    I had the feeling...the only place I took it thought it would run about $400-600! Been pushing the odometer button to know how much fuel I have used....time to take a look!

    Thank you-

    Warends, did you fix the problem with the sending unit?  How did you get to it?

    I have the same problem in my 2002 Olds Intrigue.

    My fuel gauge moves all over the place now I am not able to get accurret reading.

  • bschn140 May 11, 2010

    I hate to admit it, but I ran the gas tank down all the way until it died. The problem was not there before, and after, the fuel sending unit went haywire. Could there be deposits on the fuel sending unit from this, or does running it dry ruin the fuel sending unit? I know that running it dry can ruin some fuel pumps, but mine seems to be working fine.

Before you replace the sending unit try a bottle of Chevron's Techron Concentrate Plus to 12 gallons of gas in the tank. GM now recommends the use of a fuel additive (GM Fuel System Treatment Plus - part number 88861012) at each oil change which will help dissolve sulfur deposits on fuel tank sending units which causes the fuel gauge to go wacky. But Techron does the same thing as GM's additive and is widely available at auto stores and Walmart. See their site:

Classic symptom of a failing sending unit. It's inside the tank and on most cars it's replaceable separate from the fuel pump. I usually see them in the $45-75 range. Some cars have an access panel under the rear seat or in the trunk, where others require the fuel tank to be dropped - I'm not sure offhand which your car requires, however.

    Remove the carpeting in your trunk and see if you have an access panel there - it'd be probably a round cover screwed down with four or six screws, about 6-8" in diameter. If not there, remove the rear seat cushion (it'll either snap out or have a couple of screws holding it in, right along the lower front edge where it touches the carpet). If you have no access hatch there either, then you'd have to drop the tank. It's not terribly difficult but it is aggravating and annoying. If that's what has to be done, ask around at work or with friends and see if someone you know is inclined to help you out with it - you may be surprised what a friend will do for a steak dinner:)

My 2002 Intrigue will not start and seems it is starving for fuel.

You said you checked the pump. Is the pump getting voltage after the 3 or 4 seconds from the relay ?
You get voltage for the pump in the first 3 seconds then none if the engine does not start and produce oil pressure. That is to prevent a fire in a wreck.
Can you jumper the pump relay and hear the pump run past 3 seconds ?

Gas gage on full always

The most likely cause is a malfunctioning fuel level sending unit inside the fuel tank. It requires replacement of the entire fuel pump module assembly if this is the case.

The gas gage on my 2002 deville does not register correctly. I never know how much gas I have. What are the problem areas to consider?

The problem is either a faulty fuel sending unit located inside of the fuel tank, the wiring between the fuel sending unit and the fuel gauge, or the fuel gauge itself is malfunctioning.

A good repair shop can find out for you which one is at fault by dis-connecting the wiring connector to the fuel sending unit and then use an adjustable ohms box to simulate the fuel sending unit, and the fuel gauge should read at a certain level of fuel according to the amount of ohms being put through the wire.
