winterset Posted May 14, 2009 Report Share Posted May 14, 2009 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. Link to comment Share on other sites More sharing options...

Ditto, I have that same wire, and its cut off also, I just looked Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
Ranger Posted May 15, 2009 Report Share Posted May 15, 2009 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. Link to comment Share on other sites More sharing options...

In the world of conductors/semi-conductors/insultors, Nylon is an insulator!! Jim Drive your car. Use your cell phone. CHOOSE ONE ! Link to comment Share on other sites More sharing options...
Ranger Posted May 15, 2009 Report Share Posted May 15, 2009 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. Link to comment Share on other sites More sharing options...
Texas Jim Posted May 15, 2009 Report Share Posted May 15, 2009 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....

Ranger Posted May 15, 2009 Report Share Posted May 15, 2009 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. Link to comment Share on other sites More sharing options...
Logan Posted May 16, 2009 Report Share Posted May 16, 2009 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..
