Why are my gauge needles all fliping back and forth.

SOURCE: Gauges gone crazy

Could need new instrument panel cluster but check for corrosion as the instrument panel connector

SOURCE: Gas gauge not working

Hi,
This sounds like the sender unit in the fuel tank is worn or possibly a corroded/ bad earth from the unit itself.
There should be an inspection plate above the fuel tank removal of this should reveal the sender unit and connections, if not can you see on top of it? make sure all connections are clean and not gunged up with corrosion. Try spraying Wd40 or similar around the area whilst wiggling the plugs/wires.
Good Luck, Please press the Blue Button to appraise my FREE! Effort.

For some reason you lost power. Start at the battery, checking connections, check connections on the engine block(grounds), connections at the starter. What is the repair history on the van? Is this problem intermittent? A faulty ignition switch could cause your problem.

you probably need to replace the cable or the speedo

Well, it can be a sending unit issue, they are pretty inexpensive, so worth while to just replace it. Do be aware that the temprature DOES normally do what you describe. The condition is called heat soak, where the temp goes pretty high, due to no water circulation, after shutdown. This is normal and some vehicles run fans after shutdown to help. Usually not an issue with properly functioning cooling system that can hold pressure.

Remember the coolant recovery tanks? Their purpose was to recover teh small amount of coolant pushed out during heat soak.
