car won't even click over
I put the key in and the lights started flickering and then i heard the fuel pump start and thats all the power is very little if any. I took the alternator out and got it bench tested and it was perfect or so Vatozone said, then i replaced the clamp on the black wire or the alternator and it wasn't that. Well i decided to jump the car and then it started but as soon as i took the jumpers off the car sputtered then died. i dont know what to do but its now been in the garage for a week, and any help would be appreciated.
