Hi I'm new here although I have owned my ZX for 15 years. It's a 1996 1.4i 2 door and has been a great car until this recent problem. When I key on, the fuel pump relay is constantly clicking or chattering as someone called it. The fuel pump does not prime and the starter will not engage. Also the keypad immobiliser usually has either red or green lights depending on status, now it has both illuminated. I changed the fuel pump relay for a different one, said to be tested and fully working but it does the same. The battery is fully charged if that makes any difference. Has anyone got any ideas ?
