Technical Now not starting

[Fiatinaus]

Hi Brainstrust
In Australia with a fiat 500 twinair dualogic(selespeed) which had problem with gears after removing gearbox noticed the thrust bearing was destroyed was running fine before it tore down

Replacement clutch installed and now it will crank but will not run (like its misfiring and when it does run its really rough)
Robot was removed from box before removal but put on I assume correctly on reinstall
Have double checked all plugs earths etc
Can't seem to work it out
Please help
Thanks in advance

There may be hidden damage to the earth cable on the gearbox.

Put a single jump lead from the battery negative to the gearbox and then try to start the car.

Did you drop the engine oil for this repair ?

Just a couple of recent threads on twinairs:

Yet another TwinAir misfire right after an oil change. | FIAT Punto (2012+)

Punto TA just under 108K miles. Already had new clutch and DMF this year Grrr!! So I changed the oil & filter a couple of weeks ago, air filter and so on. Used the correct grade of oil (5W40 C3) same Napa oil brand & grade as had been in since the previous change. I’ve cleaned the oil...

Twin Air oil change, what's wrong? | FIAT Panda (2012+)

I'm doing the second oil change in our Panda Twin Air. With the filter canister and filter removed, there's about half a cup of old dirty oli in the base of the filter housing. Is this normal? Am I supposed to drain it away somehow? It seems a shame to contaminate clean oil with this much...

will check that thanks
The earth is attached to the duelogic selespeed robot and my some used silicone between the robot and gearbox maybe that could be breaking the earth

Did not drop engine oil
only gearbox

Silicone is an insulator, so fingers crossed its sorted now?

The factory earth cable can rot internally,

Try adding a jumper cable..
battery Negative to gearbox

Thanks all
Now starts but didn't think a low battery would cause these issues
