Hey guys so my g35 is not starting after I did and engine swap I have no idea why. I'm using the original harness and I can't for the life of me figuer this out, I swapped in a new ipdm and I swaped in a new ecm and still nothing, I go to the crank position and it just clicks I tried putting on my scan tool and all that communicats is the bcm everything is plugged in and all the fuses are testing good the battery has 12v and the starter cranks when I try to jump the signal wire, some help would be much appreciated

 

Need a ton of more info, but it won’t even engage the starter, etc?

 

no it's not engaging the starter what's so ever, ita a 2006 g35 and ive jumped the starter using the signal wire and it cranks but just turing the key normal wont even do anything not even a click, I do notice when I try to jump the ecu relay I can hear the fuel pump turn on but without jumping it it's not turning on

 

so I got an update on this turns out I did get 2 bad ecms the third time was ghe charm got 5 codes and atill a no crank no start

 

Code P1610 Nissan Tech Notes
This code is usually triggered when a not registered or damaged key is used to start the engine. When the starting operation is carried out five or more times consecutively with the same unregistered key, the system will lock. If the problem occurs try disconnecting the car battery for about 30 minutes and then try starting the engine with a known registered key. If the problem persists you have to have the dealer erase the code and reprogram the keys again.

If problem persists after disconnecting the car battery, try the following:

ESCAPE FROM LOCK MODE
1. Turn ignition switch OFF.
2. Turn ignition switch ON with registered key. (Do not start engine.) Wait 5 seconds.
3. Return the key to OFF position.
4. Repeat steps 2 and 3 twice (total of three cycles).
5. Start the engine.

 

The real question is with all of the ECM and BCM swapping did you pair the key?

 

thanks for this I will try it tomarrow amd keep you guys updated

 

haha I did not man believe it or not I thought I had f up my ipdm during the swap I was really thinking also that I've might have forgotten something to but I'll try programming a key tomarrow and I'll keep you guys updated

 

If you replaced JUST the ECM then it probably still won't work. The ECM and BCM are programmed together, you can either have Nissan Infiniti program them back together with the dealership Consult - II / III tool or you can do it yourself with Nissan Datascan, a laptop, and an interface cable. You can use an online BCM decoder if you want to do it yourself with NDS2.

The key RFID chip is then programmed to the BCM.
