When you replaced the fuel pump relay, did you disconnect the battery and clear the codes? If you didn't, try that first and then take it out for a test drive. If you did disconnect the battery and it came back, try this.

Test your fuel pressure also. My Lo3 registered a code 54 when pressure dropped below fact. specs. Out put was 7 lbs. and was stalling and hard to start hot or cold. I installed a new pump, cleared the code and tested at 13 lbs. No more code 54!
