Service Engine light and Code 54

[Jmu1]

Hello all, need some guidance. I have a 1995 ZR-1with almost 28K miles on it that stranded me. I got it back up and running with a new battery however it is giving a Service Engine light and code 54. As i understand that indicates low voltage on the fuel circuit. So I have replaced battery and both fuel pump relays. I had also replaced both fuel pumps back in September of 2020 so they only have around 200 miles on them. The light and code re-appear after being cleared. Any ideas where or what i should look at next? Thank you for your help.

Any opinions on this? It?s been almost a year and didn?t receive any replies. I?d really like to get this issue solved. Thank you for your time.

Several things can cause that code. One of the more simpler ones is a bad fuel pump relay. Cheap and easy to change if you want to just try that first.

Follow factory service manual diagnostic tree for code 54 is my best advice.
