2004 XC70 will not turn over/start

[UCrazyKid]

2004 XC70 Will not start. Battery is good, has fuel, will not attempt to turn over. I have tried to start many times and occasionally “immobilizer, see manual” comes up in the information window. Car in park, foot on brake.

Where to troubleshoot? I seem to recall the shifter position switch going bad and making the car think it is not in park causing this kind of issue. Anyone know the details of that?
Could it be a fuse?
The car does not get used much. Yesterday I went ti start it and battery was dead. Charged it for 2 hours and it started. I let it idle for I hour then drove it around a little. Parked it until today. Key turn lights everything up, battery has held charge. Just no turn of the starter.

Thoughts?
How would I check this with VIDA/ DICE (I have) for errors when no check engine light is illuminated? Thx.

I have tried unlocking the drivers door 3x to reset the immobilizer with no luck.

The battery needs to go on a 6 amp,charge rate charger, overnight , before you can proceed

Batteries are tricky things. They may turn on your dash and even headlights, but not have the power to crank the engine. Other times the engine will crank, but the electronics for fuel injection and other systems do not have enough voltage to work and the car will not start.
The battery must be fully charged to do any kind of starting test. As Absacate says, charge at least over night with at least a 6 ampere charger. Idle and drive around may not provide enough voltage to the alternator to actually increase battery charge. After charging, check the battery voltage at the terminals to see if it is near 12.6 volts with no loads. When you get the engine running, check the charging system to see if the battery terminal voltage is close to 14 volts. If less, your alternator/regulator or wiring is suspect.
