Hello and welcome, since this is my first post on this forum!
I drowned my Niva couple of days ago and i can't start the engine
What's happening now? 1. Starter works for 2-3 seconds then stops 2. There's no spark
What broke? Immo, ecu or both? Or maybe something else? I've heard that when you try to start the engine couple of times with broken immo, computer gets locked and there's no way to unlock/repair it. Is it true?
Thank you

You didn't answered about @check engine lamp". Does it go on with ignition?
Immo lamp must go off after chip touch.
I did Glu - in point 2 ;) It goes on with the ignition. Is there some magic way to bypass the immo without disabling it in the computer? What should i do?
Thank you very much.

MrRav3N Yes, there is!))) You have to desactivate immo. To do this, you have to find "noimmo" ecu in your region, or desactivate it by repro. Activation immo is a flag in special part of ecu memory, called "flash". To desactivate, you must write clear flash dump.
I have no idea, how to help you. May be you can send your ecu to me by international trucks via your friends. Or send it to me by ems russia.

Your ecu is bosch 7.9.7. Only repro can dedactivate immo. If it 7.0 you could just resolder some chip inside ecu with 1euro price)

1. Fuel pomp finally works after turning the key into ignition 2. Starter doesn't stop until key is turned 3. Still no spark, engine doesn't start
4. My cheap diagnostic interface couldn't find the ecu with immo unplugged. After plugging the immo it worked (and works fine now, even with immo unplugged ) 5. Could information about the ecu be stored again in immo after point 4? 6. One fault code keeps returning to 'awaiting fault codes' - crankshaft position sensor. I've replaced it with a new one but nothing changed. Where are those two wires from it (green and white) going?
I don't want to buy a new ECU (not too cheap..) just to find out, that it wasn't the cause

The problem is here. If crank sensor doesn't work, motor will never start. You have to check wires from crank sensor to ecu. Green goes to pin69, white - to 15. (see red circles in attachment).
