01 3.0 Won't Start - DME Relay???

This explains the E Box Fuses:

From what I can tell, it was EF2 which controls the Injectors, VANOS Solenoids, CAM Sensors. This makes sense, as it was either EF2 or EF4, based on the location (2nd from the end of the little box) of the blown 30amp fuse in the fuse box, and EF4 controls the DME. My Fuel pump still worked, as I still had fuel pressure when turning the key, and if the DME fuse were blown, I would not have power to the DME Main Relay which controls the signal to the DME and to the fuel pumps.

Hopefully this helps someone else in the future.

From what I read, fuses get old, frail, and will sometimes fail with no other reason then the fuse itself.

What is weird, is one of the fault codes was bad DME Main Relay, but this just did not make sense as the Fuel Pump still worked....and the Fuel Pump will NOT work without the DME Relay working. I pulled the DME Relay to confirm.

Great find - you must be relieved!

And the actual fuse pack diagram. Follow the hotlinks for connectors (Xxxx) on bottom and you'll find what components are supplied by that fuse.
