2012 FIAT DOBLO 1.3 MULTIJET CARGO VAN 1000ono

Not running, i had a job starting it, so machinic swapped injectors from a 08 doblo . Started for a few weeks until one day it bllew out back smoke and stalled .. when I tried to restart it, it wouldn't start turnover but just wouldn't start .. I. brought it to a machinic, and they said it's the injectors that the other machinic fitted .. before this, I had codes p0100 p0180 p0110 all sensors I think it all related to ground wire. I had a clutch fitted and glow plugs that was when it wouldn't turn over only after several attempts.. i fitted a new starter and an alternator.. so anyone with knowledge of engines might be interested in fixing the cvrt test up in September
