    I turn the ignition key and nothing happens. The lnstrument lights come on, but engine not turning
    I have to turn the key 3 or 4 times before the starter gets power and turns.

      Possible bad starter. Check for battery voltage at the small wire attached to the starter solenoid. Check while trying to start the engine. If battery voltage is there (you can use a 12 volt test light) then the starter is no good.

    My battery light keeps coming on and the battery is not getting charge.
    I have already replaced the battery, alternator, and belt, Battery and alternator are new and tested

      1. At the alternator, test for battery voltage at the Black/Gray wire and the Dark Green/Orange wire with the engine running, this is powered by fuse T in the Power Distribution Center (PDC).

      2. If voltage is present on both wires, then ground the Dark Green wire. If the alternator starts charging, the PCM or its wiring are at fault. If it does not charge, then it is a bad alternator.

      Attach a code reader and read the fault codes that have stored themselves by now. This is truly the next step (the first step)

    When I turn on the A/C it makes a clunking noise, also when I am idling the motor acts like it needs a tune up
    when a/c is off it idles fine.

      see if your compressor clutch/pulley has any slop in it...if bearings are going'll start making noises

      Oil cylinder rings are probably worn, do a cylinder compression test.

      Please detail what you mean. Ignition timing is not adjustable on this engine if that is what you mean.

    How do I remove the fuile pump
    the van wouldn't start . called AAA Guy checked it out. It cranks but wont start. he gets under the the van and punds on the gas tank the van starts. said its ythe gas pump.
    • CVO

      Have you done a compression check and how many miles are on the engine? Sounds like valve guide seals, but I would do a compression check first.

    Why does my van hesitate?
    We have had fuel pump, oxygen sensors, air filter changed and had a tune up. But it still misses. It rides fine doesn't stall but kind of misses. Also it seems to have lost power. Really have to push gas peddle to get it to pick up speed. It has 130k miles hoping to ...

      Hesitation is when your engine misfires, stumbles or lacks power when you accelerate or step on the throttle. The problem often means the air/fuel mixture is not being properly enriched or is going lean, or the ignition system is weak and is misfiring when the engine comes under load or the air/fuel mixture goes lean.
      When you step down on the accelerator and the throttle opens, the engine sucks in more air. The computer should respond by adding more fuel.
      If the engine has a speed-density type of fuel injection system (no airflow sensor), the computer uses inputs from the throttle position sensor, manifold absolute pressure sensor, air temperature sensor and engine rpm to estimate airflow and how much fuel the engine needs. NOTE: Speed-density systems are much less sensitive to vacuum leaks than EFI systems that use an airflow sensor.
      If the engine has an airflow sensor (vane airflow or mass airflow), it looks primarily at the airflow signal from the airflow sensor, but also takes into account what the throttle position sensor and MAP sensor (if equipped) are telling it. NOTE: Airflow EFI systems are very sensitive to vacuum leaks, and air leaks downstream of the airflow sensor.
      Consequently, if the inputs from any of these sensors is inaccurate or missing, the engine computer may not add enough fuel, allowing the fuel mixture to go lean causing a misfire that produces a hesitation or stumble when accelerating or opening the throttle.
      The amount of fuel added by the computer when the throttle opens may also be insufficient if the fuel injectors are dirty or fuel pressure is low. The oxygen sensors in the exhaust monitor the air/fuel mixture so the computer can adjust fuel trim as needed to maintain the proper air/fuel ratio. Fuel trim adjustments can compensate for dirty injectors and/or low fuel pressure to a certain extent, but occur too slowly to offset a throttle hesitation problem.
      Vacuum leaks will typically cause the fuel trim to run rich as the computer tries to compensate for the extra air being sucked into the engine through the leak.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this).
      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

    Why am I not getting any spark from the coil?
    • Bobby
      9/9/2010 Bobby
      could be the coil is back you need to test if the coil is getting power and signal and ground, if it is then the coil could be bad. if power is not getting to the coil then it could be something else relay possibly. if there is no signal getting to the coil the crank sensor or cam sensors could be at fault. did you check for codes with a scanner?

      Check your battery cable connections, they must be clean and tight.
