G35 won't start after wiring accident...Help!

[calvin12]

2005 G35 coupe...Before I start I want to admit my stupidity up front, however, if anyone can help i would appreciate it. I was running a speaker wire through the firewall boot on the drivers side of car. Had a knife through the boot, pulled the knife out and was going to put back through to make hole bigger, but when I was putting knife through I must of hit a wire and the engine began to crank. I immediately pulled knife out and engine stopped cranking. I then put key in ignition and tried to start car, everything works and engine turns over, but will not start. I suspect that the security system is preventing me from starting car, but cant figure out how to override...please help!

I think you just earned yourself a long weekend of suck.

You are going to have to pull the harness out of the firewall and autopsy the boot area. I don't know if it will be easier to disconnect something engine side or under the dash side, but mark connectors if you have to, tape over unused plugs, take pics, etc. Boots are usually injection molded onto the wiring cluster, so using a very sharp hobby knife or the like, slice from the outside in carefully and as clean as you can. after you find whatever it was you cut, solder and heat-shrink over it. You should be able to "glue" the boot back together with some RTV.

Grab some beers and some friends, you'll need 'em. Don't ask me how I know.

Might be worth disconnecting the battery for a short while then reconnecting.
