No crank no start 2006 buick lucerne 4.6

[uhhhpooo]

Famous no crank no start, was running in my driveway one day then shut off, now doesn’t tell me what gear i am in and how much gas i have and fuel pump doesn’t turn on. Once in awhile fuel pump will turn on and go crank it and nothing then loses fuel pump. If it was a bad fuel pump would the effect the gear indicator on the dash?

Sounds like a voltage issue. Check your battery, just because it reads 12 volts doesn't mean it's good. Autozone and other parts places will test your battery for free. Also check you Alternator, a bad Alternator can cook a battery and cause electrical issues. They will also check for free your Alternator.
Bad fuel is not gonna affect your DIC/Cluster. However an electrical issue can mess with your ECU/TCU and sensors causing all type of ghost issues to come up. Don't throw parts at it, have them checked out first.

Hopefully its not your dash cluster, I had mine replaced and reprogrammed and its not cheap. I was having electrical issues from a bad Alternator that killed it.

Tried 2 different batteries, my alternator did go bad and I just replaced it

Well as long as the battery is a AGM with 850CC that should be fine. When it comes to a alternator get a good one. I spent $650 on a new (not a reman) one from NAPA.
Have you checked the ground points on the car make sure they are all there and tight? Something comes loose, rusted or breaks can cause electrical issues. I would also start to check fuses/relays. Under the rear seat next to the battery, under the hood on either side and under the dash. Hopefully you don't live in the salt or rust belt...

Checked a couple of ground points i checked all the fuses and relays, what’s confusing to me is it was running then shut off and started doing this

Can you test your fuel pressure in the engine bay? Should be a sharer valve. the PSI needs to be between 55-60 PSI.

Also dumb question, if everything is working and it starts and turns off right away it might be the anti-theift system. The chip in your key can just go bad and the car wont start. In that case you need a good key or someone with a scan tool that gives access to clone keys/fobs. If you have a good key to use....

To reprogram a key fob on a 2006 Buick Lucerne, use the Driver Information Center (DIC) by turning the key to the ON position, locating "RELEARN REMOTE KEY", and pressing the Set/Reset button. Hold the Lock and Unlock buttons on the fob for 15 seconds until the car chimes.

Fuel pump doesn’t turn on at all, so can’t test that, security light doesn’t pop up on the dash or anything.
