Need some help with a fuel gauge issue, read carefully.

[spencnaz]

My gauge on the dash isn't reading the fuel level now. Hasn't for a few weeks now.

I know there's fuel in there, I typically run the front fuel tank unless I go on long trips.

I took the sender out from the front tank a while back to put the lock ring back in place after it had popped off. After doing that, the gauge doesn't read. I have no fuel level indication now on either tank.

The fuses in the fuse box are just fine.

I can hear the fuel selector valve working when I switch tanks but again, no fuel level indication.

Is there something I'm missing here? Is it a simple fix? Is it related to the fuel selector valve?

I'm planning a drive to Idaho this next weekend and would like to have this ironed out before then.

Maybe the wiring for the sender got disturbed enough so it got loose somewhere? Pull the harness off the sender and test it for continuity and the sender for resistance, with a bit of luck that will help you figure out where the problem is.

Could it be the IVR on the back of the instrument cluster? So if you're a Russian Cowboy, do you pa russki?

Not likely to be the IVR. Pull the plug off of the FSV, and with someone looking at the guage and the ignition on, ground the yellow/white wire. This should make the gauge read full. If it does, your problem is the switch, or the senders. If it doesn't, your problem is the gauge.

I'll give that a try tonight Mel, thanks for the information. It's probably something stump simple that's wrong.

Nyet, I was only born in St. Petersburg, but even my birth certificate don't show that - don't feel like spending an year of my life in the armed forces of a country I never lived in

Confirmed last night that the sender is blown. Ordered another one from LMC Truck but it set me back 200 bucks! GGGGRRRRRRRR
