Chevrolet Aveo mt80

Hello guys,

When i start first time, it is all ok.


When i then turn off ignition, but leave key in the ignition.
Car will not re - start. Engine will turn over, but no fuel pump sound from the gasoline tank.


Only after taking the key, from the ignition, over 10 second, will allow another start.


For some reason, i does not powerdown, the immo, and ecu, in the same session.
Atleast it appears that way.

Is this a common problem? In gm related cars.

I have seen similar issues after using wrong wires to hook up aftermarket car-radios and phone-carkits.

seach near ecu or immobox maybe there is an emulator soldered with wrong +12v and waits when main relay open contact to reset and lelearn to start the car again

Thank you, i looked for aftermarket tech, not emulators.

So i checked, No emulator, i needed to open the ecu. And nothing inthere either.

Immo diag responses. With emulator it would not. But i have not checked the immobox itself.
It wil be around the ignition lock. ( i will do a coil detection, and try starting without a transponder )


We dont know when this first accured. If it stays like this, they are going to leave it like this.
