Car won't start. Turns over but won't start

crank shaft position sensor

Maybe the antitheft system. Read thru this link

If it is a 3.8 engine change the crank sensor,they go bad on the 3.8 engines.

Done cars have a kill switch if they are low on oil. Check your oil. If the oil is good, it may be the ignition switch.

If the engine fires up for a second or two with starting fluid then the fuel pump is weak.I would check the fuel pressure and if its not within the specs then replace the pump and filter.

Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they just stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.

Have you hooked a scanner to the computer and checked the oxygen sensor(s)? If they are bad they could lean out the engine. The MAF Sensor can cause starting issues. Check the filter side of the MAF Sensor for any debris. I have found feathers, leaves, rags, etc. in them.

Remember an engine needs three things to work properly...Air / Fuel / Ignition(Spark)

Try spraying starting liquid at the throttle body and then start.If it starts and runs smooth then its faulty fuel pump and clogged fuel filter issue.--------

A car that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also these problems are related to faulty spark plug. Check the spark at spark plugs when you start the car. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt. If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced. If all the possible options checked out ok then check the car starter. The starter gets power from battery to start the car. If the starter is faulty then it will not let the car to start. Also check and confirm that there is fuel in the car. If its very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the car. If the car starts momentarily, then there's a good chance the fuel pump is not working or the car is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gauge and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem. Thanks. Helpmech.

Sounds like you have a bad igniter or ignition control module both are the same.Its the part that the coils are mounted on.

The battery to starter connection has power.the battery is ok.but there are many other possibilities related to battery and its other connections,the spark plugs,the fuel pump,the fuel itself,the sensors(o2 sensor,maf sensor)the valve(IAC valve,egr valve). Most probably the spark plug,the coil pack and crank shaft sensor.This 3 are not getting power to get the car start.

There are some possibilities which you will have to check in this case:--

1) First of all check the power and voltage to the battery. With meter it will show exact 12 volt if the battery is charged. If the voltage is less get the battery charged at local auto repair shop. If the battery is internally drained and not getting charged then its time to replace the battery.

2) When you crank the car do you see spark coming at the spark plug? If no then its time to check the spark plugs and coil pack. If the spark plugs are not worn out and looks new then its time to check coil pack. The spark plug gets power to spark from coil pack.

3) The other thing to check in this case is the starter solenoid of the car. If the battery is charged and you start the car then it gives power to the starter to start the car. But if starter is faulty or not connected properly then car will not start.

4) The other thing to check in this case is fuel in the car. If there is fuel in the car then check the blockages in the fuel pump if the fuel pump looks proper then check the fuel filter above the fuel pump.

5) If all the above possibilities mentioned above checked out OK/perfect then it's a electrical issue and the wiring's in the car needs to be checked. The car gets power from the battery to get started. so the wires from battery needs to be checked one by one.
