a few general questions about my truck.

[97blueyuk]

Okay before I get elbows deep in this truck I am looking for some suggestions.

The fuel gauge does not work at all although randomly the needle will start spinning sometimes full circle (unless the oil pressure needle stops it). Should I look at sending unit or electrical?

Some gas is collecting on the frame below the tank I am thinking this is a loose clamp.

Where the front driveshaft comes out of the tcase I am getting fluid leakage, looks like a yellowish fluid. Could be a bad seal or wrong fluid maybe both or more. Any ideas?

4wd buttons not lighting up and not always engaging/disengaging 4wd. Bad switch?/ bad actuator or could it be more serious?

and the back door windows only go down about 5 inches, could this be a safety system?

before I start throwing money and parts at this I would like to get some direction

thanks all

The fuel guage issue is pretty common usually an issue in the cluster, theres a place you can send it to and have it fixed and they will look the whole cluster over, and the rear window thats how they are cause the wheel well is in the way of them going down anymore

remove tank and see if the fuel is coming from the pump unit while it is done measure resistance on the terminals that the purple and black/white wires in the harness attach to.
fluid should not even look yellow only red flush it out of there. and while you at it check the color and level of tranny as well.

for tcase check for loose, missing or blown fuses #2, 4 and 24.

thanks for the answers so far. about the pump unit resistance what range should it be in? Will def be flushing the tcase this week, I was thinking it didn't look right

empty tank should give you about near 0Ω and full tank should give about 90Ω.

had the cel scanned yesterday, came up with a bunch of codes. 1 for each bank o2 sensor, 1 for each bank catalyst (hopefully related to o2), coolant temp loop, and a miss cyl 6 and a general miss. time to do some shopping i guess.

 

[SunlitComet]

how about posting the codes and email me your email thru my profile page so i can get you testing sheets for each code before you start buying thing you may not really need just yet. if you killed each o2 sensor and a temp circuit and have cylinders dropping out i seriously doubt at this point that they are all individually broken.

Im in the same boat as 97blueyuk. I just got a 96 4wd 4 door and its my first 'hoe. I know I need front end parts but how common is a center link replacement? Any and all help is greatly appreciated because most of my chevy knowledge is all 2wd and pre-'72.

 

[SunlitComet]

center link is only needed if the holes in it are corroded or otherwise damaged.

thanks sunlitcomet, I will go get it scanned again and get the codes, and get them too you.
