Hello all,
Same problem with my 03 6.0.
Fuel pressure regulator is good. After sitting, no pressure at Schrader valve, no gauge to check key-on pressure.
I have been qouted the following from Chevy dealer: p/n 19121626, Module, Fuel Tank Meter Sender/Connector, $545.88. Is this a separate part from the fuel pump?
Thanks,
Mark
