Trouble whit my engine

I'm having trouble coming my Tacoma (car A), to running.I bought a car that had been in a flood and everything was destroyed in his electrical.so I bought one that had been in a car accident (car B) and moved the electrical system from (carB) in to (car A). So now everything works. Except that the engine does not start. So I was wondering if anyone could tell me what would be best to start by viewing in the car so I will get it to running?

 

move engine from car B to car A and presto!! starty starty!!!

 

(Car A) 2005 model (Car B) 2006 model

 

Swap ecu or dealer for reprogramming.

 

Yes but Engine Control Module is new and transponder Key ECU also and key and remote is new also

 

Did you swap engines too or just electronics ?
If you just swapped electronics you need reflash ECU and programm all the Engine controls to the ECU. Its drive by wire so swapping ECu but not swapping every single sensor in the vehicle will not work. That includs transmission too.

 

Is this a math problem??? Car A / Car B?

 

I just swap electronics.

 

But I bought new transponder Key ECU

 

Did the engine run after being flooded?

 

I don´t know but that was no water in oil and I could not try to start because of the electrical break
