The exact measurement of voltage from ECU to fuel pump relay 94 Hyundai Scoupe is unknown. Test it on your neighbour first. If he passes out upon contact, then it is good to go.
if you have checked the voltage with a dvom then you need to verify that the power source at the fuel pump relay is correct, if it has the correct voltage pre-relay then your problem is post-relay. if the voltage is not correct pre-relay then simply trace and repair the power source. if the problem is post relay then check the output voltage directly at the relay, if voltage is good trace and repair line from relay to pump. if voltage is not correct then replace the fuel pump relay
The fuel pump relay allows the pump to be turned on and off. On a 1995 Hyundai Elantra the fuel pump relay is located under the dash. There is a plastic module that is connected to the top of the ECM, on which you will find the fuel pump relay.
The Hyundai Elantra has the fuel pump relay under the dash on the drivers side. It is behind some wiring and is difficult to see.
Battery voltage
the fuel relay is ok,i cgecked it
No, the fuel pump relay engages and sends voltage to the fuel pump. The fuel pump requires 12 V DC to operate properly. A fuel pressure test will verify the condition of the fuel pump.
some models it is inside the gas tank. Some models it is mounted to the body right in front of the gas tank.
The fuel pumpis located in the fuel tank.
A fuel pump relay switch is an electric switch which activates the fuel pump when the engine is cranked and when the engine is running. The switch is located under the dashboard near the steering column on the 2001 Hyundai xg300.

12 volts.
The Relay is in a hard to reach place under the dash, along with the fuel pump relay and some others.
