Good Morning Everyone,
I bought this 1991 K3500, 454 V-8 meshed with the 4L80e transmission. It is a tow truck and does not have the original bed on it.
The previous owner definitely knew how to cheat and short repairs in the sloppiest way imaginable. Here are a few things I found, just for laughs and then I'll post my question.
Wiring to the transmission were just twisted together and not protected from shorting out.
Fuel pump assembly was RTV'ed into place.
A fuel pump switch was installed on the dash, when the only thing wrong was the pump relay.
Exhaust was hacked into 6 pieces and left hanging. I think they did this to work on the transmission.
They didn't use butt connectors for any electrical repairs. My collection of wire nuts is building the more I work on it. lol
The fuel fill hose was ran in such a way that the neck was kinked to almost closed and rain could easily get into the tank.
OK, maybe you get the picture.
Now, I'm going thru and "tinkering" with this truck in my spare time and the latest focus is the fuel gauge.
With the RTV mess they left on the fuel tank and pump assembly, I just replaced both. Don't have the patience to try and clean it up.
The new sender is putting out proper ohms, got rid of the fuel pump switch on the dash and got that system working correctly, But the fuel gauge is now showing full grounded condition..
Ok, now, I haven't pulled the cluster out yet but doing some research, this gauge cluster is not from a 1991 truck, but rather a 1994 truck. With the other "repairs" I'm finding, I'm almost scared to look behind the cluster. lol
So, I've looked thru the Chilton and can't find the electrical schematic for the 1994 instrument cluster but do have it for the 1991 but I know the connector is different between the 2.
Simple question... Is the wire for the fuel gauge on the '94 purple like it is on the 1991?
I'm hoping I don't have another tweeker repair behind the cluster. lol
I'll be able to look at it this Sunday and just want to go in with some information I can't find in the Chilton.
