My gf called me one day and told me the camaro wouldnt run. The next day i went to go look at it and the first thing i did was hop in it and try to start it. It was completely dead. The only that happened was that the BCM was making a clicking noise. The only time the clicking noise stopped was when the key was turned over. It would also get lighter when i messed with the headlights switch. I then run jumper cables to the car and i would get her to crank and she would run about 2 seconds and then shut off even with the jumper cables still hooked up. I cranked her a few times and everytime i got the same results. The only time i got her to run a little longer was when i was reving the engine but right after let off the gas she would shut off. The day before there was a loud noise coming from the rear of the car and i was told it was the fuel pump. The day this happened the noise wasnt as loud as the day before but it was still there. Aslo when i messed with the headlight switch the intensity of the noise would change for a second. The theories ive been told are: the fuel pump could have gone out.... It could be the alternator..... it could be the crank shaft sensor..... or it could be an electical problem. She is my first car and i payed for her myself so i have got very attached to her and i really want to get her fixed. I hope you guys can point me in the right direction.
