I've purchased a 00' 3.8l v6 camaro recently, and about three weeks after the purchase I've been experincing issues while trying to start my camaro or while i'm driving. Starting with the starting problems, upon turning the key, the vehicle will turn over for a second and then go right back off. Then, while I'll be driving it will start sputtering and then just shutdown the entire camaro. I'll lose power-steering and everything. The camaro also runs low RPMs while idling. I've thought it was the fuel pump, but i'm suspecting it's something much more serious now. If anyone has any ideas of what it could please feel free to help me out!
