Fuel pump

OK, here's yet another problem I've encountered. My car is giving me the trouble code 543, Fuel Pump Circuit is Open, Battery to PCM. WTH does that mean? My car is still running, so, what do I do?</P>

OK, I checked fuses, and the one link I could find. Don't know what else to do, they were all good. If I call a dealership will they tell me what needs to be done, or will they want me to come in?

there is a crk that runs off the same wire that your fuel pump get , it is after the relay , it branches off in parallel , since your car runs then some where between you fuel pump relay and your pcm there is wire broke , that same code i looked up may even be cause by a a shorteg hego and a faulty pcm , if your not too inclined with electrical work get a friend that does .
