CHEVY FUEL GAUGE SHAKES AFTER NEW FUEL FILTER IN

1998 Chevrolet Tahoe

Engine Mechanical problem
1998 Chevy Tahoe V8 Two Wheel Drive Automatic 133333 miles

I took my Chevy Tahoe to the dealer to have the fuel pump replaced cause it was making excessive noise. When I got it back, the fuel gauge would go off the guage and then shake when the car was started. The shaking continues while driving. Then one day, I drove about 30 miles and stopped the car, when I went to restart the vehicle, about 10 minutes later, it was a very hard start. I have not had the hard start again but the gauge still shakes while the car in the one position. I have checked the gas cover and it's on tight. The dealer says I need a new gauge cluster as the gauge has gone bad. I feel it stil has to do with their replacement of the fuel pump. They say they did check the pump a second time and all is ok and that their machine is reading a bad fuel gauge but it just doesn't seem right. Can someone help?

If the gauge started acting up after a fuel pump replacement then the fuel pump is the problem. The fuel gauge is part of the fuel pump on this truck.

You say the fuel gauge is part of the pump and I agree, it has to be the fuel pump that is still acting up. BUT! I can't get the dealer to listen to me. He wants me to replace the gauge cluster at an additional $500.00+. What can I tell him that will let him know I know I'm talking about? Being a woman really sux when you're talking cars, especially when you have worked with your dad on cars like I have. I know in my gut it's the pump, probably the send but I can't convince them. Help me know the words to use, other then - it didn't do this before it went in your shop.
Thanks again.

A gauge is diagnosed by disconnecting the electrical connector and installing a gauge tool on the purple wire to the gauge and you vary the resistance on the tool to make the gauge move. If the gauge moves smoothly with the tool then the problem is the fuel sender in the tank, if it still acts crazy then its the gauge in the dash. Its very hard to tell them they did nbot diagnose it correctly unless you actually have another shop diagnose that its the sender unit. But I think your only option now is to get a second opinion.

I will look into them doing that test with me looking on for results. It looks like they are going to be looking at it again anyway. It reaks gas fumes. I have left it in the house garage and you best not light a match anywhere near the garage or it will go up in flames. The dealer will look at it Monday and if no results, it's going to another dealer on Tuesday to be rediagnosed. Or at least was my agreement with the General Manager at the original dealer.
Thanks for the help. I'm hopeful they will get it fixed.
