I’m having this issue where the wires plugging into the back of the fuel pump relay work their way out so I lose my fuel pump. I was able to fix it before by simply just putting them back in and holding them when I plugged the relay in. Now my cars stranded in a school parkinglot because they come out after the car runs for a bit. Not sure if it’s a replace the connections, new relay box, or just bypass it completely and put it on a toggle switch. Wondering if anyone else has had this issue and knows a fix

 

crimp the connector down a little so the female connecter is a little tight for the male......

 

When the female brass terminals push out the backside of the connector block, pull them free and you'll see there's a small tang right in the middle of the terminal that is designed to spring outward and lock the terminal in place, to keep it from pushing out. Just nudge it a bit with a small screwdriver or the like.

It would be a good idea, while they're out, to clean them off with some CRC LectraMotive electrical terminal cleaner and a toothbrush, and as noted maybe also tighten the part that grabs onto the male spade for a better connection.
