Unless you have a complete electrical problem, the only time the fan should come on at start up is if the AC is on.

Hello Olivier, I am curiously if you solved the problem with fans which start up after the engine start. I have the same problem and I have no idea what could be wrong.

Has anyone solved this as I'm thinking to believe it can be the relay switch as when I knocked my fan it shuts off

Hello Craig, I changed both fans, temperature sensors, from alternator I changed the diode bridge and the relay an I have the same problem. In my case the command for fans to run is received from injection (engine) ECU.
