can't jumpstart. battery problem?
My car will not start. The instrument panel lighting and messages all looked very faint. Electronics did not work. I couldn't even open the trunk. So I assumed that it was a dead battery. The battery is original (5yrs old).
I tried jump starting and all the electronics started to come to life very very gradually, but the car would not start. I let it charge while idling and even reving the donor vehicle for 4-5 mins. I then checked the electronics (sunroof, radio, windows) and it was working. As soon as I attempted to start the engine everything went faint to no electrical power.
I thought that if it was a dead battery, the car is supposed to start. Can anybody help me diagnose this problem?

did it get cold where you are?
the first good cold snap will kill a weak battery
pull the battery follwing the instructions so you dont ruin anything
get it tested if its bad buy a OEM one
OR if your in usa call roadside assist........ should be free but ask to be sure you would have to pay for the battery through
