My 1988 honda civic dx will start when its cold and drive for about 10-15 minutes but then it will start to sputter as if it's run out of gas then it stalls. How do I know if it's the fuel pump relay? I know the relay board was replaced in July so i don't understand why this is occurring. Is the relay board and the fuel pump relay the same thing? Also I've read other peoples problems regarding bad fuel pump relays, and most of the time it states that there cars don't stall like mine but instead will not start after driving until about 30 minutes after the car's been shut off. My car will start if I let it cool down for about 30 minutes but if i try to start it right after it stalls the car just cranks without starting.
