So I've been getting a lot of help and now I'm at the point of getting my car started.
Background: 2004 g35 coupe, swapped out engine/trans/ecu from 2006 350z.

Got everything put in and everything connected and tried to start the car. It only cranks, I cannot hear my fuel pump and I had a walbro laying around so I tossed it in, still nothing. Check fuel pump fuse and relay. Swapped them out with others, still the same thing. Thought it might be the whole intelli-key thing and it does the same thing with the auto ecu as well.

Has anyone had these problems or similar experiences? Just trying to get lead in the right direction. I'm almost 100% certain all the plugs are connected but now this is happening maybe I missed something.

 

Very few people have done the conversion to date - so the help in this specific area will be limited. Wish i could offer more assistance but I haven't don't this conversion myself.

 

Thanks. I was thinking my Nats system was cutting out the fuel pump but I had a guy from the dealer look at it and he couldn't get his programmer to connect to my car for some reason to reprogram my key to the ECM.

Another thing is my fans turn on when the key is in the on position. Not sure why this is happenening it didn't happen before the swap. I was told it could be a bad control module??

 

Go in here and chat with this guy..he's doing awesome DIY's on this i'm sure he can help

I'd send him a pm. It appears he's done this a few times

 

Yeah I've been talking to him a lot, great guy very helpful. Unfortunately he wast sure of why it wasn't starting.

 

Ahh i see! Good luck with this, wish i could help

 

I have heard of the fans kicking on when ignition is turned to on position. If I remember correctly, it was a communication error with ECU to ignition. I think the guy had a bad ECU at the time.

 

You might want to swap the IPDM/er from the manual car donor to yours, If I remember correctly they are different from auto to manual.

 

Well it does it for either ecu I use, the auto or 6mt one. And I know for a fact the auto was good before hand...so unless somehow I fried both idk

 

I hope I don't need that because I don't have it

 

I'm in the midst of performing an auto to 6 speed conversion for my 06 G35. How do you figure the exact spots to drill for the and clutch master cylinder? Because there is no stamped imprint on the firewall to give you an idea of where to drill holes like the 240SX chassis has. Was wondering if creating a template from a car that already has the holes drilled for the and clutch pedal would work or is there a better method of figuring out precisely where to drill holes? I want to avoid drilling holes in the wrong places and have the line up against the break pedal at the wrong angle, or have the clutch pedal sit too low, too high or too far to the left or right of the break pedal.

 

 

 

Can't just swap in a new ECM, NATS/IVIS will trigger and you won't have fuel or spark.

The ECM, BCM, keys, need to be programmed together for the car to start.

You can do this yourself with NDS2 and a BCM decoder. Pretty sure you can Google search for a BCM decoder that's free.

 

Or tow to the dealership and pay them to program the ECM if you don't have the tools to do it.
