Dead pathfinder 92 pathfinder died. got jump, it started but died whenever you cut off engine. Replaced battery, fine for a while then died again. got tune up, replaced wires, plugs and cap. Started fine for few days then died again. Got jump, started then died when turned off engine. Let sit a couple days, tried to jump would crank but not turn over and start.

NO CAR TOLD YEAR,MAKE OR MODEL NOR VIN#
BATTERY IS DEAD. WHY AND HOW WHO KNOWS?
WE CHARGE THEM USING A TOOL CALLED CHARGER

AND IF THAT FAILS TO MAKE OLD BATTERY CRANK ENGINE
THE BATTERY IS REPLACED. NOW.

EML IS CALLED CEL.SES AND MIL LAMP
IN ENGLISH IT IS CHECK ENGINE LAMP.
IT JUST STARTS SO THERE IS THE 1 KEY TEST DONE.
WHEN IT STARTS AGAIN
WE WHIP OUT THE OLD DMM,VOLT METER.
AND CHECK BATTERY LUGS FOR 13 TO 15VDC AT IDLE
BELOW 13VDC THE ALTERNATOR IS DEAD OR ITS FUSES BLOWN.

THERE ARE 6 CAUSES OF NO CRANKS.
FUSE] BLOWN
BATTERY DEAD (IT IS)
KEYSWITCH BAD (ST PIN)
PRNDL SWITCH BAD (AKA. PARK NEUTRAL SWITCH)
CRANK IN NEUTRAL NOW, DOES ENGINE START?
STARTER RELAY BAD
STARTER BAD.
OR ANY WIRE ABOVE CONNECTED.

OR BAD BATTERY CABLES OR LUGS LOOSE OR RUSTY.
THE BATTERY WILL BE DEAD IF ALTERNATOR FAILS
OR ITS BELT IS LOST OR SLIPS OR ALTERNATOR FUSES BLOWN
MOST CARS IF ALT FAILS AND WE DRIVE 30 MINUTES AND ENGINE DIES, FOR DEAD BATTERY./ NIGHT TIME LESS.
AT IDLE THE DAYS CHARGE/BATTERY LAMP MUST NOT GLOW.
IP CLUSTER LAMP

You have the battery and the alternator and the alternator belt and if they are working fine there must be something that is draining the battery. You need an auto electrician to check what the drain is. In such cases,on various vehicles, the BCM, body control module, proves to have something to do with it. Get A GOOD AUTO ELECTRICIAN to check if there is a particular component
draining the battery

These are indications of a dead battery. Have a load test done on the battery to check for a dead cell. check that the battery posts and terminals are shiny clean and tight.

Check the see what the voltage is at the battery with the engine running. You should see around 14 volts. If you see charging voltage than I would check the electrical system for draws. This needs to be done with a volt meter capable of reading amperage. If you have one and are familiar with how Ito use it I can explain the process.

first you half to determine if the alternater is working. you do his by jumping the car and while its running take of the neg cable off to the car if it dies then you know the alternater is not working properly,
if it stays running you know you have a electricalen short you half to trace down

replace the alternator,this is the problem,please rate thank you.

sounds like the battery has a dead cell in it. i would get a new battery.

Ignition control Module out again? Over energized?

this sounds like crankshaft position sensor, my Cherokee was ding same thing it ended up being crank shaft position sensor. this part costs about $50 and is easy to install.
