I have a 95 Ford Taurus OBD1. Check engine light code was 5-4-2 (fuel pump secondary circuit fault). Recently replaced the fuel pump and it ran fine for a couple days then I was unable to start it. I am wondering if I should replace the relay to see if the problem will disappear. Do I have to replace the whole Constant Control relay module or can I just replace the relay? Thanks.

Do you
have the same problem?

It's probably the module as the relay only works on startup also check for shorted wires rubbed through going from oil pressure switch to module
