Just to add to the database...:
After doing some work to the bumper on my 145, the car cut-out after I took it off the axel stands to move it. On trying to restart it, the engine turned but would not take, and the CODE LED remained lit.
I immediatly suspected that the fuel cut-off under the passenger seat had been knocked and triggered as I had moved the seat while the car was on the stands, so I pressed the reset button and tried to start her again. She turned, but no take-up.
I checked the fuses under the steering wheel, all OK, and pushed down on the relays to ensure a snug fit. No luck.
I checked this forum, and found a few references to this problem which suggested that I disconnect the battery for 5 mins and connect the two power leads together. This failed to fix it, and so did leaving it overnight disconnected.
Next morning, I decided that the relays in the 'black box of bo**ix" (Ref: RicksAlfas
wink ) May be the cause, so reseated all of them, but also noticed another bunch of fuses sitting there with the relays... then discovered that the Fuel Pump fuse was blown! Replaced this and after a slightly longer cranking session, she started up and began hunting as expected. (Hunting caused by the loss of the lookup tables in ECU, I understand).
So, I hope that this assists one or two AlfaOwners in the lifetime of their attention seeking Alfa Babies.
