Hi. Update on my 500 SL 107 fuel problem. I bypassed the fuel relay and ran live so pump is on all the time. Open all pipe connections at injectors and then opened air intake. Fuel was coming out of all injector connections. Put fuel relay back, turned the ignition on and pump worked as it should for a few seconds, cranked engine over no fuel at injectors.
One thing I have noticed on the fuel accumulator. I can blow through it one way but not the other. Is this correct? Any ideas please
