The only way the engine will "Run-Away" is with extra fuel in the intake. What did you do to have the extra fuel-?? Clean the filter with gas-?

If the FASS filters are good-- check the fuel lines at the side of the trans--

The fuel filter message will show when there is a restriction in the fuel system-! [Plugged filters-- restricted lines-- sucking air] These conditions will also affect the power-! What did I misread--?? :rolleyes:

Pull the hose off where the filter used to be-- [engine off] turn on the FASS pump, turn the pump on and watch for flow-. should be a steady stream.

What is lift pump pressure set at? Does the LML do stupid things like the LLY with to much inlet pressure. Full fuse on lift pump to test this I guess. Where I would start.
