Default Fuel gauge dies while driving.

Does anyone have an idea as to what would make your fuel gauge read empty even though I know I have fuel. When it does die out, the CHECK GAUGE light comes on which is understandable, but it will come back on, then back off. Is it a bad relay or fuse? Or do I need a new fuel pump.

Sounds like a dead spot in the sending unit itself. Time to cut a trap door..

^ It's a rather easy one to replace (Other than cutting the trap door or dropping the tank.)

Pull the whole bucket up/out and the sending unit is on the side.

I will deff. be dropping the tank. There will be no holes cut on my Firehawk. I love my car too much. Now a WS6 or a regular trans am is ok. Does anyone have a guess as to how much this sensor cost?

Do the trap door. Your Firehawk is 100% identical to every other Firebird made.....only difference is the extra name "Firehawk".

OK, before you drop the tank, run a couple of tanks of gas with techron fuel cleaner (concentrated system cleaner, not the more diluted one) or redline fuel system cleaner. Over time there can be deposits on the sending unit; I have heard these products can help dissolve the buildup. Worth a try vs. new sending unit and dropping the tank.

I'm with you. Even in my 250K mile Trans AM I would never cut a hole to replace the fuel pump haha.

Question: How many miles are on your Firehawk? If you are dropping the tank and it has a few miles on it, it might not be a bad idea to just replace the entire fuel pump. Get a good GM one though since it's a big job. It will come with the level sensor. I think just the level sensor will run you around $100 anyways so might as well just replace the entire pump IMO.

Thanks for the advice Grimes. Ill try it.

What I dont understand is why this idea for the trap door wasn't incorporated to the F-Body when they realized it was a pain in the rear on the first models.
