      It could be that with 1/4 tank of fuel & on a hill the computer sees a low
      fuel load & that may be your only issue

      I say that with experience on ford & lincoln vehicles & their system strategy
      Not familiar with GM CAN Vehicles from 2004 on

      I would try it with a full fuel tank to confirm that theory as it is a little weak

      Check fuel pressure at the motor after it has been sitting for awhile to see
      if the fuel pump or module holds pressure

    How to get heat in car
    We can't get the heat to work right. Even after the car has been running for hours the heater blows cold air even when driving. The temp Gage drops and goes back up when driving the car.

    I have a 2002 Buick Renzdevous for the past 3 weeks it has been misfiring, jerking etc like it has bad gas.
    We ran the bad gas out, replaced it with new and replaced the fuel filter. It will crank no problem and sometimes I can go 3-4 days with no problems. But other days it will start jerking, misfiring, and sometimes will go dead on me. But it will crank right back or ...

    What causes stalling in idle or not turning back on when turned off?
    sometimes when slowing or in idle, lights/power dim and car stalls. At times car wont start, but battery/power works normal. When turning the key, fan and lights come on but that is it. No sounds, either.

      Check the coolant level, as the coolant heats up, the sensor is turn off.

      If the coolant is low...
      Perform a cooling system / radiator pressure test when the engine is cold - as a first step to locate the leak.
      Obtain a loaner tool / free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly, NAPA, Advance Auto, or PepBoys. Follow their instructions and pump it to an adequate air pressure 12 -15 psi or the pressure rating listed on the radiator or reservoir cap. Observe the leaks and perform the repair.
      Note: do not over pressurize beyond the pressure allowed by the radiator cap, then test the radiator cap as well.

      There may be a sensor located in the overflow bottle of your vehicle. If there is, the "cold" fill level may be below what it should be. When your car coolant heats up, it also expands, forcing some coolant into the bottle and pushing the sensor upwards, thus turning the light off.
