1986 300 E fuel delivery problem
1986 300 E fuel delivery problem
No fuel to injectors. New fuel pump (aftermarket); fuel pump relay board good; over protection relay good; If I force the fuel pump relay on by shorting pins 30 to 87 the pump delivers fuel to the injectors. I see the fuel pump relay is relying on a RPM signal to close. What does this look like? Any ideas.
Thanks DES
