View Full Version : 95 FWB RWD Engines dies

12-04-09, 04:55 PM
I have a 95 with about 125K miles. Has always been a trouble free car. About a year ago the engine shut off without warning. Since the car was low on fuel anyway I topped it off and it started fine. About a month later dies again and my local Cadillac dealer suggested replacing the fuel pump.
Once fuel pump was replaced caddy ran fine for about a year and then died again without any warning. About $200 in diagnostics later, ended up replacing just the relay for fuel pump.

Ever since then the car would die seemingly randomly and would start back again most of the times. This last time it didn't and I had to tow it to the mechanic. Once there it started up right away.

So far,
We checked fuel pressure, fuel pump, filter, relay, fuse etc and everything is still fine.

Does anybody have any ideas? I love my caddy but it has already left me stranded 6 times :helpless:

OK, got this one nailed!!!!

the problem is not the fuel pump
but the harness that connects from the top of the f/sender
to the base of the pump, the wires are known to melt
its a common issue, even on a bunch of chryslers
, even if the wires appear fine the contacts turn black
with some kind of a deposit, and the connections breaks down

usually it will be fine, for a while, then die out, let it sit for anywhere from
5 min to an hour and it starts right up, runs fine
I have a part # for a better harness made by carter corp
it wont melt! and the connections are better
however, you must clean the black deposit off the f/sender 4 contacts
I use a finger nail file, the ones all chicks seem to have
and its as simple as cleaning the blades(that the plug attaches too) off before putting the new harness in
all can be done at home if your m/incline, not difficult
or if your anywhere near me I could do it for you and keep the cost down
if you bring it to a dealer or garage, they will want to replace the whole sender, dont do it!!, its like $400,and you dont need it

I have fixed and know of this issue on at least 7 other fleetwoods broughams
in the past 3 years..............Jim

@ the fleetwood guy
This sounds promising. I also looked at your website, good stuff.
I live in Madison, WI, so I am too far to bring it to you, but could you share the part number.
Thanks so much.

sure CARTER #888536 in tank harness
(division of federal mogul)

make sure you have them clean the terminal spades (4) off
with light sand paper or as I mentioned first post
that is imperative , I have NO doubt this is your problem

So I finally got my car fixed, Yay!!
Kudos to the Fleetwood guy. It was the fuel sending unit's electrical harness.
My mechanic didn't want to change just the harness and had me buy a new sending unit. He replaced the fuel pump on his own cost (although I am not sure why, must be trying to make me happy)

Anyway, I am back to happy motoring... in 18 inches of powdered snow :rolleyes:

That harness should have been changed the first time the pump was done. They are included in the box with the pump, and there is an instruction sheet stating exactly whey it should be changed. Also, there was no need to replace the sending unit. :(

Ive never got the harness with any of the gm pumps
also they didnt offer the harness alone without
the entire sending unit, kinda a kick in the nuts
then carter starting making them up,
its too bad they replaced the unit
as I'm 99% sure the harness alone would have cured it
yesterday I replaced the harness in a 94 fltwd brhm for
the local funeral home, 70k 1 owner cleanest one Ive ever been under
this is so common its scary

glad we could help, and your back to feeling confidence
in that big caddy!!!!
