Loose wire on a northstar...Where it's supposed to go?


Recommended Posts


I am the original owner of my '96 Deville. With the exception of the Fuel Rail recall, my car has never had any major work performed on it. I have the same wire, but mine was cut at the beginning. Only thing I can think of is that it was some kind of test wire from the factory? I know everything works on my car, I never did anything. Funny thing was I first noticed it a few months ago when I added a can of coolant into my AC for the first time.

That is the ground wire from the old nylon fuel rail. The stainless steel one obviously does not need one as it grounds through the mounts. It is quicker to just cut it than to remove it properly when doing the fuel rail recall.

Bravo! Thanks for solving that mystery

I have to challenge your response, Larry, and request technical details.

In the world of conductors/semi-conductors/insultors, Nylon is an insulator!!

I realize that Jim and can't explain that part, but I had the same wire cut on my '97 right after the fuel rail recall was done. Perhaps it has something to do with static electricity. I don't know, just shooting in the dark and I no longer have the '97 FSM.

I too was thinking of static buildup being the reason the ground wire (if that is what it is) was on there.

Couldn't the movement of the fuel thru the nylon create static buildup?

My background is not in that field, so I don't know the answer.

Thats why I am asking.... :D:D:D

I think it can. I've seen it happen by pouring fuel down a plastic funnel. Kaboom! It was a very interesting video to say the least.

From the GM TSB related to the fuel rail replacement.

"Remove the grounding harness bolt from the front of the right (rear) cylinder head."

And there is a picture too..
