from what you are describing you have two(2) different problems
1- the wacky gauge- its acting like a grounding issue- wires are crushed/smashed on tank connector
2- not filling - venting issue- vent line to top of tank pinched
3 solution- run tank down to 1/4 or less and DROP tank down to inspect wires and hoses- sounds like at some point in time the tank took a hit and wedged itself upwards against the underside,pinched the vent line so there is too much pressure in tank and also crushing the wires/plug causing the erratic readings(worse with less weight as the tank moves more)
if unsure of how to do this- you can get a manual such as a HAYES book at auto parts story- good luck

hi it can really only be two things, first is the fuel sender on the pump inside the tank it could be stuffed or sticking causing a false reading, second it can also be a faulty fuel gauge on the dash.

Fuel& Temperature Gauges are sticking Example gas tank full of fuel but only reads half full, temperature reads hot but engine is running at normal temperature What is wrong and how can we fix it


they could be seperate problems. the fuel level sender in the tank may be bad. the 2 wire coolant temp sensor may be faulty. there may be a bad ground some where or a bad connection in the harness. although it is common for the circuit boards in the cluster to go bad and you get funny readings on one half or the other. i would start diagnosing the cooling problem first. those engines have an air bleed valve above the t-stat. make sure there isnt a pocket of super heatad steam in the system (first indication of a small leak). the cts also controls the fan relays through the pcm. are the fans comming on as the temp guage passes half way? what does the guage do when the key is on, engine off, cts unpluged, and the connector jumpered or grounded? the guage should have a full sweep if it doesnt sweep the cluster or harness are suspect

Gas guage not reading accurate


Your sending unit inside of the fuel tank is probably faulty. Unfortunately you have to drop the tank to change it.

Fuel Gauge Stuck on Full 98 Pontiac Montana


When gauge is pegged at full, usually means a bad ground. Check wires at fuel tank, wiggle around, maybe one came off. The bad news is it is hard to get to without removing the tank. Sometimes you can reach arm in and get to them. Also check body ground at read of van.

Fuel guage reads half way and the truck runs out of gas


The float that helps detect fuel level is most likely broken. You or a mechanic will have to remove the fuel pump from the gas tank and check and possibly replace the float. Merry Christmas.
