98 Z28 Fuel Gauge
Hey gang, I just got my first sports car or modern muscle car, if you will.
And of course like any other used car is has a few problems.
Anyways, here is a pic of her.
1998 Z28 w/ Leather, T-tops, Headers, full exhaust system (unsure of muffler brand), with stock tips.


The good news is she only has 84k miles on it.
anyways, my buddy who I bought the car from yesterday, changed the fuel pump, and after it was all said and done, the fuel gauge doesnt work anymore...
Can anyone lead me in the right direction to fixing it?
Any common problems like this in these cars?
Please tell me I dont have to pull the tank..

Re: 98 Z28 Fuel Gauge
No common problems with the fuel gage, other then the normal, for Chevy, reads faster at the bottom the at the top.
The pump and fuel gage sending unit are attached. So in order to change the pump you have to pull both. The chances are he either got the float jammed then he reinstalled the assembly or just forgot to reconnect the wires. Normal access is to drop the tank. Or you could do the trap door trick, cut a hole in the floor.

It's never worth it to cut a hole in the body of your car to save some time on a project. Ever. Especially if you're inexperienced with the body type. And any body cutting will reduce your car's structural integrity, and depending on how and where you cut, could make the car more dangerous during an accident. If your friend just changed the pump, then he should still have the stuff to drop the tank. Just wait for a free weekend, and do it the right way.

Get subframe connectors and there won't be a problem with structural integrity at all. That's pretty weak sheetmetal you're cutting into anyway......
