Hello and welcome to JustAnswer!
If the battery is good but you have to jump start it even immediately after shutting the engine off then the problem has to be a connection issue between the battery and terminals. The only thing you're working around when jump starting is the battery and it's immediate connections. If there is no power making it from the battery to the cables then the issue has to be the battery or a poor connection.
The engine continues to run with the key off? How do you shut the engine off?
Customer: replied 1 year ago.
Engine continues to run happened 2x put key back in ignition gauges going crazy no accelerator. Put car in drive then reverse then key off it cut off. Charged battery all night then next morning attempt to start car turns over but no start as if no fuel. Upon battery dying jumped with another veh. Starts and drives fine but once shut off again no battery power lights dim, radio station loss and click click on key turn. Quick history vehicle came from MN. lots of rust under hood from snow and salt use on roads. Was wondering from form could it be the BCM? From water damage.

How was the battery ruled out?
Customer: replied 1 year ago.
Took to battery shop tested cells fluid then put a load on it at battery shop. Not auto zone or Pep boys. Wouldn't battery light also come on if battery was going or dead
Expert:  sprinkles08 replied 1 year ago.
The battery light comes on if the charging system isn't operating correctly.
How many cold cranking amps did the battery rest at?
Customer: replied 1 year ago.
Note also test alternator in vehicle with key off alternator was giving off amp as if vehicle was running. Battery dropped to 10v battery is a 650 cca. Battery charged initially for 3 hrs wouldn't pass 10v shop told me to let charge over night did that. Have not had it retested car starts off jump. Sound like your leaning towards a bad battery with bad/dead cell. With battery not taking and holding charge. Battery manufacturing date Jan/2014

What load was applied to the battery an for how long? Dropping to 10v with any normal test procedure proves a battery issue.

Gonna take it to shop now give me 30 min to reply, replying by phone. Would bad battery cause irratic guagues and lost of pedal/acceleration.
Expert:  sprinkles08 replied 1 year ago.
