You will need to remove the back seats and you will see the fuel pump in between the back seats and trunk. Run the car, remove the fuel pump fuse to relieve the pressure and then the car will die. Remove the pipes to the fuel pump, replace it and refit the pipes. Pump the gas pedal a few times and start it up (remember the fuse!)
If it is inside the tank (the fuel pump), then you will see the tank is held on by straps. Take them off, have ajack under it and remove the filler neck and screws holding it to the car. Remove the tank, undo the central bit where wires and pipes come out and slide the fuel pump out, replace what you have just done and refit.
Hope this helps, please vote :)

I had the exact same problem - the solution is to replace the main relay (or just run a soldering iron over it's contacts). I have a '91 Honda Civic Hatchback and it now runs beautifully after I retouched the solder on the circuit board of that relay.

The PGM Main relay is outboard of the glove box. You can see it if you get the glove box out of the way, but to remove it, you need to pop the triangular shaped plastic trim off of the end of the passenger side of your dash. The relay is held in place with one 10mm bolt and the electrical connector.

I think I would suspect the fuel injectors, especially since that is the code you are getting. Fuel injectors clog up, get dirty, stop working the way they should. They can be cleaned (you can remove them and send them to a company that cleans them and makes them like new, or, they can be cleaned in the car by some garages, or, you can get a can of Sea Foam spray and spray it into your throttle housing several times to try to do some cleaning that way, or, you can dump a can of Sea Foam (non-spray) into your gas tank and run it with the fuel through your injectors). You should probably check when you first start the car to see if you are getting any leakage from one or another injector (one or another may look moist or wet if the seals are leaking). You can also do the long screwdriver test (hold the bit of the screwdriver against each injector in turn and listen with your ear against the other end to see if each is clicking regularly). I would try the Sea Foam first.
I hope this is helpful in getting you started on a fix.
