Re: [DML] Re: She starts (painfully), she runs (mostly), she doesn't go anywhere...



Look at the Bosch filter inlet. If you see a black plastic piece just past the threaded portion, don't use it. The threaded portion of the inlet line can bottom out against it restricting flow and causing fuel starvation. I don't know if John is selling old stock or new for the filter. 
The low voltage ends up requiring more amperage to run the pump. This will eventually burn out the pump. There have been several threads on this issue. My particular voltage loss was mostly due to the crimped eyes on the wiring harness that connect to the fuel pump. Years of messing with the harness had loosened up the crimping. I got a new piece of harness and soldered the lugs. Check your inertia switch too. Make sure the ground is good as that is what the pump is grounded through. Does your fuel pump make a lot of noise after the car is warm?  The high amperage may have damaged it if this has gone on for awhile.  Not sure about your modified wiring. I've only ever had 2 wires running to the pump. 
If you are running the original pick up hose in the tank from the pickup to the pump then you should replace it. They tend to collapse, starving the pump, when the fuel gets warm. I was on the road when this happened and stuffed a spring down it to keep it from collapsing till I got a new hose.
