Freaking out, I just bought a mint condition used 2000 DHS, only issueit had the erratic fuel gauge issue. So I disconnected the battery, removed the fuel pump assembly, fixed the sensor and reinstalled the unit to my dismay when the damn thing wouldn't start, it cranks, but won't start. I have had two mobile mechanics out to the house. Neither of which could figure out why. One said that it was to do with the security system shutting down power to the fuel pump but the telltale light is acting normal. It's not flashing rapidly or staying on. It goes off when the key is turning and stays off. All the fuses and relays are fine. Does anyone have any suggestions. I have tried the key in the door gimmick as well as turning the key to the on position for 3 tem min cycles but that didn't work and the security light wasn't on for any of it.
