Code 54, 1986


It turns out that both the fuel pump relay and the ECM were bad. After the fuel pump relay was replaced, it ran fine for about a week and then the trouble came back. I went through the troubleshooting procedure per the shop manual for the fault code and this time the relay was OK but the ECM was bad. I replaced it today and everything is fine. I hope it stays that way.
Have any of you had a similar experience? At any rate, I hope this helps some of you if you do.
