Question about Isuzu Cars & Trucks

Open Question

My Isuzu gas gauge does not read well sometimes it says the tank if full while it is only a quarter, sometimes it says its empty when there is gas and it continues fluctuating and you never know what the problem is. One thing i noticed is that after travelling for sometime when I open the gas lid, there seems to be some air pressure coming out, it looks like the tank is being pressurized during driving.

SOURCE: Gas gauge reading is erratic.

Your sending unit is getting flaky - it's a known issue. You can repair it though, rather than buy a new sender.

Do not do this job with any more than a 1/4 tank of gas or you'll get a fuel bath in the trunk.

Here's a DIY procedure on how to do it - 99% of the time on these cars, when there's a gas gauge issue, it's the broken wire they show in the procedure. I was out of solder at the time I fixed mine, so I used barrel clamp connectors to crimp a jumper wire into place on the broken ends of the wire, and that fixed it permanently.

Here's the link:)

Instead of replacing the sender, fix the visibly broken wire and it'll fix the failure.

SOURCE: gas gauge flucuates to empty and full so we never know if we have enough gas. What to do?

It is a common problem. It is a faulty in tank sender. You can just replace the sending unit by removing tank.

SOURCE: 2006 GMC Envoy XL gas gauge reads empty

The sulfur content in the fuel is contaminating the contacts of the sending unit.

Some people have had good luck with some fuel system cleaners solving this problem. The cheap stuff doesn't seem to do the job.

Not that GM isn't completely exonerated from fault but the gas stations don't do a very good job of watching what the stations sell.

My gas gauge read that I had a quarter of a tank and about 2 minutes later it dropped down to empty


when it dropped to empty did it run out of gas or were you able to get to a gas station and put gas in,if so did the gauge read above empty.its possible that the float in the tank or the needle on the dash momentarily stuck for what ever reason and it may not happen again.

Fuel Gauge reads empty, but tank IS full


the float in your gas tank seems to have water in it....water is heavier than gas, that's why gas floats on top of water....try putting something like HEAT in it to dry up the water in your tank....
