    I had same problem with astra g

    Replaced everything

    In the end turned out that some fool put spark plugs without resistor causing ecu resets..........

    Replaced spark plugs problem solved

    Have had the same problem for 2 weeks Lift up engine ECU from engine ground, place on the rubber or paper(isolate) and connect lead from ECU ground to the battery ground, if car starts OK and throttle body keep quied, replace starter motor. 99%

    It is possible for starter to remain engaged and cause problems when car is running ?
    Same car ,same DTCs .After lot of reading on the web could be :-
    -coil
    -ground cables
    -faulty CIM
    On my case car stops while is put in 1st gear ,sometimes does not start in the morning but every time must wait at least 10 sec before cranking again .
    I am pretty sure that starter can give a lot of interference via supply lines which will lock the ECM ,but I have doubt that a bad starter will cause problems if the engine is already running .
    For a non starting issue this page offer a complete analysis

    REPLACE STARTER.....In my case Astra H z16xep easytronic....cranks 2 sec then fuel gauge goes down and engine check light disapear from cluster...OPCOM says NO COMMUNICATION WITH ECU...after clear all communication error try to crank...after to 2sec same issue...check every thing a hundred times....8 DAYS WORK ..at the last i installed a new STARTER...ENGINE STARTS ...REVS OK...NO COMM ERRORS....EVERYTHING OK.....
    I think that the old starter thru the positive 12v feed brings interference in ECUs...
    REPLACE THE CRAZY STARTER

    Mostly, spark coils solve the missfire and p1600 issues.

    hi i had a case on opel astra with mt35e ecu.
    i replace ignition coil, starter, ecu but i had problem again.
    sometimes car didn't start, starter run half second and after i've not comunication with ecu,fuel indicator goes down and trottle body goes crazy.
    after few minutes ( wait can goes in sleep mode, or removed ecu fused) i was going in comunication with ecu again and fuel indicators goes up.
    in this case i replace positive line from battery to fuse box, and car it hasn't been back from 2 years.

    I have the same case as vasko first post.
    Change ECU and add mass "-" to ecu from battery and engine start.

    edit:
    I had another such case later and replacing the ecu + ignition coil helped
