Hello all,
As a new Pantera owner I had my first longer drive with the car today. When I started the engine I noticed that it was not anymore running like yesterday. Below 2000 rev the engine seems to run to fat and when the engine is in idle it stops after a second. Full power seems okay. In addition, I found the fuel pump still turning even with the ignition key was removed and I had to remove the fuse to stop it working. Suprisingly, the engine also working without that fuel pump, which makes no sense to me. Do you have any advice?
Thanks and best regards

You have a wiring problem as you describe it, the fuel pump should not run when the key is off. The positive wire to what sounds like a aftermarket installed electric fuel pump is connected to a incorrect power source. Make sure ALL eclectically supplied items like headlights are off if you still hear the buzzing of the fuel pump with everything off, pull the fuse ( identify what the fuse is for, their is not a fuse for the fuel pump, as the car comes stock with a mechanical pump) , find the pump, follow/ trace the wiring from the pump, it should be wired directly to the battery with a relay actuated by a keyed power source. Could be a failed relay.
