SD> Fuel pump primes but no pressure

[swedeis@comcast.net]

Sounds like you either have a pump with a bad impeller (broken internally), a leak in a fuel line or a failed pressure regulator (won't hold pressure, will allow the fuel to circulate back into the tank).  

If you don't see/smell fuel leaking externally , its likely an internally failed fitting/line.

To check the pressure regulator, pinch off the return line, the pressure should spike fairly high.

Oh and Roy, check this out:  http://www.network54.com/Forum/12159/message/1207832830

Good luck,
Stefan
