Hi,
It sounds like you have a fuel level sensor that is starting to go bad. This sensor is located in the fuel tank, and depending on the age of the van, will probably have to be replaced.
My fuel gauge, odometer and radiator gauge isn't working and my radio says locked. How can I fix this?
sticking float on the fuel pump, or malfunction in the float
Head gaskets!!
Top rear of the engine next to the distributor.
needs a thermostat
Most of the time it's the fuel level sender in the fuel tank if your gauge moves around a bit but doesn't read correctly. If the Gauge is stuck on full all the time, the gauge itself is broken.
needs a fuel level sending unit 100 percent sure
is the coolant disapeering at all ?
sounds like the alternator is going bad.
THE temp sending unit 4 the inside gauge usally has 1 wire & the sending unit 4 the Computer has 2 wires.
ground wire from tank to frame needs to be cleaned and remounted
with a full tank of gas the gauge will drop to "E" then after a few seconds it will jump back to correct reading.
