2007 g35 sedan sport . I was very methodical in tear down and reassembling after changing the spark plugs, denso's to autolite iridiums. Placed everything back and was extremely careful with the throttle bodies so that they wouldn't move. Checked all houses and electrical connection nothing was out of the ordinary. Went to turn the car on and just cranks . Btw before I even started I disconnected the negative battery cable . Any ideas why it wouldn't start?.

 

Did you

Ummmmm..


Reconnect the negative battery cable? 👀

Lol I kid but this is kinda odd that it won't start after a plug change. Did you ensure all sensors are reconnected?

 

Did you make sure to get the coil packs plugged into the correct harnesses, on some model G's you can accidently have a couple of them swapped.

 

Lol. Completely understand the irony it can be the simplest of things Lol Yes, it all went back together intact. The two front passenger spark plugs had oil in them one more than the other. I did change the o2 sensor as well . I'm going back in today and redo everything and check for spark and proper coil seating. The car was fine prior to doing this so, I can't for the world, believe that the fuel pump went bad or that I some how killed a coil or two or three. Might I need to do the relearn pedal dance?

 

It wouldn't affect starting. I'm betting you find the smoking gun when you're taking it apart again.

 

Did I hook the battery cable back up? Lol Well yeah duh! What I didn't do is push the electrical connectors back to the throttle bodies like a big boy. Haha
​​​​​​Gentlemen thank you for your time words can't describe how humble and red my face is out of embarrassment.
Thank you for your time and attention.
She struggled while some gas went in her but fired right up 650rpms and smooth.
Again, thank you much

 

Totally embarrassed, yes reconnected the battery, no, did not push the throttle body electrical connectors like a big boy. She fired right up

Thank you so much and forgive the knuckleheadedness. Ding on the man card

 

Lol no worries, just glad you got it all figured out.
