What I'm still not getting is how you can replace a fuel pump and still have it make the buzzing sound. The consensus in the archives seems to be that there are two causes for FP buzz syndrome: fuel starvation, either because of a clogged filter or because of a clogged fuel line before the filter, or bad pump bearings caused by the fuel starvation. How could "fuel starvation" make the same sound as a bad bearing? And how can you tell? |
