Hey so on my 2003 g35 it was running well and then driving home from work it died . I checked the fuses, one was bad an ecu fuse and I found a coil pack was ugly like it was swollen and it gave off a misfire code for that cylinder (6). I replaced with new parts and the car cranks but won't start. I got all this replaced so far . Still no codes when scanned
new coils
New spark plugs
Fuel pump
Crankshaft
All fuses are working in every fuseboxx
my next hope is that maybe after replacing the cam sensors that will solve it
does anybody have any idea what else could it be ???

 

Any codes? Symptomatic of a bad set of cam or crank sensors.

 

No codes besides the beginning misfire in cylinder 6. And now that's gone. We changed the crank senssor but not the cams. No effect so far. New cam sensors coming in a few days so I'm hoping that might resolve it

 

Hope u are using OEM cam/crank sensors. Aftermarket sensors dont work with these cars.

 

This may sound silly, but how old is your battery?

 

All good now?

 

Crazy how I had the exact same issues I’m currently having, any solutions?

 

see above for cam/crank sensor replacement recommendation. It sounds like he had this issue and a bad coil pack.
