I can help you but only if you want me to help you
All the questions should start from what car, what year, what engine is what fuel. What are the symptoms of the problem. Only then is what you know, what fault code, live data, what you have done.
DTC :U1101
ALLWAYS IN ENGINE ECU
Most cars can start up without their A/T ECUs....have you checked fuses? If there's no communication between ECUs that might be because there's no power supply...at least that's the first thing I'd check if I were you.
BTW.: might be a stupid question but is the engine cranking at all?
Hi friends
Yes the engine turns ordinary but, have lack combustion. I will take all suggestions into account and recheck all components suggested.

Hi friends
Today checked all connections, fuses, relays, feeding system are ok, but When checking the sign of injectors found "759 to 845mv" no have the sign for injectors.
I called the diagnosis "autcom" came:
U1190 - No reception failure detection signal
U1101-T / M, while the CAN exhausted / not fitted
I cleared the errors and left:
U1190 - No signal reception failure detection "
Somene can help me to have electric scheme for verification.
Thank in advance

Hi friends
Solved the was right, even with the error "U1101" the engine starts without problems but the issue is that the electro-injectors were arrested. After 3 attempts to smell gasoline only then started the engine after the start of the electro-ijectores the car now starts normally.
DTC :U1190-came because of 2 fixed the fuse box were poorly fitted after correcting the error disappeared.
Also noticed these electro-injectors work with lower voltages "789mv to 2 vol " saved error.
I would like to thank the collaboration of all
Thankss

Hi ive got the exact same problem now, can you explain what you mean by the injectors were arrested, how exactly did you fix the fault. im on the verge of removing the injection pump to carry out internal inspection.
My engine cranks just as you have described but no hi pressure fuel going to injectors.
