Hey guys. I have a 1994 ATX with 52k miles. I drove to San Diego from AZ last week and my CEL popped on for about five minutes just as I was getting into San Diego. It then turned off for the remainder of the trip and the car ran perfect back to AZ averaging 26mpg. I decided to pull the codes once I got home to be on the safe side. I got 176, 177, 212, and 543. Do these all point to the fuel pump going out? Thank you.
