On a full tank, the gas gauge would only read 3/4 full. This has been going on for several years. Now, after more troubleshooting, it appears that oxidation on the contacts behind the instrument cluster was the reason that the gas gauge would only read up to 3/4 full even when the gas tank was actually full. I also noticed that depending on how you “seat” the instrument cluster in the dashboard can also affect the amount of electrical contact between the connectors and the printed wiring on the back of the instrument cluster. This could be due to damaged areas on the printed wiring. It has to be seated “just right”.
For example, after I filmed this video, I pulled out the instrument cluster again to adjust the shifter cable that clips to the steering column. When I reinserted the instrument cluster and tested it, the gas gauge showed only ¾ full (on a full tank)! Nooooooo!!! But when I adjusted the way the instrument cluster was “seated” against the connectors and tested it again, the gas gauge immediately read “full”.
Of course, the printed wiring is very fragile, and you have to be very careful handling the back of the instrument cluster. There is probably only a finite number of times that the instrument cluster can be removed and reinserted before the printed wiring fails. If that happens, it would probably require manually repairing the printed wiring with some other conductive material painted or spliced in its place.
Please add your comments below on any similar issues you encountered and any fixes (successful or not). Thanks very much for watching!
If you've been following this channel, you'll know that in prior videos, I replaced the gas gauge with a new old stock OEM gauge, and also replaced the fuel sending unit. Neither fixed the issue. I also did some troubleshooting in an attempt to diagnose what’s causing this, and had narrowed it down to a partially bad ground somewhere up at the front of the car between the instrument panel and the fuse box.

Good luck! It was a real pain to figure out.

You can remove the speedometer cable before you pull the cluster. I'm not sure if that helps relieve any of the "pulling" or stressing on the printed circuit board. Also, you can use a pencil eraser to remove the oxidation if you don't have a Dremel. I haven't had to do this yet on my '83. Great video! If all else fails, Dakota digital and Intellitronix make direct fit replacements. They're pricey, but at least they're available. Thanks!

Hi @longologo productions! Do you know if any website selling all complete fuel injection kit to the 305 5.0L (4BBL) from 1985? Had a look on rock auto but could not find any. Would you have any idea if it is complicated to install and ind the end worth it? Thanks again, great channel and video!

@@AmyDuesenberg : The shop manual has a bunch of (confusing) info on the doors. Someday I’ll do a video on this because I also need to replace the sweeps. Anyway, here’s exactly what it says: “1. Remove trim panel and detach insulator pad (if so equipped) and inner panel water deflector. 2. Remove two glass belt line, support clips and trim support retainer (9 and 8, Figs. 5-61 and 5-65). 3. Slide glass straight down (glass suction cups may help) and remove from inboard side of door. 4. To install, first spray glass, run channel with silicone spray or liquid soap solution, then reverse removal procedure. Tighten attaching screws with hand screwdriver.” Fig. 5-65 shows that “8” (trim support retainer) is a piece located at the front of the rear door in front of the door lock mechanism and it looks like there is a single screw perpendicular to the inside surface of the door. “9” (glass support clips) are shown in the figure as two sort of U-shaped clips that support the glass from the bottom and each having a screw perpendicular to the inside surface of the rear door. What I can’t tell from the pictures and the diagrams is whether any of the interior sheet metal is blocking access to these screws or whether any of the rivets on the inside of the door would need to be drilled out. It seems like there are enough openings on the inner metal that you could partially roll the window down to access, the two glass support clips. You might also be able to access the screw for the trim support retainer through one of the holes in the interior sheet metal. Let me know whether this helps.

Hi bro What’s name of manual book that you use?

@LongologoProductions 2 ай бұрын

It’s the standard shop manual for the GM cars of that model year. You can find some on eBay or even digital versions on CD on Amazon.

That’s so frustrating. There are so many little things that could affect it-a bad ground somewhere, or even just a bad gauge.

If you can find a good one and if that’s the cause of the issue. But if you have a bad ground somewhere else then replacing the cluster won’t help.

Why doesn’t it have a temp gauge

@LongologoProductions 9 ай бұрын

@jerronthomas6565: That's because I have the base instrument cluster, and not the gauge package. The temperature 'gauge' on my instrument cluster is just a red light that you hope doesn't come on!
