    same problem ,car turns over but wo'nt start. I cleaned battery terminals,

    added water to battery cells[battery less than 2yrs old]. I KNOW THAT ON THE ENGINE i HAVE A LOWCOOLANT SENSOR NO T working.

    I have had three jumps startys but car won't crank . the car has 191,000 miles.

    so is it possible the fuel pump relay is bad or the fuel pump/gasfilter?

    how and where can i open the gas line to see if it is pumping gas?

    I have a Hyundai Elantra 2004 Diesel with a similar problem. Randomly, the car won't start although the starter is turning fine. Usually, the car would start without using the gas pedal, but even with putting the foot down, nothing's happening except the starter turning and turning. Eventually, after 5-10 attempts, the engine would come on as normal and everything will be working again until next time. Any help appreciated.

Check if fuel pump fuse is blown, and fuel filter to be clean or replace it.

    Reduce the internal pressure of the fuel lines and hoses by completing the following operations.


    After removing the rear seat cushion, disconnect the fuel pump harness.


    Start the engine. Allow it to stop by itself, then turn the ignition switch OFF.


    Disconnect the battery negative (-) terminal.


    Connect the fuel pump harness connector.


    Remove the eye bolts while holding the fuel filter nuts securely.
    Cover the fuel filter with a shop towel to avoid residual gasoline from splashing.


    Remove the fuel filter mounting bolts, then remove the fuel filter from the fuel filter clamp.


    After replacing the fuel filter, check for fuel leaks.

    Turn the ignition switch OFF.


    Apply battery voltage to the fuel pump drive connector to check that the pump operates.
    The fuel pump is an in-tank type and its operation is hard to hear without removing the fuel tank cap.


    Pinch the hose to check that fuel pressure is felt.

Car overheated, now will start if you spray starter fluid in it but will not run.

this could be several things but my guess is that you may need a new fuel pump. it runs after spraying starting fluid but not without. means its not getting fuel. check fuse, in fuse box. if none are blown. open fuel door with fuel cap off have someone listen by the fuel door turn the key on and they should here the fuel pump start to hum. if it is making a humming noise. then it could be a plugged up fuel filter not letting enough fuel to the engine. the fuel pressure switch may have went bad. if you have a pressure gauge check to see if there is the correct fuel pressure for your car.

How do you know it's getting Fuel? Sure sounds like it is not getting fuel since the car will Giggle when Starter Fluid is added.
Can you hear the Fuel pump run for a second when you turn the key to the RUN position?

Sounds like you have a weak fuel pump or a bad fuel pump relay which is a cheap test before you change the pump. You may be able to access the fuel pump through the floor under the rear seat so look at that first before you pull the fuel tank out of your car.

We have a 98 Malibu that turns over but won't start.I was told it might be the fuel pump.If I use a diagnostic meter,will a code show for a bad fuel pump?

A bad fuel pump will not necessarily show a code. If you have a throttle body try spraying a little bit of starter fluid into it. Then try to start the car. If you have it will be under under the air cleaner cover and kind of looks like a conventional carbureator. If it starts with starter fluid and then dies you have a bad fuel pump, or clogged fuel filter. The fuel pump will be in the fuel tank. Im not sure where your fuel filter would be.

I have a 1998 ford f250. I changed the fuel filter in hoping that it would stop the chugging and stuttering. It didn't and now it won't start. There is gas in the fuel line and the battery is new. ...

It sounds like you may have bad gas. Use starter fluid and spray it directly into the intake by removing the air filter and spraying it in then turn over helps if you have someone to turn it over while you spray the starter fluid. If the car starts then you have bad gas or not enough fuel pressure even know you have fuel it may not be enough if the pump is going out. But if the gas is bad it has trouble burning. If this doesnt fix it then the problem is with spark fouled out spark plugs.

Won't start. turning, but won't fire.

If you think its fuel, spray some starter fluid inthe throttle body. If it fires up, you have a fuel problem, otherwise, check your spark plug wires, distributor cap and rotor. Also, check your fuses.

Won't start

When you put in the starter fluid does it continue to run after you stop spraying it in? It sounds like you have either a bad fuel filter or more likely a bad fuel pump.
