Year? Miles? Engine? Sounds like a bad fuel pump...when you turn the key to the "run" position not start do you hear the pump come on?...should be a humming sound that comes from the rear and it should last 2-4 seconds...

2010 Rav4 4cylinders, 80 000 km. This problem happens since I maded a big engine job. Monday I pulled the engine out of the car for a oïl pan problem. Before, I did not have this problem. I dont hear the pump.

All I can suggest is double-checking all wires and hoses to makes sure they got reconnected.

Does the RAV monitor oil pressure and cut off fuel if oil pressure is lost? If so, and the wire to the oil pressure sensor is not connected, the fuel pump will only run for that couple seconds of starting.
