Do the keys have to be coded to new ECU???
Yes, if the RAV has an immobilizer. No start with no codes. Check to make immobilizer recognizes key (security light goes out). Rarely ECU. Could be no fuel. Sometimes a shorted (intermittant) injector will do this... shuts down ECU immediately to protect it and so fast that no codes are even stored. Remove plug to each injector one at a time and see if it will sputter or try to start. Code should be set for each one disconnected. If not, there is some kind of electrical short causing ECU to shut down (de-power). Check for rodent chewing on wiring harness. There are many other possibilities and when you get one like this it can take hours of troubleshooting. That is why Toyota can't figure it out. Almost all dealer techs are trained to use their Techstream computer to tell them where the problem area is at but with no information from their computers, they are clueless. This RAV needs someone who can go beyond a dealership tech.

BTW, what year and engine?

So was this the first attempt after you replaced the engine, tranny, ECU and the other stuff you listed. Was the engine the same year as old engine. Could be a unconnected sensor or device.

A relay not turning on? :unsure: Fuel? Refurbed mass airflow? Maybe not a good idea.
Refurbed ecu cause the Toyota one is a over priced piece of trash I would never buy any other refurbed parts as a computer tech I know a board can be made better with good techs and also know Toyota has dropped majorly in quality last decade and will not own up to it so I will never pay 1500 for a brand new ECU

Shot in the dark, but on rare occasions, the starter will draw so much juice, the there is nothing left to tun the ignition or injection system. The ECU will not operate under a certain voltage. Could be as simple as an internally corroded red battery cable. Might be worth a try to put on a different cable. Then again . . . .

"that there is" and "run the ignition" My fingers have a mind of their own this morning.

No it doesn't I towed it home I installed Cam sensor

NO it still wont start no difference


tomorrow I am going to install fuel pressure regulator and new fuel pump filter

Then next I will do new coil pack and fuel injectors and fuel pump also new spark plugs .....spark plugs in now are only 1 year old air filters were still new


I discovered that the inside cabin air filter was ruined when I discovered rat nest remnants

Why not just change the fuel pump and filter while you are there. Did you check the battery?

Do you have a way to check fuel pressure at the fuel rail when cranking? Is there a fuel pump relay you could bypass to force power to the fuel pump? .... just a couple of suggestions there. Also, since you found a rodents nest, you might have a wire chewed into somewhere. I am assuming you checked the compression to be sure all your cam timing is proper. I have seen slipped timing belts or chains cause a lot of frustration, but generally there is a code stored in the ECU.

Yeah sadly I have zero codes I am gonna do the pressure check after if I can it doesn't really give me any way to check it no pressure release valve so when I get the fuel injectors off I will use a air compressor to blow through the tubes to make sure they are clean before I plug in the new injectors I had all timing checked at Toyota dealership bud sadly I can not trust those idiots to do anything so if vehicle does not start after I install new injectors I will take car to nashville to better mechanic for a $400 dollar diagnostic from a reputable place
