Do you have fuel pressure at the rail? Isn't there a schrader valve you can push down to verify?

I know how to quickly access the fuel pumps on e30, e39, e36, e46, but never done one on e53. If the pump is just starting to fail (very common failure on BMW's) sometimes you can tap it with something and get it working again for awhile. Done that many times to get a car back home or something.
