511 and 543 codes.. help
I am getting these 2 codes. I just installed a 347 in my '94 and when I start it up the check engine light flashes but doesnt stay on. From what I have been told, the first code has to do with the chip that I have plugged into the computer. The second one I dont know about. It has to do with the 'fuel pump secondary circuit failure'. Anyone know what would be causing this and how I can check it?
