start with the radio supression relay hooked to the radiator overflow, jiggle the wires while the engine is on and see if it stalls, next get a hose and stick in the gas tank and listen for the inner gas pump buzzing. You should already be able to hear the external pump when you turn your key. let us know what you find so we have a record of it. It seems alot of this is going on and we are jumping all over the map trying to fix it. thanks
