2006 Pontiac Montana wont start after replacing battery. Engine cranks as soon a key is moved from off, then continue to crank even after removing the key.

To remove key (lock position), the transmission needs to be in PARK.

To start (engine crank), the transmission must be either in PARK or NEUTRAL.

Try apply parking break, put transmission in neutral and turn ignition key. If engine does not crank, turn and hold key in start position then move transmission selector to see if there is a transmission select position where it does crank.

Can be the battery old and need recharging. Or fuel not comes to engine - in this case call someone with tools and knowledge.

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.

Fuel filter,air filter,could be fuel pump,

i had the exact same problem in a 2000 pontiac montana, change the spark plugs and wires, it worked PERFECTLY for me. it went from being completely unable to start when hot/warm, to starting up immediately. its probably misfiring when its warm as was mine.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.
