    Vibrating noise from rear end while in park sounds like a cellphone on vibrate ringing
    While in park and also driving under 40 km I hear what sounds like a cellphone on vibrate ringing I'm thinking possibly fuel pump Any ideas?

    My vehicle fumbles under a load, but I only notice the problem when it's warmed up
    When I start the vehicle there is no hesitation, no idle problems, I can take it down the road cold and it seems to run fine. When the vehicle is warmed up and we try to drive it at 70 mph it is like it has no power or has loss of power.

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

    Starter will not turn over
    When ignition switch is turned to start position starter will not energize. All lights and indicators activate properly and can hear fuel pump cycle on then off. Battery good. Headlights bright.

      Check the voltage circuits at the starter. There should be two circuits, one is battery voltage, hot all the time. The other circuit goes hot with key in the crank position, also that circuit is wired through the neutral switch. Use a testlight to check for voltage. Any testing at the starter make sure tranny is in park or neutral and the parking brake is set.

      You have to be sure the battery has a full charge and that ground is good.

    Old gas, should I drain or mix?
    Car was idle for 9 months, other than starting it every few days to get fluids moving. Recently put some work in to fix rusted parts. Car starts and runs fine now. However I am concerned about the old gas in the car. I was worried the fuel system might get gunked up ...

      As long as the vehicle starts and runs OK, then the fuel should be okay as well. Any gasoline stored for more than 12 months will tend to lose volatility (igniteability), which could lead to hard starting or no start conditions after this long storage period. No fuel additive will prevent volatility loss in fuel.
      To reduce fuel volatility loss during storage, recommend to fill your tank at least 95% full with fresh fuel and fuel stabilizer, and store in cool conditions away from direct sunlight if possible.

      The oil pump is located inside the oil pan - bolted to the bottom of the engine.

    My car is losing water and it is added everyday. No one can find a leak. It dies when idling to long.
    car won't start unless jumped but light and all work

      "Losing water"
      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.

      "It dies when idling to long."

      The check engine light doesn't have to be ON to store a fault code. Do not skip this test.

      Check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine

      "car won't start unless jumped "

    Trouble starting when cold stalls and misfires. Then when shuts down can be driving at 60 mph and lose speed with no
    Acceleration and smells. Let cool down and you can drive it again.

      how did the plugs look when you took them out a miss on number three could have been a bad injector and a new plug could have helped it burn the extra fuel and the one cylinder running rich will lean out the rest of them causing some extra heat. i have a built up chevy and one bad plug wire will make it over heat in about 30 miles if i'm pulling something.
