Hi, im currently looking to do a compression test to see if I have a blown ed gasket. From what I read, I need to disconnect the ignition system prior to running the compression test to disable the sparks produced.

Anyone know how to do this on a 2003 Frontier XE V6?

Assumption: You have a distributor (my 2001 has a distributor).

Does the compression check that you are going to do require removing all spark plugs?
If so, I would just pull all the plug wires from the plugs.

Otherwise, perhaps unplug the wires at the distributor cap.
Or remove the inputs to the distributor (there is no external coil on my setup).
Without input voltage to the distributor, there should be no sparks thrown.

I hope this helps, let me know if I led you astray on this.

Ok, so I managed to do the compression test and everything checks out (with the exception of #6). However, I'm having a hell of a time getting the #6 plug back in. I don't see it and my hand doesn't fit back there to do anything. Any tips on getting this one in?

I have replace the #6 spark plug on a 3.3. All I remember is that it was a challenge. It would probably be easy for an experience mechanic, but for me, it was a challenge.

It was all by feel, plus a combination of extensions and knuckle joints.
Be careful, I think the heads are aluminum.
I think there is a write up with hints on this in the 1st gen forum. Youtube may have some tips, I think the 3.3 engine was common enough for there to be youtube videos.

If you live down the street from me, I would give you a hand.
