I have a 2002 Grand Prix and mine does this sometimes and I have to wiggle my battery cables and it will start right up but it could also be caused by a bad ignition or fly wheel I had a 93 Grand Prix that did the same thing. Problem was caused by a tumbler in the ignition switch being out of alignment; that would not allow the starter to receive power.
No power to ignition switch check fusible links at terminals just to rear of battery. No power to ignition coil, check ignition module inside distributor, fuse, main power connector to rear of battery.
probably unsrew the old ignition and disconnect it from the cars battery then replace the new ignition and reconnect it to the car battery. you may or will need to take apart the dash board somehow. or you could just ask a mechanic.
make sure the car is in park. if it is then you might have a bad battery. charge the battery and get it checked. you might need a new one.
how do you change a battery on a 2002 Pontiac Montana
Seized engine? Dead or weak battery? Loose or corroded battery cables? Bad starter solenoid? Bad starter? Bad ignition switch? Bad neutral safety switch?
Check your ignition system/ plugs wires coil or coil packs.
Battery, kickstarter, ignition, ignition coil,
battery/ battery cable, altenator, ignition fuse, even not completely in park. otherwise solenoid, fuel filter fuel pump, relay. maybe a little bit more description would help though
For a Pontiac Montana the battery is a group 78. Follow this link for dimensions.http://www.rtpnet.org/teaa/bcigroup.html
A battery cannot be drained by a shorted diode when the ignition key is off.
The battery on a 2005 Pontiac Montana is changed by raising the hood, loosening both of the battery cables, and lifting them off the posts. The old battery can then be lifted out, a new battery put in, and the cables reattached.
