Car overheated two days ago and hasn't started since. i have replaced the thermostat, starter, spark plugs, and battery. I am getting spark, fuel, and compression vehicle just is not turning over.

1. Out of GAS: It sounds crazy, but it happens!
   Make sure you check your fuel level each time before you fire up your mower.
2. Stale Gas Leads to Clogged Carburetor: How long ago did you fill up your gas tank? And how old was the gas you used?
   Gas only has a shelf life of about 30 days because of the ethanol it contains. If you have old gas in your tank, the ethanol may have caused corrosion and clogged your carburetor.
3. Clogged fuel filter: The purpose of the fuel filter is to filter out all of the sediment from the gasoline.
   This filter can get clogged up from normal sediment, or from stale gas containing ethanol.
   The lack of proper fuel flow to the carburetor will prevent your mower from starting.
   If this is the case, the fuel filter will need to be replaced.
4. Dead Battery: Batteries typically last a long time, but there isn't always a warning sign that it is going dead. Check your battery with a voltmeter to see if it's lacking juice.
   If you have a 12V battery, the voltage should read very close to 12V. If it's less, your battery may not have enough juice to start the mower.
5. BAD STARTER SOLENOID: If you turn the key in your ignition, and hear a clicking sound, it is probably your starter solenoid.
   If you notice this clicking, your best bet is to install a new starter solenoid.
6. DISCONNECTED DIRTY SPARK PLUG: Did you recently perform maintenance? Maybe you left your spark plug wire un-hooked! Be sure to check this out, this is a quick and simple fix.
   Your spark plug could also be dirty or damaged. Spark plugs are cheap, so try replacing your spark plug.

Is there an immobilizer light lit (anti-theft ) on the instrument cluster ? Pull a spark plug wire an crank the engine , Is there spark . If there is spark ,do a fuel pressure test . Do you know about these thing's I just talk about ? There are a lot of good trouble shooting videos on youtube . No Start Diagnostic Basics EricTheCarGuy

I would check to see if you have spark. If not I would suspect ignition module.

Pull all the spark plugs out and make sure the engine still spins freely. Put a socket on the crank pulley bolt and turn the engine a couple of revolutions. With the plugs out, it should turn quite easily. If not, something may have seized from overheating.
If the engine turns easily, but the starter won't work, check all battery connections for being clean and tight, also the starter connections. If still nothing, have the starter tested. Any chance any of your wiring got burned or scorched from the overheated engine? You might want to check the wiring harness around where all the smoke was coming from.
Good luck. If you get the engine cranking, and still won't start, begin checking for spark at the spark plugs.

Hi, when you turn the ignition to start that the engine turning not at all. If your car engine turning but do not pick up. There is only this three things can start your car.
1- Fuel
2- Spark
3- Compression.
If you have fuel look for spark, If you have spark look for fuel, if you have both do compression test.
If no spark check your leads or coil packs
if no fuel check your filter is not block it or fuel pump.
If your engine is not turning at all check your battery or your starter.
Give more information do you have pack coil for each plugs or loose plugs wires.

When it doesn't start have you tried to see what is missing , spark or fuel ? Pull a spark plug wire off of a plug an get a spark tester at the auto parts store . Hook up a fuel pressure gauge an test fuel pressure . When you find out what's missing look on youtube for video's on how to test ,fuel system or ignition system . Or Take your vehicle to a qualified repair shop.

1. does it turn over? if so, strong, or weak? 2. did you replace the fuel filter? 3. coil packs, or distributor (pack(s) can be tested) if distributed check cap and rotor, replace coil, but first check starter relay - 4. Check all ignition fuses, starter fuse - (along with relay{above}) 5. Check all connections from battery - positive, negative etc.
Please let me know if you need further assistance.

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.

If all the coils are giving spark now,then you moat likely have gas fouled plugs now,so change them out with new ones,all 8 of them.If you do not have spark on all plug wires,pull the timing belt cover,and align the cam shaft and the cam,to see if the belt has jumped.If It hasn`t,replace the crankshaft sensor.
