if your pump is bad, you probably wont be able to hear it, as it will just stop. if you have your ear against the tank and have a buddy turn the key on, it should run for exactly two seconds and turn back off. if you hear it run but your car wont start, see if you can get your hands on a fuel pressure gauge (autozone or similar might lend you one) and check your fuel pressure. if it is a vortec, it needs at least!!! 55 lbs of pressure. otherwise if it has more than 30 it should at least run, even if poorly
