Gas gauge barely working.

[CyberEye]

My gas gauge was working fine yesterday when I went to work, was at about 1/4 tank, I remember looking at it. When I came out from work, and started the car, the gauge was a little above 1/2. This confused me a little, so I turned the car off, and lo and behold the needle didn't drop down it stayed where it was. As I drove home the needle went down a little bit, to just below 1/2.
I changed my fuel pump today, the float moved freely, and I checked the resistence at the harness on the pump, and it went up and down as the float moved, between I think 12 and 38ohms if I remember correctly.

Put everything back together, needle still didn't move. When I filled my tank of afterwards, the needle went abck up to just above 1/2. So wtf is going on? Is the gauge messed up? or is the little sending unit on the pump messed up ( should it go down to 0 and higher hten 38?)

Any help would be appreciated.

Here's something you can try that worked for me when I had issues and verified that that everything was correct with the float. Remove your gauge cluster as if you were going to put on gauge faces. When I say remove, I mean completely unplug it, pull the clear plastic face piece off. Manually turn your needle to the full position after you've filled up the car so you can verify that it really is full. Reassemble everything and see if your gauge starts working again after driving long enough to make it move.

It may take a while to make it come down a bit from the top, but this is one way to tell if it's really working or not.

Hope that helps,

Andy

You have two senders, one on each side. It accounts for the saddle tank going over the driveshaft. Check the sender on the passenger side as well.

I take it that's what the access panel under the backseat on the driverside is for?
