So, i have some sort of issue with the battery being drained slowly. It takes about 6 days for the battery to fully drain, and its not the radio since i had it unplugged from the power. I try to boost it, the dash lights up fine, but the car won't even turn over. I do believe i hear something comming out of the fuel pump. The car started fine before the battery drained (a week ago). The car already has transmission problems (PMP switch) and potential fuel pump issues (once in a while it would take 10 minutes of cranking for it to start, but it would still crank). Any ideas on why the car wouldn't even turn over, not even a buzz out of the engine..?

 

Maybe battery is so bad it cannot crank the motor over.
Sometimes the battery shorts internally and no matter how much juice you give it the short will now allw it to crank.
