was running because my battery light would keep coming on. but after a few taps with a hammer you could actually here it start working again. i did that one to many times and broke the housing on the altenator and eventually had to replace it.

First thing I would check would be the battery. Open the hood and make sure the battery terminals are tightly connected to the battery (try to turn them on the post by hand). If they are tight and you have a volt-ohm-meter you can check the battery charge yourself. If not you can remove the battery and take it to an autoparts store and ask them to check it for you.

2006 Montana, I am trying to remove the kick panel on the passenger side of the dash. I want to rivit a piece of aluninum to it because the valcove tape won't stick to plastic.

If the car was running when this happened and now it won't start, I would have to take a look at the starter to see if it got wet and make sure it is not shorted out. Also the wiring from the battery to the starter may be wet and shorting as well as something in the fuse box. IF it is clicking then I suspect you have some power to the starter but not enough to turn it over. If you ran the car for a while after it was wet you could have damaged the altenator and it may not be charging the battery and the battery may be drawn down to where you don't have enough amps to start the car. Try jump starting to see if it is related to the battery if not then start looking for electrical shorts in the wiring to the starter.

van wont start, batterys chrged, turn key nothing, does that mean its the feul pump?
