Hi, this is being caused by a malfunctioning sending unit that is locate inside of the tank and is part of the fuel pump assembly. replacing the sending unit will fix this issue.

Please rate and god bless:)

    Hi, its not the fuel pump, its the sending unit. the sending unit is part of the assembly that the fuel pump is attached to. your fuel pump is fine.

2005 chevy cavalier gas gauge doesnt work goes into the temp gauge and when i try to put gas in it spills out like it is full.


It sounds like the fuel gauge sender unit is faulty, probably causing a wiring problem with other dash dials. Also sounds like you already full of fuel. The float and sender unit need checking and/or replacing.
(float in fuel tank). The fuel tank needs to be drained completely to do this work. Is it something you can do ? If not, it's not a major operation for a mechanic and the parts are cheap. Good luck... Red.

My Chevy cavalier 99 takes a sec to start I have to hold gas pedal to floor been like this fo at least a year I changed full regulator any suggestions it's a 2.2


if the car is fuel injected, holding the gas pedal to the floor will actually cut off your fuel injectors - which may make it worse. You need to check fuel pressure, you want to make sure the fuel pump isn't bad. Also, check your battery.

Hope this is helpful :-)

99 cavalier - the fuel gauge doesnt read accurately and it jumps


Possibly a bad ground wire at the sender on the tank,

Check for that first before tearing into the dash to replace the guage.

I am having a issue with my fuel gauge on my 99 chevy cavalier. When i get to about a 1/4 of a tank, the needle wont move any further down. Then when i turn on the car, it will jump to full, and then start...


The fuel sender unit (inside the tank) has malfunctioned i think or there is too much resistance on the wire which is caused by a rusty/corroded connection - Go to a wreckers and try a different one or just get a brand new one but it sounds like the sender unit float gets to a point then jams quite common....

99' blazer gas gauge eratic


I have the same problem on my 99 ZR2 Blazer. This is the rheostat in the gas tank. I bought my part in Ebay for $27. The only issue is that you have to drop the gas tank and pull the sending unit to install. Hope this helps, I hear from other message boards that it is a very common problem in these vehicles.
