Hi folks, newbie and first post. Hoping for some advice and guidance as struggling to get to the bottom of this issue.
I bought a doblo 1.4 8v mpv with a burst gearbox and various other mechanical issues. As gearbox was to be changed and new sump fitted, thought may as well take engine out and do timing belt, water pump, change clutch etc and replace grinding steering rack.
The engine was running and starting fine before but after putting engine back in car the immobiliser light is on and engine turns over but no start.
I have checked the following...
All earth's resistance 0.5-6 ohms
Found broken pin on ecu, I must have damaged some how, got new cloned ecu.
Bought multieuscan and all that came up was u1601 on the body computer, Can bus error.
Interestingly no software info or any other information apart from iso number shown.Attached pic. Also unable to connect to engine ecu.
Battery is good and fully charged and cannot see any broken wires near ecu or body computer.
Cleaned all contacts with contact cleaner spray.
Removed radio as suggested on other threads.
Tried both keys, diagnostic says keys read but no code from ecu. Changed ignition key reader just in case, no difference.
Went back today to recheck earth's same reading with ignition off but with ignition on resistance jumps to 1.5 ohms. Could this mean a faulty sensor somewhere or issue with body computer.
Any suggestions appreciated.
Thanks in advance.
