Ok fellas one last fuel question. I chaged my o2 sensor and cleaned my tb like I was told needed to be done and my fuel stil drops drastically. But here's the deal yesterday I had a quarter tank and I put in 6 gallons so that shuld have only been about 10 gallons or so but when I turned on the car it said full tank. Now I just replaced my fuel pump twice thinking it was that but what are the odds of 2 faulty fuel pumps could it be like a fuse or something small like that that's blown or something or could it be my cluster?

 

Could be the fuel level sensor. I think it's around the fuel pump in the tank, but I'm not sure.

 

Wouldn't that have a trouble code sense its a sensor?

 

actually mine did throw a code with a fuel level sensor. i just cleared it and decided to wait on it. theres a quick chage pump you can buy, the sensor itself, or another member recomended "bending the sensor arms". dont exactly know how to do that though

 

There may be a trouble code - but some don't make your SES light illuminate.

 

Most likely is the fuel sending unit. I wouldn't trust your gauge anymore and would use mileage calculations until you can get it replaced. My tank is full all the time regardless of how much fuel is in it. It never threw a code though.
