    Battery and starter checked out good, fuses all good. car wont turn over clicks only when ignition at starting position.
    what else would cause the car not to start

      Describe the click or clicking. A single heavy click or clicking that keeps clicking for as long as you hold the key in the start position? Turn on the headlamps and stand in front of the cxar so you can clearly see the headlights on. Have someone else turn the key to start the engine and look at what happens to the headlights. Do they go dim or shut off or there is not much change at all?

      there is a single click when starting the car. head lights go dim, click and swishing sounds from starter

      So if the headlights dim out then that indicates a battery issue. Try the same test again only this time have jumper cables attached and see if it starts up.

      There are abs codes and the scanner you are using can only read engine codes (P-Codes) so buy a code reader that is abs capable. When there is an abs code of any kind the computer will disable the traction control system and the abs and will illuminate both lights. As for the speedo and tach, that sounds like a bad cluster.

    Random symptoms, don't know if related. 183k+ miles, had car for last 7k, these started one by one a couple months ago
    -Engine RPM's fluctuate when idling after starting, before shifting into drive (approx. 100 RPM-range in either direction; stabilizes once shifted into drive) -1st gear acceleration more sluggish than it used to be (takes a long time to get up to speed from a full ...

      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

      The fuel smell may be related to fuel system leaks; fuel line, fuel filter, clogged charcoal canister (evaporative system), fuel injector seals.

    99 4runner coolant leak
    coolant leak on the drivers side, front end of the motor. Top and bottom radiator hoses are dry. does not leak all the time. Removed skid plate to look for leak. Can't see anything. Assume it's the water pump but it is covered up by other motor parts.

      Probably is the water pump.
      HouseCallAuto
      3/17/2014 Jeff
      is there any way to test the water pump while it's on the truck?
    • Jimm
      3/17/2014 Jimm
      Have an inexpensive (or free - with loaner tool from local parts stores) cooling system pressure test performed to determine the coolant leak source.

      If the water pump is the culprit - use these resources for the repair steps involved; www.autoMD.com 'How-To-Guides' and the website; www.autozone.com.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the water pump from around $25.00 (with gasket) for your vehicle.

      will the pressure test tell me it's the water pump or only tell me if the radiator is leaking
    • Jimm
      3/18/2014 Jimm
      Yes, the cooling system pressure test - with the engine cold - will show the specific leak point, wherever the system is leaking.

    How to get water out of fuel tank
    Well I just know it has water in tank for it has been sitting up a long time with just a little fuel in tank

      Besides having water, the fuel itself has gotten stale. Which means dropping the fuel tank and
      draining out the contents.

      Could be the timing belt area, this engine does not have a tioming chain. Hard to say what the cause is. I cannot get to hear it.

      Yea, I found out last night looking around on the net, that it does not have a timing chain. So I was kind of guessing the timing chain as well. Thanks for your advice.

    My battery kept dying so I bought a new one and tested the starter and alternater and it is still dying.
    Had the starter and alternater checked and my battery keeps dying and will not hold a charge.

      Try disconnecting the negative battery terminal each time the vehicle is parked for the period of time that you do not drive it and if the battery remains charged then you have a drain on the battery which will have to be diagnosed.

    There is a humming noise coming from under the hood.
    The humm starts when I start up and increases if I rev the engine and while I drive it increases as the speed increases

      First step raise the hood and observe the source of the noise with the engine operating. Post a reply with results for further assistance.

    I got code p0446 , what is that mean? And what should i check??
    I check online it say to check the evap valvle vent, but i do not know what this is or where is located any help would be appraciate!!

      P0446 = Evaporative Emission Control System Vent Control Circuit Malfunction

      A code P0446 could mean one or more of the following has happened:

      Faulty vent valve
      Open, short or excessive resistance on Vent valve control circuit
      Blockage of vent valve
      Bad PCM

      Possible Solutions:
      With a P0446 OBD-II trouble code, here are some things to try:

      Replace Vent valve
      Repair open, short, or resistance problem in control circuit
      Repair open, or short, or resistance problem in power circuit
      Replace PCM

      The EVAP vent valve is the electrical valve (the VSV valve), which is located under the hood near the strut tower. Next you have the canister assembly, located under the car near the rear.
      Also there is a TSB posted to correct a P0446 trouble code by installing part # 25852-20010 (EVAP hoses at the canister)
