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

How do you know if the fuel-pump is bad on a 88 Honda CRX?
To determine if the fuel pump is bad on a 1988 Honda CRX, listen for a humming sound from the fuel tank when the ignition is turned on (without starting the engine). If you don't hear this sound, it may indicate a failed pump. Additionally, check for fuel delivery by disconnecting the fuel line and turning the ignition on; if no fuel comes out, the pump may be faulty. Lastly, if the car cranks but does not start, it could also suggest a bad fuel pump.

The easiest way is to just turn the key to the run position and listen for a quick humming sound from the rear of the car. That sound it the pump running to pressurize the fuel system.
