Technical Engine stopped fiat 500
Didn't sound like it would work as the engine wouldn't have cranked if the earth was that poor? but was worth a try as it's so simple to do.
You cannot IMO replace the orignal earth straps, as the original earth goes from battery to chassis, then chassis to engine. Whilst you have provided a good earth to the engine, you haven't supplied a good earth to chassis, which many ECUs depend on.
There is a separate earth lead from battery to chassis which was ok
Ah, ok. Did you clean up the connections?

Yes, this us how:
But as mentioned before, is easier to check if the sensor is working by watching the RPM gauge while cranking the engine. If the needle moves up, to like 200 or so, the sensor is ok.
Do you know for sure there's no spark or is that just a guess? Is the fuel pump working? Do you hear it humming when you turn the key on?
Does any light remain on on the dashboard, like IMMO?
i did a multimeter earth test fine
No good. The small current from a multimeter will pass through, and give a satisfactory result, but a full load current still won't pass without an horrendous voltage drop.
Its to see if connection is clean, continuity

Still no good for high current paths.
You're passing a few mA's using a DMM, a single strand of copper would pass that current, and give you that reading, but it wouldn't turn your starter motor.

This is the test you should do.
For the ground cable, it's the one from min 2:00 in the video. If the battery negative to the block is under 0.2V while cranking, the ground cable is fine. Use the multimeter instead of lamp tester.
Don't know the price of a cranksensor, but I would be tempted to replace it with a good brand.

Are you saying it is crankshaft sensor?
