I even broke down and paid a website to contact a ford mechanic, and so far he's not been much help. In fact I'm beginning to suspect that he doesn't actually know much about this system or vehicle. His suggestion was to replace the entire pump assembly - his claim is that there exists a 'fuel pump transducer' as part of the assembly. I cannot find any trace of such a thing anywhere. The only sensor that Ford even mentions (this includes a very thorough search through various supply catalogues and troubleshooting guides) is the fuel pressure sensor on the fuel rail.At this point, the only piece of the fuel delivery system that I have not replaced is that damned sensor. Do they typically go bad without blowing the diaphragm, and if so, what are the signs of failure?</blockquote>
