Default 350z Cranks But No Start

So last year while driving my 2003 350z died. I haven’t really had much time to look at it until now. When attempting to start the engine the radiator fans kick on high and no Check Engine Light come on in the dash. I’ve read a couple other forums hinting towards blown ECU. Was just curious if anyone has had the same issue and found a fix.
thanks!

If the fans are on as soon as you crank it, it's the ECM. It could be bad or it could just be a fuse. There are two ECM fuses.

Default Crank but almost turns over

Hi I bought an automatic nissan 350z shell and my plan was to manual swap it and get a engine for it so I installed the engine and the manual transmission and I completed the whole process of the manual and installed the manual harness and I installed a manual Ecu and reprogrammed the key to the bcm and Ecu and I did the wiring procedure with a safety clutch switch and the problem I’m having is that the car cranks and cranks and it almost want to turn on it releases combustion smoke from the test pipe and I used a obd2 scanner and my codes is p1122 so I need help if anyone ever had this p

Holy run on sentences, Batman! Why do young people refuse to use punctuation? Might want to start your own thread.
