I had exactly thesame experience last two months ago with my rav 4 2004 model. This problem is common to rav 4 you can confirm it in on google. The solution is to buy a new brain box, further more you battery is already bad. I repeat stop doing trial and error, buy new brain box.

dudebuck:
no codes doesn't mean no problem, but you must use a high level scan tool check if all the signals ie the cam shaft position sensor signal, crank shaft position sensor signal, etc. But before then, for an engine to start it needs three things, spark fuel and air, you must find out the missing component to get a direction. If no fuel, then check the fuel pump and find out why it isn't running. If no spark is present, find out why the ECU is not powering the plugs.

Nairalanders please come to my help. My Toyota Rav 4 2007 model had alternator issue days ago, which required I take it for repair. When it was time to fix it back, the guy fixing it made a mistake in the wires connecting the alternator's socket . The battery charges again but would drain after parking it for some minutes. When I took it to an electrician (rewire) he complained about the spark on the battery saying it was too much. He tried checking the cause of the battery drain by checking all the fuses in the car with no solution. When it was getting to night time yesterday, he asked me to go with the car and return today. We managed start the car and on my way going back home, the car went off on the motion. I tried starting it; it cranked but not coming up till my battery drained off again. I looked for another electrician this morning to help look into the situation. The guy checked the plug, fuel supply and other things that might make it start. Later on he discovered that the CHECK ENGINE light, which should come up with other lights on the dashboard when the ignition is turned on does not show. He then concluded that the brain box is bad. According to him, if the check light engine does not show with other lights on the dashboard when the ignition is turned on, the car cannot start. He already removed the brain box but I am finding it difficult to believe it is the culprit.

Any one with an idea of what could be wrong with my car?

You can have expensive tools and diagnostic machines and still mess things up. Understanding how systems work from first principles is the most invaluable tool any technician can ever own. In fact a 5 dollar 'Chinese' scanner will give me the same result you are explaining here: It will simply not power up!

AutoElectNG:

Did you replace the immo?

The account does not make it clear, or was it a wiring problem between the immo and the ecm and the alternator.
