    What are the possible causes of a tapping or clicking sound from the motor resulting in freezing the motor up?
    The truck will no longer crank, but there is power, and it makes the attempt when you turn the key. The tapping started about 3 days ago. While driving, the tapping became louder. When we attempted to move off the roadway, (we were on the interstate at the time) the ...

    Why won't my car crank? We completely charged the battery, it's just not turning over
    My 4runner jumped fine this morning and we tried to jump it earlier and it kinda sparked. We charged the battery all day and tried to crank it and it's not turning over. It sounds like it's cranking and the battery is charged but it's not starting

      Nothing should sparked when you jump start a car. and if the starter is working then your battery is good. Start by checking for a blown fuse. if they are all good, then find out what your engine is lacking. Does it have ignition spark or fuel pressure?

    Missed an oil change, had it flushed and changed. Now the car smokes a bit on startup. What can I do?
    54K miles I don't know how long it went without an oil change, possibly 12k to 15k miles. Smoke does smell like somthing burning...could it just be the sludge residue from the flush? Can I open up the engine and look for signs of damage? What am I looking for?

      Could be the starter ?

      First, check the battery and starter cables for their tightness or free of corrosion and physical damaged.

      See this Starting system simplified diagram. Have a help from an assistant to crank the engine, use a 12 volt light tester or a digital voltmeter, apply it to the starter control circuit.
      If there is light or 12 volts and the starter isn't cranking, then the starter is the culprit. Have the starter to bench test for free at the local auto parts stores.
      If there isn't no light or no volts, then the ignition switch is the culprit.
      Check the starter relay and position the Automatic transmission shifter in neutral.

      See the starting system simplified diagram @

    Won't start. I can get the motor running with extra gas, but it stops as soon as I let up.
    Mileage: 198,000. First thing in the morning, in the garage. Engine light is on. Temp is 19° out, but it has started up fine in colder weather. This is the first time this has ever happened.
