So I have a 92 gt hatchback that I got from my father. I had to replace the fuel pump, the tank and the sending unit. Now I have an issue with the fuel pump relay on the tower constantly clicking on and off when the key is on. I replaced the relay, and checked the fuel pressure and the fuel pressure regulator and both are fine. Eventually the relay will hold and it will prime and fire but sometimes it will prime after 3 times and then other times it will continue to click on and off...
