Do you get a key symbol on the dash? If so the immobiliser doesent like the key/there's is a problem with the key/sensor.

no key light on dash,it started ran for about 30 seconds then switched off as if ignition was switched off,only codes are 6.3 crank sensor and 7.2 immob?

Hi

Serial data would be much more helpful than blink codes which can be misleading on Iveco

Failing that for starters, measure the rail pressure at the sensor when cranking with a DVM, should be 0.5 v key on not cranking and rise to 1.2v min when cranking. I think from Emory it is the middle terminal, but easy to work out as other terminals should be 5v fixed and leas than 0.2v

It would be a good indicator but ECU will have more than one power feed so suppose it is possible that it would only be partly powered, clearly if no voltage you deffo have an issue.

That said you say you are getting blink codes so presumably it has power

Hi

I guess that's a Delphi clone ?

Bit surprised there is no one in the Northampton area that can deal competently with an Iveco

Take the pipe off the back of the injector pump (not the one that goes to the engine ecu). Crank the engine over and you should get fuel pissing out the pump. If that is ok connect the pipe back up and unplug the regulator. Try and start again. If it does it will rattle and knock. When you try and start does it smoke?

Whereabouts in Northamptonshire are you?
