clueless and sad

Hello to all
Back on January y shipped my 83 alfa from Huston TX to Cleveland Ohio
Upon arrival the weather was freezing cold. The guy who transported the car try to started and disaster strike. All the pulleys shatter to pieces destroying the water pump and the cooling fan
see pictures attached
I have expend close to a $500 in parts, replaced everything that was damaged (hard work!)
Today I turned the key to start the car and nothing happened, total silence
The only think that I noticed is that as I remember, when you turn the key one notch before going all the way to activate the starter, the ECU click. not happening anymore
Brand new battery
No blown fuses eider
Any guidance on tackling this issue? Maybe a link here of past postings with this issue?

I would remove and actually check all the fuses, sometimes itís hard to tell.

If the ECU doesnt click over then it sounds like an electrical issue..

Any chance the battery terminals were swapped? Negative for positive

Or a cable got loose during transport?

Is the battery fully charged? Not sure on the 83 but on a 91 below a certain voltage the ECU won't function.

its not the ecu that clicks but the two relays (fuel and main) near the ecu.

you say: "Today I turned the key to start the car and nothing happened, total silence"
If that is the case, it is another problem, as the car would crank over even with bad relays, and even if the cranking voltage was a bit low....it just wouldn't fire up.

(btw: yes, you need min 10.5-11.0V "cranking voltage" for the computor to awake on L-jetronic cars)

does everything else electrical otherwise work, like dash lights & gauges when you turn the key on (KO)? Indicators, headlights etc..all working as well?
If nothing works, your battery is disconnected

If dash lights work etc, but starter just does nothing check the thick red wires in the junction block (under the hood, drivers side on fender) or perhaps the trigger wire on the starter (spade connection) has fallen off, or your ignition switch has gone bad.

With headlights on, and then you 'try' crank the engine/starter, do headlights go dim?

I was thinking perhaps that the shattered fan pieces might have cut some important wire, but I can't think of anything up front to do with the starter, that it could be!

If the headlights do not dim when the key is turned to 'start' then no electrons are going to the starter motor. Could be a disconnected wire or a faulty key switch or a faulty starter motor.

And, L-jet is a system. All the parts have to work for it to work at all. See the link in my signature for a page of info about the L-jet system on our cars.

And, I've never heard of exploding pulleys - especially from attempting to start an engine! Got any more info about that?

could be his pulley shattered too....in one of those small photos (top right), I think I can make out a chunk of pulley missing...?

Maybe the crank position sensor got knocked off?

1983 has L-jetronic. Flywheel sensors (X2), not a crank pulley sensor like the '90 - '94 Motronic. But it'd be a good idea to to test the flywheel sensors (info in L-jet Diagnosis page). And even if they test OK with the ohm meter, remove them to check for physical damage (like a dent in the end of the sensor). Make sure they are re-connected correctly - the wire harness plugs are color coded (info in the L-jet Diagnosis page).

Another thing to check for are displaced contacts inside the plastic wire harness plugs. They can get moved out of position and then won't make electrical connection. The plastic plug may be plugged in but the contacts inside are not.
