Hello. I have an issue. The car no starting. Has a P0621 code. I think ecu is damaged. no supply energy to ignition coil. nonetheless has a gas pressure. What do you think about it? The engine was running but we did disconect the battery and now Astra doesn't work.
maybe you forget some ground cable to battery then you was disconecting, also ecu must have ground. The fault p0261 is faulty injector, but i think problem is inside ecu , but car must start just 1 cylinder misfire

Misfires, not working cylinders. First changed ignition coils, plugs, after checked compression all was good. And last was engine control module
