[vasko]

hello members
i have serios problem with this car
i start car and 5-10 min run ok ...motor turn off....not have starter and not connect with ecu
after 5-10min start again ..all ground points ok power supply to ecu ok can ok
i learn 3 ecu's and same problem...
when car turn off throttle valve crazy and sound krkrkrkrkrkrkrkrkrkrrkr
sim module errors:u2100-00 can-bus high speed,u2105 can-bus with ecu.
abs errors
u2105 can with ecu,u2139 can with sim and u2100 can-bus high speed
ecu show multiple errors
p0201 injector 1 malfunction
p0202 injector 2 malfunction
p0203 injector 3 malfunction
p0204 injector 4 malfunction
p0230 fuel pump primary circuit low
p0650-ipc massage range
P1600-3A replace ecu
U2103 can bus no communication
crankshaft sensor ok ,camshaft sensor ok,throttle valve ok.
anyone can help with this F...k problem
Thanks

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%

I have before the same problem,and solved after replacing starter motor.

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.

[fra69]

but today i've a different case.
in ecu it's stored only p1600 intermittent.
and car sometimes turns off wile it's drived.
i don't want to replace more parts as last time,
someone have experience for this case?

I have the same case as vasko (https://www.digital-kaos.co.uk/forums/member.php/283183-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

Hello Vasko, did you resolved the problem and what was it?
